I have a 2013 iMac, with OS X version 10.8.5.  Have been trying to download OS X version 10.9 (OS X Mavericks) without success; error message "we could not complete your purchase, the product distribution file could not be verified, etc".  Please help; TQ

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

    when ever i'm tring to install an app from the app store i'm getting the following error.
    "We could not complete your purchase - The product distribution file could not be verified. It may be damaged or was not signed".
    someone plz help me to overcome this.

    Installing the appropriate combo update may help...
    If you are running v10..7 Lion, install the OS X Lion Update 10.7.4 (Client Combo)
    For 10.6 Snow Leopard >  Mac OS X 10.6.8 Update Combo
    Then restart your Mac. Try the App Store.
    If that doesn't help, try the following..
    Quit the App Store if it's open.
    Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
    Type this exactly as you see it here:
    /Library/Preferences/SystemConfiguration
    Click Go
    Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
    Relaunch the App Store and try downloading Mountain Lion.
    You may also need to disable anti virus software and turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall

  • When I click on free upgrade to Mavericks it says 'we could not complete your purchase, The product distribution file could not be verified. It may be damaged or was not signed.' What should I do? Thanks

    Several causes for this problem have been reported. Please take each of the following steps that you haven't already tried. Stop when it's resolved.
    Step 1
    If possible, test on another network, such as a public hotspot (if the computer is portable) or the hotspot created by a mobile device. A network gateway that blocks some traffic, most likely on a company or university network, could be causing the error.
    Step 2
    Back up all data.
    From the menu bar, select
               ▹ System Preferences... ▹ Network
    If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If any proxy options are selected, make a note of them and then deselect them. You don’t need to change the bypass or FTP settings. Click OK and then Apply. Test. The result may be that you can't connect to any web server. Restore the previous settings if that happens.
    Step 3
    Rebuild the Spotlight index. If you try to search now from the magnifying-glass icon in the top right corner of the display, there will be an indication that indexing is in progress.
    Step 4
    Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

    Update: i spoke to a very knowledgeable applecare representitive who walked me thrue the process, we were trying to figure out what exactly was preventing Mountain Lion from installing & (after a process of elimination) it turns out you need to be log in as an Admin to download it, we also made sure everything was up-to-date. Downloading Mountain Lion took about 40 minutes (with roadrunner high speed internet, DSL might be a bit slower) once it was downloaded the installation process was very intuititive with just a few clicks and about 35 minutes i had the latest Operating System.

    Hello to everyone that helped me.
    I have tryed all the solutions that you have offered, but with no sucsess.
    I have also tryed to contact the support from the AppStore, but I only got the answer please contact our other collegues, from the Technical Support unit.
    I tryed as the last atemped to reinstall Lion 10.7 through the AppStore (by going to purchases) after I went through the process, downloading and installing, I could also purchase, download and install Mountainlion.
    (one small hick-up, after I finished downloading Lion, the AppStore gave me the same Message as before:
    The product distribution file could not be verified. It may be damaged or was not signed.
    I just pressed the button to download, again. After that I had no more issues.)
    I hope that this will help you.
    Best Regards
    Rene
    Hello,
    In my case, that would not be possible since before the message I have got , the system said
    "We could not complete your App Store request" or something similar.  And the only choice I had, is to click on OK button. As I said, the only way I found is to start from Mac OS 10.6 to succeed in buying, not only downloading, but simply buying Mountain Lion.
    Best Regards from France

  • Why can't I purchase and download Mountain Lion? I get the following 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?

    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 have this problem also. I was able to download Mountain Lion to my daughter's Mac Mini without any trouble. However, I can't download this to my MacBook Pro. I have read other sites that suggest VirusBarrier is the problem and recommend turning it off in VirusBarrier>Preferences>Advanced. I have tried this and it still doesn't work, although some report that it has worked for them.

    I have done Google and done the Var folder thing and deleted the folder with Apple store etc but to no avail

    Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS.  So to get help you need to give as much information as you can. Basic things like :
    - What version of iPhoto.
    - What version of the Operating System.
    - Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
    - History: Is this going on long? Has anything been installed or deleted?
    - Are there error messages?
    - What steps have you tried already to solve the issue.
    - Anything unusual about your set up? Or how you use iPhoto?
    Anything else you can think of that might help someone understand the problem you have.
