When clicking 'buy' for Mountain Lion in the App store I get the message "product distribution file could not be verified, it may be damaged or was not signed' Anybody know why I get this message. Thanks
Make sure your Mac qualifies for Mountain Lion > Upgrade your Mac to OS X Mountain Lion.
If you have anti virus software installed, disable that before downloading apps.
Turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall
Try deleting the cache, cookies, and preference files (plist) associated with the App Store.
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go
Move the Cache.db file to the Trash.
Now here:
~/Library/Preferences
Click Go
Move these files from the Preferences folder to the Trash.
com.apple.appstore.plist
com.apple.storeagent.pllist
Now here:
~/Library/Cookies
Click Go
Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Empty the Trash, try the App Store. -
File and product distribution could not be verified. it may be damaged or was not signed. ?
I get this as a pop up when I try to purchase and install "Pages" and "Numbers" on my brothers iMac. Thoughts as to what I might be doing wrong?
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, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, 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, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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 (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
I have upgraded to Lion, and want to upgrade my iPhoto 8.1.2, but when I try it says it was not purchased at a MAC Apple store, which it was. Then it asks if I want to buy 9.2.3, and I say yes. It responds with Product Distribution file can't be verified. Maybe damaged or not signed. How do I get this fixed, so I can download the new iphoto's that are available.
How did you move your iPhoto library to the new system? the recommended way is Connect the two Macs together (network, firewire target mode, etc) or use an external hard drive formed Mac OS extended (journaled) and drag the iPhoto library intact as a single entity from the old Mac to the pictures folder of the new Mac - launch iPhoto on the new mac and it will open the library and convert it as needed and you will be ready move forward.

If you were using Apple's BootCamp and received this message, quit it and open Disk Uility in your Applicaitons/Utilities folder.
Select the Macintosh HD partition on the left and select Erase and Erase Free Space > Zero option and let it complete (important) this will check the spare space for bad sectors that can cause issues formatting partitions.
Once it's completed, try creating a partiton again in BootCamp.
If that doesn't work, then hold command option r keys down while connected to a fast internet connection, Internet Recovery should load (spinning globe) and then in that Disk Utility, select your entire internal drive and click > First Aid > Repair Disk and Permissions.
reboot and attempt Bootcamp again.
If you still get a error, it might be that you have OS X data on the bottom area where BootCamp partition needs to go. This would occur if you had the drive or computer for a long time or wrote a large amount of files to the drive and nearly filling it up and then reduced some, but it left traces in the area BootCamp needs to go.
To fix this
BootCamp: "This disc can not be partitioned/impossible to move files."
How to safely defrag a Mac's hard drive -
Trying to upgrad to Mountail Lion and got an error message : 403 Forbidden. What does this mean? What can I do? I had no problem when I upgraded to Lion.
403 Forbidden HTTP status code in response to a request from a client for a web page or resource to indicate that the server refuses to allow the requested action. In other words, the server can be reached, but the server declined to allow the requested access.
http://en.wikipedia.org/wiki/HTTP_403
Could you be using a different Apple ID oe such? -
^^
<Email Edited by Host>Somehow, the download is getting corrupted. First, try repairing your hard drive. Then make sure that you have disabled or uninstalled any anti-virus or internet filtering software. Also, verify that your computer's clock is set properly.
After doing all this, try downloading again. It may be worthwhile to download on a completely different network, especially since that will be the next step if re-downloading on your current network doesn't work.
PS - note that folks won't send you an e-mail directly from these forums, and posting your e-mail address on a public forum is generally not a good idea. -
Mountain Lion cannot download, need help. Says "The product distribution file could not be identified it may be damaged or was not signed". What do I do?????
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. -
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.
No trouble at all once I did this.
Reminder: create full backup before you upgrade OS
Hope it helps. -
I have tried to re-install Lion, delete different cach folders, etc., nothing is working - I keep getting the same message:
We could not complete your purchase
The product distribution file could not be verified. It may be damaged or was not signed.
Please can anyone be of kind assistance.
Thank you!
Zanjan FromerI have tried to re-install Lion
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.
For that issue, 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 MLion.
***** Your post is rather confusing. There's a difference between reinstalling Lion and downloading Mountain Lion. -
Yesterday, I purchased Mountain Lion OSX and tried to download it but I don't think the download worked. How can I tell if I am using Mountain Lion and how do I get help if the download was unsuccessful?
Click your Apple menu icon top left corner of your screen.
From the drop down menu click About This Mac.
If Mountain Lion is installed, it will say: v10.8
If not, launch the App Store. From the App Store menu bar click Store > Check for Unfinished Downloads
FYI .. for downloading Mountain Lion from the App Store, a high speed (broadband) internet connection is strongly recommended by Apple as noted here > iTUNES STORE - MAC APP STORE - TERMS AND CONDITIONS
If you need to reinstall OS X or repair the the startup disk Mountain Lion Recovery, that requires broadband access to the internet via Wi-Fi or an Ethernet connection. OS X is downloaded over the internet form Apple when OS X Recovery is used for reinstallation. -
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 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. -
