I can not download mountain lion on my mac pro

I am trying to download lion from snow lepard  . i only see lion icon and no download what do i do?

I'm not sure I understand what you have tried or what you are seeing. Mountain Lion can only be downloaded from the App Store (found in the Applications folder in Mac OS X 10.6.6 or later). Lion is no longer available in the App Store, unless you had already purchased it at some point before Mountain Lion was released, in which case you can re-download it from your purchase history.
First, check and see if your hardware meets the requirements for Mountain Lion:
http://www.apple.com/osx/specs/
If it does, you should be able to open the App Store, find Mountain Lion and install it from there. It will begin a 4+ GB download. When that download is complete, the installer should run automatically. If the download is interrupted, that will not happen. You can always re-start the download from the Purchases tab in the App Store.

    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s MobileMe service; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.

    And It is too slow to run Mountain Lion. I doubt it. This would not be the case if Apple Supported the Cores parallelism as they are suposed to do. I know this computer is faster than my MacBookPro; How about it Apple, Why not write software to support all my 8 cores and you won;t have to force me to stop using the new Apple System Software. Why can't we users be the ones to determine if our machines run too slow under Mountain Lion? I can't afford a new Mac Pro; you surely now how to hurt a User/Developer.

    I can't download mountain lion, I get the following message "could not complete your purchase, can't verify the file, it may be damaged or unsigned" ? what do i have to do ?

    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 just downloaded Mountain Lion for my MacBook Pro from the App Store.  Can I also download it for my iMac without paying the $19.99 fee again?

    I just downloaded Mountain Lion for my MacBook Pro from the App Store.  I was curious if it is possible to downloand Mountain Lion to my iMac without paying the $19.99 fee again?  Not trying to be a cheapskate, just curious if App Store purchases are universal like iTunes Apps.

    You can re download Mountain Lion for free on all your authorized Macs using the same Apple ID used for the original purchase.
    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.

    Install Snow Leopard on another boot partition, or upgrade Microsoft Office to a newer version, or use any number of better alternatives. Some of them are free.
    Consider
    LibreOffice (donation-supported)
    NeoOffice ($10)
    OpenOffice (completely free)
    In addition to the above I also recommend Apple's Pages ($19.99). I use OpenOffice and Pages and have been completely Microsoft - free for over a year now. Life is better without Microsoft.

    Try opening the Terminal utility in your system and running the following command to open the system's caches folder:

    Then locate and remove the folder called "com.apple.appstore" and then try relaunching the App Store and downloading the installer again.

  • Can I download Mountain Lion now but install later

    I made a " Qualifying purchases between June 11, 2012, and July 25, 2012 " so I have until August 24, 2012 to download Mountain Lion for free according to <http://www.apple.com/osx/uptodate/>

    I'd like to go from Lion to Mountain Lion when ML has nay initial bugs resolved.
    Thanks.

    Yes, the installer downloads to the Applications folder, if after downloading it asks to continue to do the installation just close that dialogue.  Later, when you are ready to install click on the installer in the Applications folder and it will do its thing.
