    After downloading OS X Mountain Lion, my mac has become very slow and takes a bit to shut down programmes. What can i do to bring it back up to the speed it was when i had OS X Lion

    Though I wish it were true, it is unrealistic to put 200+ new features into OS X and expect Mountain Lion to run faster and more efficient than Lion on the same hardware. I moved up from Lion to Mountain Lion. Mine is slowing down, but not very slow, as you mentioned. Safari and Mail are simply swine on launch. Check the following:
    Patience. If you are impatient and detail alters your mood, take your MBP to the Apple Genius bar.
    CPU. If you have a supported, but older MBP, your CPU may be showing its age.
    Memory. 4GB or 8GB in your MBP? Mountain Lion drinks more than Lion and if you run multiple large memory footprint applications, 4GB will be a performance bottleneck. My HD3000 graphics takes 512MB. Check the System Information report for your memory. Is it OK?
    Compatibility. Sometimes, hardware peripherals and applications are not entirely compatible with a new OS release, and divert OS performance to system log entries. A symptom is a large (> 2GB) system log file at /var/log/system.log. I just discovered a bad USB hub this way. Unplug everything and evaluate your performance again. Zero [ # > /var/log/system.log] the log file if you have the permissions.
    Permissions. Launch Disk Utility and verify/repair Disk Permissions on your Mountain Lion disk. While there, might as well Verify Disk too.
    Preferences. Sometimes, older preferences do not play well with upgraded application compatibility for a new OS release. It might be worthwhile to delete the specific preference and its lock file from Lion.
    Caches. As routine, just before I shutdown the system, I will move the contents of /Users/name/Library/Caches to the Trash. I tolerate Adobe Flash and use their preferences panel to delete all Flash content. Then on reboot, I delete the Trash. Application performance improves as a result.
    File Directory. Everytime that I upgrade OS X and run the retail Disk Warrior 4.4, it reports 25% storage fragmentation. Repairing and rebuilding the File Directory always restores noticeable I/O performance.
    Storage. If within your budget, upgrade to an SSD. Otherworld Computing has MBP SSD solutions.
    Applications. Some non-Apple applications may need recompilation for Mountain Lion, or behavior may be questionable. I compile my own MacVim editor from github sources. The same 64-bit binary that was compiled with XCode 4.3 on Lion, misbehaved on Mountain Lion. Rebuilt it with XCode 4.4 and worked fine.

  • Why am I getting a white screen after downloading to OSX Mountain lion from OSX Snow Leopard. What caused this?

    I just upgraded to OSX Mountain Lion from OSX Snow Leopard, thinking this was the thing to do.  I have NEVER had any problems with Snow Leopard, but
    after just a few days after downloading OSX Mountain Lion when I turned the computer on, the screen was white.  Stayed white.  I had to go onto another
    computer to find out what to do.  What caused this and will this happen again?

    Did you see a circle made of light grey hash marks in the center/bottom of the screen?  My iMac is 5 years old and for every update until 10.8.2 I would get the same white screen and the first few times I paniced and thought the machine was broken!  Just let it play out until the desktop comes back up and it should not do it again until you do a system update. 

  • HT201343 AirPlay Mirroring Not supported - After downloading OS X Mountain Lion I found out that AirPlay is only Supported for Mid 2011 or newer iMacs - Is there a workaround

    I got a new Apple TV for Christmas, I read tha the OS X Mountain Lion supported AirPlay with the Apple TV, so I paid for the OS upgrade.  After the upgrade I found out that AirPlay is not supported on iMac's older than mid 2011.   This ***** because this was the only reasion I needed the upgrade,   It should have been more clearly posted that the features of the new OS were only supported on specific machines!
    Short of buying a new iMac is there a way to use Airport Mirroring from my iMac to the TV ?
    What other Mountain Lion features don't work on a late 2009 iMac ?

    First, if you would have visted http://www.apple.com/osx/specs/ you would have seen there is a VERY LARGE and IN BOLD section that covers what functions of 10.8 are limited to what macs.  Second "needed the upgrade"... spare me.
    To your, "work around" question a lot of people report a third party app named "air parrot" as pretty reliable.  You're welcome to try your luck with that.

    what e-mail client do you have set to use?
    The general answer if you are using the iPhoto client is in the iPhoto preferences ==> accounts delete your e-mail account and reenter it
    OR
    IMHO the better solution is to set Apple mail as the email client in the iPhoto preferences

  • After downloading and installing Mountain Lion my iMac 27" is nearly non-functioning.  SLOW beyond endurance on my part!  This same thing happened after downloading Lion last year.  An Apple advisor had me reload it.  Still terrible!  Help?

    Has anyone had this problem?  Any solution(s) welcome!

    Thanks for the info.  I'll have to check this later this evening, since I'm in my office presently.
    However, I do think it is (was) indexing.

  • After recent update to Mountain Lion, trash won't empty completely; says "item" inuse

    After recent update to Mountain Lion, trash will not empty completely.  Always an item left in trash, and I get message that the "item is in use." Right now, using app Trash it! to get rid of that left behind item.

    Try rebuilding Trash and see if that sorts it...
    Launch Terminal and copy & paste these commands:
    Go to /Applications /Utilities/Terminal and launch it.
    At the prompt, copy and paste this command
    sudo rm -rf ~/.Trash
    Press Return.
    You will be asked to enter your admin password. It will be invisible.
    Enter it and press Return.
    Log out and back in or restart.
    Let us know.

  • Hi, an hour ago I was about 75% complete downloading OS X Mountain Lion. I was using a wifi connection on an cafe. I turned off my wifi, forgetting to pause the downloading. Now I am re-downloading from start. Is there a way to retrieve that 75% progress?

    I wouldn't do that either. Just let it complete.
    Pausing then disconnection you I net connection may drop the download again and then you may have to start over.

  • I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have

    I had iLife pre-installed on my aluminium Macbook 2009 with OSX Leopard on it. My hard drive broke but got most of the info off it and just installed snow Leopard on to a new drive and then downloaded and installed Mountain Lion over it. Now I don't have iLife anymore. How do I get it back?

    Welcome to Apple Support Communities
    Mac OS X doesn't come with iLife applications, so you have to install them manually after installing Mac OS X.
    Insert the Applications disc or Mac OS X Install Disc 2 DVD and install iLfe applications. Then, open  > Software Update, and install the latest update. If you want, you can purchase iMovie, GarageBand and iPhoto in the App Store, so you will get the most recent version
