After Upgrading From Mac OS X 10.6

Q. Scrolling appears to be the wrong way round. Can I change it?
A. Yes. Go to Apple menu > System Preferences >
  • (for mice) click on the Mouse icon and untick the "Move content in the direction of finger movement when scrolling or navigating" option.
  • (for trackpads) click on the Trackpad icon > Scroll & Zoom tab and use/don't use the "Scroll Direction: natural" option.
Q. I can't find my User Library? Where is it?
A. Your User Library has not gone and it is in fact in the same place, but now, in Yosemite, it is invisible. To get to it just go to the Finder > (while holding the "alt" key down) the Go menu and select "Library" from the menu. You can now very easily make it visible again with Yosemite - just go to the Go menu > Home and then select "Show View Options" from the 'View' menu > TICK "Show Library Folder".
Q. I don't like the system "Resume" feature. Can I switch it off?
A. Yes. Go to Apple menu > System Preferences > General and tick the "Close windows when quitting an application" option. Alternatively if you like the feature for some applications but not others, in those that you don't want the feature you can alt-Command-Quit (Quit and Discard Windows).
Q. I don't like the new system wide text "Auto-Correct" feature. Can I switch it off?
A. Yes. Go to Apple menu > System Preferences > Language & Text and untick the "Correct spelling automatically" option.
Q. I don't like the new Apple System Information view. Can I get the original view back?
A. Yes. System Profiler has been renamed System Information and it opens with the new simplified window. To see the old style view, in System Information go to File menu > Show System Report or alternatively hold down alt and select "System Information" from the Apple menu.
Q. I don't like the new Apple Mail view. Can I get the classic view back?
A. Yes. In Mail go to Mail menu > Preferences > Viewing tab and tick "Use classic layout".
Q. My Finder windows used to show the number of selected items, disk space left and/or the path for selected items. Can I get this back?
A. Yes, Yosemite switches these off by default. In Finder go to the View menu and select "Show Path Bar" and/or "Show Status Bar" as required.
Q. I have a NAS drive but although I can connect to it I can no longer use it as a Time Machine backup destination. What's wrong?
Q. I have a NAS drive but can no longer connect to it using the AFP protocol. What's wrong?
Q. I have a very old AppleShare IP (ASIP) server but can no longer connect to it using the AFP protocol. What's wrong?
A. AFP servers must support the Netatalk v2.2 protocol or later to work with Yosemite.
  • Apple has disabled AFP support for the Diffie-Hellman Key Exchange (DHX) Protocol ("DHCAST128"). DHCAST128 is often used by NAS boxes, mainly because it has fewer overheads. DHCAST128 is deprecated and replaced by Diffie-Hellman Key Exchange 2 (DHX2). The minimum size of the prime is increased to 512 bits to improve resistance to numerical methods of attack.
  • You should contact your NAS provider for an update to the NAS software.
  • For a list of potential NAS products affected with information, links and software updates see this article.
  • Apple has now officially stated a workaround in this technical support article.
Q. Where has Front Row gone?
A. Front Row is no longer included with Yosemite. Alternatives include:
Q. Where has iSync gone?
A. iSync is no longer included with Yosemite. It has been replaced by iCloud.
Q. I'm trying to open an application but Yosemite keeps popping up the message "You can't open the application your application name here because PowerPC applications are no longer supported". What's wrong?
A. Yosemite no longer supports PowerPC applications/the Rosetta environment. See this article.
Q. I have the Apple USB Modem but under Yosemite I cannot get it to work. What's wrong?
Q. I use to use my Mac as a fax machine. This option seems to have disappeared from System Preferences. Can I use my computer for faxes?
A. The Apple USB Modem is not supported by Yosemite as the USB modem is a 32-bit device (and Yosemite is 64-bit) so fax options have been removed from the system. You will need to obtain a Yosemite compatible third party modem and/or fax software. Possible alternatives are:
Q. I'm trying to move an application out of the Applications folder but it just creates an alias. What am I doing wrong?
A. Nothing. Yosemite has changed the permissions on the Applications folder. To move an application out of the folder you now need to "copy" it (by dragging and holding the alt key down) first. Then you can delete the original from the Applications folder.
Q. I'd really like to use the original QuickTime 7 Pro. Can I still do this?
A. Yes.
  1. Download the QuickTime 7.6.6 installer.
  2. Install QuickTime 7.6.6.
  3. Go to Macintosh HD > Applications > Utilities and open QuickTime Player 7.
  4. In QuickTime Player 7 go to QuickTime Player 7 menu > Registration… and enter your registration code.
  5. If you can't remember your registration code go to the Apple Store online e.g. Apple Store UK.
  6. Click on "Account" in the top right.
  7. Click on the "Downloadable software purchases" and login if necessary.
  8. The "Software Download History" page should load and your serial number will be listed on it.
Q. I've heard something about a low-power wake mode (sharing resources without the need to turn on the monitor or attached USB devices) called "Power Nap". I can't find this in the Preferences anywhere. How do I utilise this mode?
A. Yosemite does indeed have this feature but it's not obvious because the "preference option" is named the same in previous versions of the OS. In Yosemite you simply need to go to Apple menu > System Preferences > Energy Saver and make sure the "Wake for network access" is ticked. Unlike previous versions of the OS this option allows the computer to wake in low power mode at the following times:
  1. When a user at another computer accesses your computer's shared resources.
  2. At regular intervals so that your computer can notify other computers on the network that its resources are available.
Not all Macs support this feature as it appears to be dependent on the hardware in your computer, so basically older computers won't support this feature. Macs that officially support "Power Nap" include:
  • MacBook Air (Late 2010 or newer) - supported with OS X 10.8.2 or later
  • MacBook Pro with Retina Display (mid 2012 or newer)
  • Mac mini (server) (Late 2012 or newer)
  • iMac (Late 2012 or newer)
  • Mac Pro (Black 2013 or newer)
Q. When I copy files from one place to another that has files with the same name the new dialogue window does not have the "Don't Replace" option/button. What do I do now?
A. Yosemite works differently to previous OSes and there is a new dialogue window for such instances including a "Keep Both Files" option. Basically Yosemite copies/moves all unique files first (unlike older OSes) and then gives you the dialogue window for the files with the same name with the following options:
  • Keep Both Files: this will keep both files with the same name, it will add "copy" to the filename of the items you are moving/copying
  • Stop: this is now the equivalent of the old "Don't Replace" option
  • Replace: this is the same as before where it will replace the items with the same name with the items you are moving/copying
Q. I'm trying to browse web sites but all the texts are coming up with the letter A in a square. What's wrong?
A. You have a font problem. Try these:
  1. If you are using a third party font manager e.g. FontExplorer or Suitcase Fusion check for updated software.
  2. If you are using a third party font manager e.g. FontExplorer or Suitcase Fusion check you have not enabled fonts that will "conflict" or "override" the System fonts.
    • FontExplorer: Go to the "Tools" menu and make sure "System Font Protection" is unticked.
    • Suitcase Fusion: Go to Suitcase Fusion > Preferences > Activation tab and make sure "Allow Suitcase Fusion to override System Fonts" is unticked.
    • FontAgent Pro: Go to FontAgent Pro > Preferences > and make sure "Manage System Fonts" is unticked.
  3. Make sure your (required) fonts are stored in the correct Mac OS X locations:
    • Macintosh HD > Library > Fonts folder.
    • Macintosh HD > System > Library > Fonts folder.
    • Macintosh HD > Users > ~your home directory > Library > Fonts folder.
  4. Reboot to your normal boot disk in Safe Boot Mode to clear (font) caches.
  5. Nuke your font caches.
  6. Go to Macintosh HD > Applications > Font Book and Select All (Command+A) fonts. Then try each of the following:
    • File menu > Validate Fonts.
    • Edit menu > Resolve Duplicates.
    • File menu > Restore Standard Fonts.

After Upgrading From OS X 10.7 or earlier

Q. I keep getting banners and alerts in the top right of my screen. How do I change this behaviour/stop them appearing?
A. Go to Apple menu > System Preferences > Notifications and configure them accordingly.
Q. The system "Resume" feature has changed since 10.7. What can I do?
A. Whereas before you unticked an option in System preferences you must now go to Apple menu > System Preferences > General and TICK the "Close windows when quitting an application" option.
Q. Is Adobe Flash included with Yosemite?
A. No. If you need it download it from Adobe.
Q. I had Adobe Flash already installed but Yosemite says it is out of date and has been disabled?
A. Yes, you haven't kept your Flash plug-in up-to-date (which is a big security risk - naughty naughty!). Download the latest version from Adobe.
Q. I went to System Preferences > Sharing and "Web sharing" is missing. What happened to it?
Q. I went to System Preferences > Sharing and "Xgrid sharing" is missing. What happened to it?
Q. I want to use X11 but it's not installed. What should I do?
A. Yosemite no longer includes X11 or web/Xgrid sharing, see our Yosemite FAQ for more information/alternatives.
Q. I'm trying to run a software application but Yosemite says it can't be opened because it's from an unidentified developer. What's wrong?
Q. I'm trying to install some software but Yosemite says it can't be installed because it's from an unidentified developer. What's wrong?
A. Probably nothing but make sure the software you want to run/install is legitimate and is not malware. Yosemite includes an enhanced security featured called Gatekeeper. Check out our article all about it.
Q. I've heard Yosemite supports using more than one Time Machine backup device. How do I get this to work?
A. You can "add" additional devices in the Time Machine preferences or select the option when connecting another drive.
Q. Safari doesn't appear to have an RSS facility or the activity monitor window. Are there alternatives?
A. The Activity monitor within the Safari application (not the general application in Utilities) is gone - it's not likely to come back. If you still want RSS feeds you could use a different web browser that does support them or use a dedicated RSS software application:
Q. Safari appears to have lost the ability to change the default font and size (used to be Appearance in Preferences), block pop-up windows and empty its cache (latter two used to be on the Safari menu). Are there alternatives?
A. "Block pop-up windows" is now in Safari menu > Preferences > Security tab.
A. Minimum font size is now in Safari menu > Preferences > Advanced tab
A. "Empty cache" is now available only when you have enabled the "Develop" menu (go to Safari menu > Preferences > Advanced tab > Show Develop menu in menu bar).
Q. Where's iChat gone?
A. It's been replaced with the Messages application.
Q. I've heard Yosemite has AirPlay video mirroring to an Apple TV. How do I get this to work?
A. Your (second generation/small black) Apple TV must be up-to-date. Only certain Mac models support AirPlay video mirroring, they are:
  • iMac (Mid 2011 or later)
  • Mac mini (Mid 2011 or later)
  • MacBook Air (Mid 2011 or later)
  • MacBook Pro (Early 2011 or later)
If you have a compatible Mac go to Apple menu > System Preferences > Displays > click the "AirPlay Mirroring" option near the bottom and select "Apple TV". Alternatively, when a compatible Mac with Yosemite detects an Apple TV on the same network, the AirPlay Mirroring menu item appears in the menu bar and this can be used to turn the feature on. In addition audio can be streamed on its own - audio from your Mac is wirelessly sent to your Apple TV. You can use this feature independent of AirPlay Mirroring by selecting your Apple TV in the Sound pane of System Preferences.

After Upgrading From OS X 10.8 or earlier

Q. The Network Utility application (previously in Macintosh HD > Applications > Utilities) has gone. Is it still available?
A. Yes, but it has moved. You can access it in one of three ways:
  1. Go to the Apple menu > About This Mac > Overview tab > System Report… button (opens the System Information application) > select "Network Utility" from the Window menu.
  2. Go to Macintosh HD > Applications > Utilities > open System Information application > select "Network Utility" from the Window menu.
  3. Go to Macintosh HD > System > Library > CoreServices > Applications > open Network Utility.
Q. The RAID Utility application (previously in Macintosh HD > Applications > Utilities) has gone. Is it still available?
A. Yes, but it has moved. It is now found in Macintosh HD > System > Library > CoreServices > Applications.
Q. I can access Wireless Diagnostics from the Wireless menu (using the Option key) but where is the actual application located on the hard disk?
A. Yes. There is a Wireless Diagnostics application found in Macintosh HD > System > Library > CoreServices > Applications.
Q. I used to be able to turn off text smoothing for font sizes below a certain size in System Preferences > General but I can't find that option now. Is it still available?
A. No. It's been removed from Yosemite.
Q. Is my personal Library folder still hidden?
A. Yes. But with Yosemite you can now very easily make it visible again - Go to the Go menu > Home and then select "Show View Options" from the 'View' menu > TICK "Show Library Folder".
Q. If I held the Command key down when opening a folder in the Finder it would open in a new Window but now it opens in a new Tab. Can this be changed?
A. The Yosemite Finder has changed (with the new Finder Tabs feature) so the default preference is to open new Finder windows in a new tab. You can change this setting back by going to (Finder) Preferences > General and UNTICK "Open folders in tabs instead of new windows".
Q. I had the Finder set to "Always open folders in a new window" but this no longer works. Why?
A. The Yosemite Finder has changed (with the new Finder Tabs feature) so this preference has been removed and is no longer available, sorry.
Q. I have lots of Finder windows open. Is there an easy way to turn them into a tabbed Finder window?
A. Yes. Go to Window menu > and select "Merge All Windows".
Q. When I browse web sites using Safari I keep getting asked whether to allow a plug-in to work. What's that about?
A. Safari now has plug-in control on a per website basis. You can manage which websites can load plug-ins e.g. Adobe Flash by going to Safari Preferences > Security > Manage Website Settings. You can see all the browser plug-ins installed and a list of sites that want to use them. There are five options: Ask, Block, Allow, Always Allow, and Run in Unsafe Mode (Run in Unsafe Mode removes the plug-in from being "sandboxed" which is generally unwise as it is a security risk - only choose this option if you really need to).
Q. I've heard Safari can now save credit card details using the new iCloud Keychain feature. Is there a way to stop this?
A. The iCloud Keychain is an optional feature. However, if you have switched it on/are using it and don't want to store credit card details you can turn just those off by going to Safari Preferences > AutoFill > and UNTICK "Credit cards".
Q. The directions in the new Maps application are in kilometers. Can I switch this to miles?
A. Yes. Go to Apple menu > System Preferences > Language & Region and change "Region" as required and also click "Advanced…" > General tab and set "Measurement units" as required.
Q. The new Notification Center is really annoying. Can I switch it off?
A. Not totally but here's a handy tip: Go to Apple menu > System Preferences > Notification Center. There is a new "Turn on Do Not Disturb" option. Set this to a small timeframe while you are usually asleep e.g. from 4 a.m. to 3:45 a.m. However, note that Yosemite does use Notifications for some important system notices like software updates so use this feature wisely.
Q. I'm having problems file sharing to a Windows computer/connecting to a Windows server. Is the new SMB2 protocol in Yosemite causing issues?
A. Probably. You can control which protocol is used to connect to file servers in the Finder > Go menu > Connect to Server… dialogue box by using:
  • cifs://server.name.or.ipaddress = SMB1
  • smb://server.name.or.ipaddress = SMB2
  • afp://server.name.or.ipaddress = AFP
Q. I have multiple monitors but it all works differently in Yosemite e.g. the Dock and menu bar are available on all screens. How do I get Yosemite to work like the old versions of OS X?
A. Go to Apple menu > System Preferences > Mission Control > Displays section at the top > UNTICK "Displays have separate spaces".
Q. The Dock is supposed to be available on multiple monitors but I can't see it. What's wrong?
A. Nothing. To save space and confusion it only appears when you try and drag something to the bottom of your screen - then it appears.
Q. Some of the new power saving options sound great. What should I do to enhance my battery life?
A. Go to the Battery menu item and it now shows applications that are using significant power - go to each application that is listed and quit it when not in use.
A. App Nap can be disabled/enabled for individual applications by Get Info on the application icon and ticking the "Prevent App Nap" option (if the developer supports App Nap for their application).
Q. I really like the Dictation feature of OS X but it requires the internet. Is there any way to use this feature offline?
A. Yes! Go to Apple menu > System Preferences > Dictation & Speech > Dictation tab > TICK "User Enhanced Dictation" (Dictation needs to be switched on for this option to be available).
NOTE: After you switch this feature on OS X will download and install the local Dictation services to your computer. The files/data can be quite large (~500MB+) so make sure you have a speedy connection to the internet or you are prepared to wait for the files to download!
Q. My computer is set to sleep after a certain amount of time but if I am near the computer it won't go to sleep. Is my iSight camera/computer watching me?
A. No! Yosemite uses the ambient light sensors to sense movement in the near vicinity of the computer. If it senses movements it will delay the computer going to sleep.
NOTE: This could be a security risk if you normally let your computer sleep after a short period of time. If you are security conscious you should setup and use a sleep "corner" in System Preferences or if you have a laptop close the lid before stepping away from your computer.
Q. Most Apple computers include a built-in (iSight) camera. Can this be blocked using Parental Controls?
A. Yes. Parental Controls now includes the ability to disable the built-in camera.
Q. I used to use the Finder's QuickLook feature to preview videos but it's no longer working with some videos or there is a huge pause before it previews. What's wrong?
A. QuickLook now only works with MPEG4/mp4 video files. Some types of files will be converted on the fly to mp4 prior for playback (hence the pause) or they won't preview at all. You can still use QuickTime Player 7 or a third party video application e.g. VLC to playback non-mp4 files.
Q. I use Finder Labels to colour code my files and folders but now the colours have disappeared. What's wrong?
A. Labels have been replaced by Finder "Tags". You can still tag files and folders (with colours) but they no longer highlight in full colour - instead there is a Finder window column for tags which are identified by coloured dots. Tags can be added in save dialogue boxes/sheets or via the Finder - use the File menu > Tags, or right/control click on a file/folder, or drag the item to the required tag on the sidebar. To delete tags go to Finder Preferences > Tags pane > right/control click on the tag in the list that you want to delete > select "Delete Tag" from the contextual menu.
Q. I don't like the new Finder "Tags". Can I go back to Labels?
A. No.
Q. I use Time Machine to backup my computer but when Time Machine is backing up the menu bar clock icon no longer spins. Is there something wrong?
A. No. In an effort to help save battery life the icon is now static. However, an extra arrowhead now appears on the clock icon when a backup is in progress.
Q. I use special characters a lot like the Emoji font but invoking the Special Characters option or opening the Character Viewer is a real pain. Is there an easier way?
A. Yes. In Yosemite the "Special Characters…" option in the Edit menu now has a keyboard shortcut which is command-control-space. Triggering it opens a special window at the current text insertion point with access to special characters. You can even drag this window off to create a floating palette.
Q. I use special characters a lot but the Input menu in the top right is missing and there are no text options in System Preferences anymore. Can I still access these features?
A. Yes. They've just moved in Yosemite. Go to Apple menu > System Preferences > Keyboard > Text and Input Sources tabs. The "Show Input menu in meny bar" option is now under the Input Sources tab.
Q. My books have disappeared from iTunes. Where have they gone?
A. Yosemite has a new iBooks application (in Macintosh HD > Applications) where all your digital books are now stored and viewed. However, the Books tab in iTunes is still used to sync them to your iPhone/iPad/iPod.
Q. My books were stored in my iTunes Media folder in my home directory but they are gone now. Where are the book files stored on my hard disk?
A. They are now found in Macintosh HD > Users > your home directory > Library > Containers > com.apple.BKAgentService > Data > Documents > iBooks.
Q. That's great but the names are gibberish/not readable. How do I get a copy of the book/file with the correct name?
A. That's the way iBooks stores them. The best way of getting book files with a proper name is to go to iBooks and drag the book you want to your Desktop (this will give you a copy of the book file with its title in the file name).
Q: When I first used Yosemite, iTunes and iBooks some of my books didn't get transferred to iBooks. How can I get these books back?
A. Restart your computer, then open iBooks and go to File menu > Move Books from iTunes to transfer all your books correctly.
Q. I have a new late 2013 model MacBook Pro 15" Retina Display computer with a NVIDIA graphics cards and I am getting glitches/flickering on the screen. What's wrong?
A. This is a known bug. Apple fixed the issue with an EFI firmware update v1.2 on 7th November 2013 (or use Apple Menu > App Store and click the "Updates" icon at the top).
Q. I have a new late 2013 model MacBook Pro 13" Retina Display computer but the keyboard and/or trackpad keeps on stopping working/freezing/becoming non-responsive. What's wrong?
A. This is a known bug. Apple fixed the issue with an EFI firmware update v1.3 on 7th November 2013 (or use Apple Menu > App Store and click the "Updates" icon at the top).

After Upgrading From OS X 10.9 or earlier

Q. I've heard something about a feature called "AirDrop" but I cannot get this feature to work on my computer. What's wrong?
A. Not all Macs support this feature as it appears to be dependent on the hardware e.g. Bluetooth chip in your computer, so basically older computers won't support this feature. Macs that officially support "Airdrop" to iOS devices include:
  • MacBook Air (2012 or newer)
  • MacBook Pro (Mid 2012 or newer)
  • MacBook Pro with Retina Display (all models)
  • Mac mini (server) (2012 or newer)
  • iMac (Late 2012 or newer)
  • Mac Pro (Black 2013 or newer)
The iOS devices needs to be an iPhone, iPad, or iPod touch with a Lightning connector and iOS 7 or later.
Not all Macs support "Airdrop" between Macs as it appears to be dependent on the hardware e.g. Wi-Fi chip in your computer, so basically older computers won't support this feature. Macs that officially support "Airdrop" between Macs include:
  • MacBook (Late 2008 or newer)†
  • MacBook Air (Late 2010 or newer)
  • MacBook Pro (Late 2008 or newer)†
  • MacBook Pro with Retina Display (all models)
  • Mac mini (server) (Mid 2010 or newer)
  • iMac (Early 2009 or newer)
  • Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010 or newer)
† - The MacBook Pro (17-inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.
Q. Which Mac do I have?
A. You can check "Processor", "Memory" and macOS/OS X/Mac OS X "Version" by going to Apple menu > About This Mac > Overview tab if necessary (hint - clicking on the version number will give you the "build" number).
A. To check your Mac's "Model Name" go to Apple menu > About This Mac > Overview tab if necessary > check for the computer name in the top line e.g. "MacBook Pro" (this can only be checked with OS X 10.7 or later)
A. To check your Mac's model date version go to Apple menu > About This Mac > Overview tab if necessary > check the details after the Model Name e.g. "Early 2015" (this can only be checked with OS X 10.7 or later) - to be more specific and exact you can check what "Model Identifier" your Mac has by:
  • If you are running Mac OS X 10.6 or earlier go to Apple menu > About This Mac > click the "More Info…" button > (the System Profiler application will open) select "Hardware" in the top left > check what it says for 'Model Identifier' on the right.
  • If you are running OS X 10.7 or OS X 10.8 go to Apple menu > About This Mac > click the "More Info…" button > (the System Information application will open) select "Hardware" in the top left > check what it says for 'Model Identifier' on the right under 'Hardware Overview'.
  • If you are running OS X 10.9 or later go to Apple menu > About This Mac > click the "Overview" tab in the top left > click the "System Report…" button > (the System Information application will open) select "Hardware" in the top left > check what it says for 'Model Identifier' on the right under 'Hardware Overview'.
A. To check what graphics capability your Mac has:
  • If you are running Mac OS X 10.6 or earlier go to Apple menu > About This Mac > click the "More Info…" button > (the System Profiler application will open) select "Graphics/Displays" under 'Hardware' in the top left (click the triangle down if necessary) > click on the 'Video Card' on the right to see the technical information below.
  • If you are running OS X 10.7 or OS X 10.8 go to Apple menu > About This Mac > click the "More Info…" button > (the System Information application will open) select "Graphics/Displays" under 'Hardware' in the top left (click the triangle down if necessary) > click on the 'Video Card' on the right to see the technical information below.
  • If you are running OS X 10.9 or later go to Apple menu > About This Mac > click the "Overview" tab in the top left > click the "System Report…" button > (the System Information application will open) select "Graphics/Displays" under 'Hardware' in the top left (click the triangle down if necessary) > click on the 'Video Card' on the right to see the technical information below.
A. To check your Mac's "Model Number" it is usually printed/engraved on the outside of the computer somewhere (it usually begins with the letter A or M).
Q. I have multiple partitions on my hard disk and I installed Yosemite but now my Boot Camp Windows installation doesn't work/I cannot boot to Windows. What's wrong?
A. Windows requires that Boot Camp is within the first four partitions on your hard disk. Unfortunately a Mac running Yosemite has TWO additional invisible partitions on the hard disk (EFI and Recovery HD) so if you have more partitions than just your normal Mac OS X and Windows, Windows may not work. The standard setup (Boot Camp will work):
  1. [hidden] EFI
  2. [hidden] Recovery HD
  3. OS X 10.10 Yosemite
  4. Boot Camp and Windows
An example non-standard setup (Boot Camp may not work):
  1. [hidden] EFI
  2. [hidden] Recovery HD
  3. OS X 10.9 Mavericks (dual boot)
  4. OS X 10.11 El Capitan (dual boot)
  5. Boot Camp and Windows
NOTE: This is a limitation of Windows and it's partitioning scheme, not the Mac or Mac OS X.
Q. Is Java included with Yosemite?
Q. I'm trying to run a Java application/Java in a web browser but it's not working properly. What can I do?
A. Even if you previously manually installed Java you may need to reinstall it. If you need to, read our OS X Java article for information and links to download it and install it.
Q. I'm trying to print to my printer but it's not working properly. What can I do?
A. Printer drivers may need to be reinstalled after installing Yosemite. If you are having printing problems the first thing to do is reset the OS X printing system:
  1. Go to Apple menu > System Preferences
  2. Click the "Print & Scan" icon
  3. Hold down the Control (ctrl) key on your keyboard (bottom left)
  4. Click on the any printer in your printer list
  5. Select "Reset printing system…" from the contextual menu (in some cases this may take some time)
  6. When the printing system has reset and there are no printers listed in the printer list Restart your computer
  7. If your printer is supported by OS X (see this official Apple list) simply add your printer back in System Preferences (OS X may download and install the latest printer driver for you)
  8. If your printer is not supported by OS X go to your printer manufacturer's web site, check your model of printer is compatible with OS X 10.10 (Yosemite) and download the latest printer driver for your printer (it is best not to use any install discs that came with your printer as the software is likely to pre-date Yosemite!)
Q. I'm trying to install a third party application but the installer says it cannot install because the OS is "earlier than 10.6" or similar. What's wrong?
A. The third party company has coded their installer (incorrectly/badly) to only check for one digit after the "10.". Yosemite is 10.10 so the installer see's the OS as "10.1" and fails to install. You will need to contact the third party company for an updated installer.
Q. Yosemite has translucent windows. Can I turn this "feature" off?
Q. My menu bar has become transparent again. I used to be able to turn menu bar transparency off but that option has disappeared. What can I do?
A. You can't turn it off completely but you can reduce it's effect by going to System Preferences > Accessibility > Display (on the left) and tick "Reduce Transparency".
Q. I don't like the way Yosemite looks. Can I change it back to look like my previous OS?
A. Most of the new look and feel cannot be changed. However, if you find the new transparency feature/muted effects annoying you can reduce those effects by going to Apple menu > System Preferences > Accessibility > select Display on the left and tick "Reduce transparency" plus you can also try ticking "Increase contrast" too for a different look and feel.
Q. Yosemite has a new, primary "system font". Can I change this?
A. Yosemite uses Helvetica Neue as the system font. You can't change this. Well, not officially. There are third party "hacks" out there to accomplish the job - do so at your own risk - An internet search engine is your friend.
Q. In some applications when I click the green traffic light button (in the top left of the window) it no longer toggles the window size but makes the current window go full screen. Can I get the old way back?
A. No you can't get the old way back permanently. In Yosemite the green traffic light button now toggles between full-screen mode for applications that support full-screen mode. However, for those applications you can hold the Option (Alt) key down while clicking the green traffic light to trigger the old behaviour.
Q. I use Dashboard a lot but can't access it now. Where is the Dashboard?
A. Dashboard is switched off by by default. You can still enable it by going to System Preferences > Mission Control and selecting either "As Space" or "As Overlay" from the pop-up menu. You should note that Apple has deprecated the Dashboard and in future versions of OS X it may not exist at all, instead moving Widgets into the Notification Center.
Q. I use the "Reader/Reading List" features in Safari a lot but can't add items to it now. How does it work in Yosemite?
A. Reader and Reading List are still in Yosemite but Apple have simplified how they work. The Reader icon is now to the left of the search field and shown as a series of horizontal lines. Click the icon to go into Reader mode. Hover over the icon and you will see a plus button to the right that when clicked will add that page to the Reading List. The Bookmarks (where your Reading List is) icon has been changed to a "Sidebar" icon in the top left of the main bar at the top of the window.
Q. The simplified URL field only shows the primary web site domain name I am visiting. How do I see/get the full URL?
A. Just click into the URL field and the full URL will be shown.
Q. I don't like the new simplified URL field in Safari - is there anything I can do?
A. Yes. Go to Safari > Preferences > Advanced and tick "Show full website address" for 'Smart Search Field' to switch this feature off.
Q. I've heard you can initiate a Personal Hotspot on your iPhone/iPad directly from your Mac. How do you do that?
A. On your Mac, just go to the Wi-Fi menu in the menu bar (top right) and your iPhone/iPad's (hotspot) will appear as an option in the list of available networks. However, your iOS device must be running iOS 8.1 or later.
Q. How do I activate the new "Dark Mode"?
A. Go to Apple menu > System Preferences > General and tick "Use dark menu bar and Dock".
Q. In OS X 10.9 Mavericks Apple changed the way system software updates are installed. Is there anything new/different with OS X 10.10?
A. Yes. Go to Apple menu > System Preferences > App Store - as part of the automatic check for updates you now have the specific option for "OS X updates". In addition you should note that the Apple Menu > Software Updates option has gone. You must now go to Apple Menu > App Store and click the "Updates" icon at the top.
Q. I can't find AppleScript Editor in Applications > Utilities. What's happened to it?
A. It's been renamed to "Script Editor" and is in the same location (Utilities folder) but it now also supports JavaScript.
Q. I've heard there's new information about a Wi-Fi connection available but I can't find it - where is it??
A. Option (alt) click the Wi-Fi menu bar item and you now get an additional four items at the top of the menu (the interface name, MAC address, the ability to open "Wireless Diagnostics" or to switch on "Wi-Fi Logging") and you get dedicated information about the current wireless network you are connected to.
Q. Spotlight is now supposed to search the internet but it's not working. What could be wrong?
A. Go to Apple menu > System Preferences > Spotlight > Search Results > and make sure "Bing Web Searches" is TICKED.
NOTE: the order of the search categories can be dragged into your preferred order and you can disable/enable specific search options here. Unticking "Bing Web Searches" will actually prevent Spotlight searching the web which some of you may consider a good thing.
Q. Now that Spotlight can search the internet I'm concerned about privacy. What are my options?
A. Go to Apple menu > System Preferences > Spotlight and click on the "About Spotlight Suggestions & Privacy" button. This will give you details about what Apple does and exactly how to disable any "phone home" functions.
Q. I've installed iOS 8.1 on my iPhone/iPad but I cannot get iMessage, SMS and MMS messages all combined on my Mac. What's wrong?
A. First try signing out of and then back into iMessage on your iPhone/iPad - go to Settings > Messages and switch "iMessage" OFF. Then switch it back ON. If that doesn't work try enabling your Apple ID email address in iMessage - go to Settings > Messages > Send & Receive and make sure your Apple ID email address is TICKED. You should then receive a code on your iPhone/iPad when using Messages on your Mac.

Q. I'm trying to use the new sharing options e.g. Email This Page, Facebook, etc / email Markup feature but neither are working/showing any options. What's wrong?
A. As part of the OS X 10.10 upgrade the system can lose important links to these features. Apple has a quick Terminal command solution to this problem here.
Q. I don't like the new iTunes 12.x - can I go back to an older version?
A. Yes, it is possible but it is not recommended - things can go badly wrong if you don't do it right. Always make a full backup before doing trying to replace iTunes 12.
NOTE: We have now moved the rest of our iTunes 12 frequently asked questions to our new iTunes 12 FAQ article.
Q. After upgrading iPhoto won't open and it says I need an update from the App Store for compatibility with Yosemite but when I go to the App Store it says the app is not available. What can I do?

A. See our Photos FAQ.
