I have downloaded OS X Mountain Lion from the App Store. It took two hours to download but now its not running and I have no idea how to make it run!
Download was complete and I accepted everything and restarted computer but its still running 10.7.5
Any idea how to get OS X Mountain Lion to run?

What you donwloaded was the OS installer. You still have to do the installation.
To get started, double click on the download, then double click again and follow instructions.

    Is this what you see?
    That Download button is telling you it is available for downloading. Since you have paid for it and you are entitled to multiple downloads, that button is correct.

  • Redownloading OS X Mountain Lion from the App Store

    Hi,
    i need to re-download OS X Mountain Lion from the App Store, but cannot find the download. Trying to use my redeem code from the OS X Developer Programms tells me that the software is not available.
    How can i redownload the DMG to install Mountain Lion again ?
    Cheers,
    Oliver

    The redemption code can only be used once. If you downloaded Mountain Lion already, then in App Store sign in with the proper Apple ID. Click on the Purchases icon. Search the list for your download. If you don't see it then it may be hidden: Mac App Store- Hiding and unhiding purchases.
    If you are trying to download beta software, then:
    Please don't post here about beta software. There are confidential forums set aside for developers to use. Developer Forums.

  • I'm now running OSX v. 10.6.8.  I purchased OSX Mountain Lion from the app store

    I'm now running OSX v. 10.6.8.  I purchased OSX Mountain Lion from the app store & after about 40 minutes of "downloading" (started 40 or so minutes ago) my iMac restarted & I signed in.  But OSX 10.6.8 is still there & the image of OSX Mountain Lion is in my dock with the caption "OSX Mountain Lion -- Paused" !!!  ...Now ANOTHER 20 minutes have passed & no change nor other prompts nor info have come up!!  WHAT'S GOING ON???  PLEASE HELP!!! ~~~THANK YOU!!!

    THANKS SO VERY MUCH, mende1, for so quickly responding to my plea for HELP!!
    I had never turned my iMac off so I still don't understand why the download paused, & when I looked in my Applications folder there was no Mountain Lion, but your words, "However, you can pause and resume the download as many times as you want"  encouraged me to look deeper & try harder!!  I clicked & double-clicked (& multi-clicked!) the Mtn Lion icon in my dock to no avail but finally, I clicked & HELD the click for about 7 seconds . . . . . . . & then a little pop-up came & asked me if I want to "Resume the download" or stop it!! So I slid the cursor over to "Resume..." & it's downloading again!! ~~I HOPE!!  I guess 4.4 GB of OS update will take more than a little time to get in there!
    ~~~Again, THANK YOU so MUCH & God less you with a WONDERFUL time with your studies & future dreams!!!

HELP and i cannot return to my desktop with the old sofware so i cant use my computer normaly

    This error means that your hard drive is badly corrupt and cannot be repaired by Disk Utility. Since you say you don't have backups, this is very bad news. You may already have lost data irrevocably.
    First order of business needs to be backing up whatever you can, but this may be difficult to do if the machine won't start up any more. See step 1 of the following post:
    https://discussions.apple.com/message/21614450#21614450
    Once you have backed up your data, you can address the other issues.

  • Unable to download Mountain Lion from the App store

    Hi, when I try to download Mountain Lion from the app store I get the message, " The product distribution file could not be verified ... " Obviously I'm doing something really stupid. Advice welcome!
    Thanks

    A belated thanks for your help. I'd never have solved it otherwise. Maybe Apple could change the automatic reply that I got initially ("The product distribution file could not be verified ....") othewise they risk loosing customers.
    Thanks again.

    how do i delete from the startup disk? I am trying to get Mountain Lion from the App store and it says that the purchase was not complete because i need 4.06 GB space to download OS x 10.8. and to remove items from my startup disk to increase space. How?
    Thanks

    You can use iCloud with 10.7.5. You do not need to upgrade to Yosemite. You should provide a minimum of 15 GBs of free space or 10% of the hard drive's capacity, whichever is greater.
    Freeing Up Space on The Hard Drive
      1. See Lion/Mountain Lion/Mavericks' Storage Display.
      2. You can remove data from your Home folder except for the /Home/Library/ folder.
      3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
      4. Also see Freeing space on your Mac OS X startup disk.
      5. See Where did my Disk Space go?.
      6. See The Storage Display.
    You must Empty the Trash in order to recover the space they occupied on the hard drive.
    You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
    Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

  • I keep getting "hash mismatch" when trying to download Mountain Lion from the App store

    I've been trying to download the new Mountain Lion from the App Store & keep getting "hash mismatch" message. I was able to download on my 1 computer, but no luck on the 2nd computer, which is up-to-date on all updates & software. Support even put a fresh copy of the App in my account & I still get that same message. Someone suggested AppCleaner, but how do you delete the OS to re-install the new. Didn't think that was possible. Any suggestions - I've tried quitting & logging out of the App Store & even re-starting (several times)

    -  Temporarily disable anti virus software if installed.
    -  Apps such as Little Snitch, Net Nanny, and Hands Off can prevent apps from downloading including Mountain Lion.
    How to re download apps from the Mac App Store:
    Open the App Store. From the menu bar click Store > Sign In
    Click Purchases from the top of the App Store window.
    Select Mountain Lion. Then right or control click where you see Installed then click Install.
    Make sure and use the same Apple ID used for the original purchase.
