We could not complete your purchase. OS X Mountain Lion is not compatible with this computer.
Does my macbook meet the requirements for the upgrade? I'm on snow leopard 10.6.8
Welcome to the Apple Support Communities
You have an Early 2008 MacBook, and Mountain Lion requires an Early 2009 or Late 2008 Aluminum MacBook, so stay with Snow Leopard or call Apple to purchase Lion > http://support.apple.com/kb/HE57 Check if your programs are compatible > http://www.roaringapps.com

I am unable to redownload OS X Mavericks on a Late 2013 new Macbook Pro 13". I get a message saying "We could not complete your purchase" " OS X Mavericks can not be installed on this computer"
I nee an easy way to resolve this with Apple.why is it this problematic to resolve?! obviously there's a valid installer image for our macs, why can we not have access to it to use on our laptops?
I do not understand, nor accept the explanation given before - about it being a newer model... it doesn't make sense... how does that translate to "no download available".
also, if it was a valid point - we would have had that download with the release of 10.9.1 - which we don't. -
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?

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.

When I try to purchase Mountain Lion i get 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."
I can purchase other apps, why not Mountain Lion. I get the same message on my wife's IMAC.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.
Hope it helps. -
I tried to re-download Mavericks after an apparent failed attempt and now I get the message "We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed."
Can anybody help?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
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 2
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 3
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 Fusion Drive or 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. -
I'm trying to download the new MacOS. I keep getting a dialog that says: "We could not complete your purchase" and then " The product distribution file could not be verified. It may be damaged or was not signed." any ideas?
I went to Purchases and it worked from there having had the same problem you describe.

I tried to download the latest OSX for my iMac - Mountain Lion.
This is the message that I received:
"We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed."
What does this mean?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.

Reminder: create full backup before you upgrade OS

I originally purchased Aperture 3 for my MacBook Air via the App Store. There is now an update available to version 3.2.2.
When I follow the download process to update I get the message:
We could not complete your purchase.
The product distribution file could not be verified. It may be damaged or was not signed.
There are other discussions advising deleting the App Store then downloading the Snow Leopard 10.6.6 combo update to resolve this problem but my MBA is running Lion 10.7.x (as supplied, not upgraded).
I have two questions:
1. If I try to delete the App Store (by dragging it to the Trash) I get a message telling me is cannot be modified or deleted as it is part of the OS. So how would I proceed if downloading the 10.6.6 update is necessary?
2. Is it OK to download and install an update for an earlier version of OSX as I would be doing if I followed the suggested resolution?
From browsing the support discussions this seems to be a common problem for OSX 10.7 Lion users. I would expect a resolution via Software Update but all Software Updates are up to date on my MBA.Donald...
So how would I proceed if downloading the 10.6.6 update is necessary?
That won't work since you are running v10.7
Is it OK to download and install an update for an earlier version of OSX as I would be doing if I followed the suggested resolution?
No.
Since you are running Lion you can use Lion Recovery to reinstall the App Store app. -

OS X 10.6.8 - Mountain lion will not download. Error: "We could not complete your purchase."
I am currently running OS X 10.6.8 on an iMac (model identifier iMac11,1). I have purchased Mountain Lion so that we can run Adobe CC. I have been advised that Mavericks is not compatible with our proxy server.
When attempting download from the Mac app store I receive this error:
"We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed."
The following is shown in console when attempting to download:
28/11/13 10:07:24 AM App Store[1824] *** Assertion failure in -[ISDistributionManager verifyDistributionAtURL:allowsDevSign:error:distributionController:], /SourceCache/Pisa/Pisa-60.8/Source/ISDistributionManager.m:146
Please help! I have read many discussions and there doesn't seem to be a fix for this as yet. Any ideas?
Thanks.The following article pointed me in a better direction:
http://reviews.cnet.com/8301-13727_7-20081398-263/os-x-10.7-cannot-be-installed-on-certain-drives/
I tried to go the partition route, but for some reason the operation failed.
I decided to attempt a Lion install again afterwards anyway, but once again it failed, but now my whole system was hosed and could not revert back to Snow Leopard.
I did a restore from time machine. Once that completed, I attempted to install Lion again, and ta da! it works now.
What a pain. -
