    Unfortunately yes, but Snow Leopard is still a great OS in the meantime so don't rush in too quick if you really don't need to.

    It doesn't appear to be Mountain Lion compatible. See below.
    Your Mac must be one of the following models:
    iMac (Mid 2007 or newer)
    MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    MacBook Pro (Mid/Late 2007 or newer)
    MacBook Air (Late 2008 or newer)

    I have upgraded my OS into Mountain Lion and now I cannot see any net storage disks. may someone help me? thanks

    Hi kiwirudy,
    I've had the same problem more than once since I started trying to download my 14 April purchase of OS X Mountain Lion.
    I found a property list called manifest.plist in my ~/Library/Application Support/AppStore folder which had a Boolean property called failed checked. I unchecked it and afterwards I was able to resume my download.
    Here are some steps I've found useful:
    Close the Mac App Store.
    make a copy of the  ~/Library/Application Support/AppStore folder. For some strange reason the Mac App Store likes to just delete it in some circumstances, which will mean that one has to start one's download again from the very beginning.
    Double click on the manifest.plist in one's ~/Library/Application Support/AppStore folder.
    This should open it in Property List Editor.
    Expand all the nodes (holding down the alt key and clicking on the highest collapsed node should do it.
    Find a key called failed of type Boolean and uncheck it.
    Save the manifest.plist and close it.
    Open the Mac App Store.
    The red message "an error has occured" should now be gone and one should be able to resume one's download.
    In the event that the ~/Library/Application Support/AppStore folder gets deleted:
    start the download again (it will start from the beginning), pause it and close the Mac App Store.
    copy your backup copy of the pkg file back to its sub-folder (it's a numbered folder in the ~/Library/Application Support/AppStore folder).
    Open the Mac App Store and resume your download.
    It should continue from where it left off.
    This has worked for me so far. I'm holding my breath. Don't know if I'll still be alive when it's finished.
    Regards
    Nic

    Correct. Applications designed to run on the old PPC Macs (which Apple stopped making in 2005) cannot run on Mountain Lion.
    You need to update your printer driver:

  • Updated my mac to mountain lion 10.8.3 and now my app store, mail or facetime won't open. Also, I am not longer able to play videos through firefox. I tried downloading the combo for mountain lion and it refuses to install? Can anyone help me?

    updated my mac to mountain lion 10.7.8.3 and now my app store, mail or facetime won't open. Also, I am not longer able to play videos through firefox. I tried downloading the combo for mountain lion and it refuses to install saying that I need to see developer. Whenever I try to open my appstore, mail or facetime it says that the programmes need to be installed and might not be compatible with this version of mac operating system. Can anyone help me?

    It's not a bad install of Mountain Lion. I've had the same thing happen to me, but it affected not only Mail, but a variety of other programs including iPhoto and MS Office, where I had to delete preferences, caches, and reinstall the OS as well as the program itself. I'm still having issues with Mail, so I've gone to another program.
    Everything was fine upon the initial install. I restarted my iMac about two weeks after the install, and that's when the issues began to happen. I've reinstalled Mountain Lion twice, but the same issues arise.
    As I mentioned above, you'll need to figure out which preferences are causing the issue, then reinstall the program, as a fresh reinstallation will do you no good unless you wipe the drive completely.
    Here's a thread that helped me with iPhoto:

    Log out of iCloud in the System/iCloud preference pane and disable Photo Stream in iPhoto's Photo Share preference pane.  Then log back in and re-enable, respectively.  That should jump start Photo Stream.

    Restore your bootable backup/clone  or Time Machine backup of Snow Leopard, launch Disk Utility from the install disc, repair the boot volume, and reinstall Lion.

  • I upgraded my imac to Mountain Lion and my iMac has been painfully slow ever since. Any ideas what might be wrong and how to fix it?

    I upgraded my iMac to Mountain Lion and it has been painfully slow ever since.  Any ideas on what might be happening and how to fix it?

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Otherwise, take the steps below when you notice the slowdown.
    Step 1
    Launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • Hi, I upgraded to OX X Mountain Lion, and now I can't upload any pictures from iphoto/desktop to email, etc.  After I choose my file and hit "attach file" to upload, it says: "Invalid File Specified".  I am using jpg, so I'm confused. Any suggestions?

  • I have loaded Lion on my MacBook and the new trackpad functions work only on one ordinary account or user and not on the admin account. The trackpad preferences are well set. What can I do?

    I have loaded Lion on my MacBook and the new trackpad functions work only on one ordinary account or user and not on the admin account. The trackpad preferences are well set. What can I do?

    iCloud should still help you reduce some hard drive space. Just select "optimize" in the icloud tab in Mac Photo App preferences.
    Granted, not the same as completely offloading your library to a back-up drive at your location.
    Good Luck!

  • I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... The product distribution file could not be verified. It may be damaged or was not signed.

    Hi folks,
    I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... We could not complete your purchase The product distribution file could not be verified. It may be damaged or was not signed.
    Everytime I retry or continue the download I just keep getting the same error message!!!
    What can I do to get my product?
    PM

    The only thing that worked for me was to boot in safe mode.
    Power down.  Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore. 
    No trouble at all once I did this.
    Reminder: create full backup before you upgrade OS
    Hope it helps.

    I upgraded to 16 mb of ram and after 10 minutes my computer freezes, and ideas?  I have an imac mid 2011 21 inch.

    Cause and effect points to out-of-spec memory.
    Run Apple Hardware Test. Run the extended tests.

    If it fails the memory tests, remove the memory and re-seat it. The sockets are very "tight". Run AHT again.
    If it still fails, replace your original memory. If it works, you found the problem. Buy Mac memory from Crucial or OWC / MacSales.
