I am trying to purchase mountain lion but I get the following message:
"We could not complete your purchase. The product distribution file could not be verified. It may bedamaged or was not signed." Any help?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 -
I am running Lion 10.7.4. Tried to download the OS X Mountain Lion upgrade in my App Store - getting: The product distribution file could not be verified. It may be damaged or was not signed.
Any ideas?Launch the Console 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 Console in the page that opens.
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.
Click the Clear Display icon in the toolbar. Try the action again. Post any messages that appear in the Console window – the text, please, not a screenshot.

Hi community,
When trying to buy Mountain Lion I get: "The product distribution file could not be verified. It may be damaged or was not signed.”, any clue on how to fix this issue? It only happens in one of my computers.
In the console I get an error when trying to purchase it:
7/26/12 9:50:34.387 PM App Store: FRPurchaseManager: Preflight operation for 537386512 failed with error: Error Domain=com.apple.appstore Code=0 "The product distribution file could not be verified.

1) I deleted the /var/folders/8l folder (gets recreated when opening the app), no result.
2) Tried to check "Best attempt" for both OCSP and CRL certificate management in Key Chain.
No result in any way.
Any idea?Hello
It can be an issue related to antivirus so disable it or download in safe mode
regards -
I paid for the Mountain Lion, was downloading perfect. When almost 1 gb of downloading was left then this error occured "The product distribution file could not be verified. It may be damaged or was not signed." and stopped downloading and now every time i try to download it this error occurs
What should i do now, i paid for it and couldn't even download it now.You'll need to re-try the download.
If you have a flaky network connection, or if you're behind a proxy server, there can be issues.
The App Store knows you paid so you won't have a problem trying to re-download, but you will have to re-download. -
I just tried to buy Mountain Lion but I am getting this message, yes, even after I reboot: The product distribution file could not be verified. It may be damaged or was not signed.
I don't understand what this means? Is my MacBookPro too old to work with Mountain Lion?The Apple Support Communities are an international user to user technical support forum. As a man from Mexico my first language is Spanish. I do not speak English, however I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.

I cannot download OS X Mountain Lion, I get an error message that says: "We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed." Why am I receiving this message?

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?
PMThe 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 try to download the OS X Mountain Lion, and I keep getting an error saying, "The product distribution file could not be verified. It may be damaged or was not signed." Please Help!
If you have Intego VirusBarrier X6 installed
1. Open /Applications/VirusBarrier X6.
2. Click on the "Surf" button.
3. Click on the "Ad Banner Filter" tab.
4. Click "OFF" next to "Banner advertisement filter".
5. Start the computer in Safe Boot, then restart the computer into normal mode.
If don't not have Intego Virus Barrier installed
1. Verify that the date and time is correct on the computer.
2. Safe Boot once, then restart normally, then try downloading again.
3. Try with a different user account if the issue persists
If the issue persists
Install Lion onto an empty partition (internal or external).
Note: You can Use Disk Utility to live partition the internal drive and create a second partition large enough to install Lion.
Start from the clean installation of Lion.
Download Mountain Lion from the Mac App Store. Note that the original startup disk can be set as the destination for Mountain Lion during the installation process. -

Mountain Lion will not download to my iMac, "The product distribution file could not be verified. It may be damaged or was not signed."
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.

If you are trying to reinstall Lion, you need to use Lion Recovery
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.

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 MLion.
***** Your post is rather confusing. There's a difference between reinstalling Lion and downloading Mountain Lion. -
