HT201364 trying to download os x mavericks and i get an error saying "The product distribution file could not be verified. It may be damaged or was not signed." how do i fix this so i can update my new macbook pro?
"The product distribution file could not be verified. It may be damaged or was not signed."
please help! i want to update my computer!!!
"Update your new MacBook Pro"?
Well, if your MacBook Pro is new, it already has Mavericks installed and there is nothing to update.
Go to the Menu Bar, and click the Apple logo. Then click "About This Mac." Does it show OS X 10.9 or 10.9.1?
If so you are already running Mavericks.

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. -
Mavericks Update - Error message - The product distribution file could not be verified
Help!
Trying to download mavericks (from 10.7.5) as I have just had a new hard disk isntalled and need to start from scratch.
Wanting to re download iphoto but I can't as I need a newer OS so trying to download mavericks from the app store. My internet is very slow and keeps cutting out so I have tried a few times but it's not working.
Now I'm getting an error message - 'the product distribution fil could not be verified'
If anyone can help that would be great.
Or even let me know where I can get a copy of iphoto to suit OS 10.7.5 so I don't need to download a whole new OS.You're trying to download a 5 GB file. If your Internet connection is lousy, you won't have much success. Try another network.

Whenever I try to update my iPhoto program I get this error message "The product distribution file could not be verified. It may be damaged or was not signed."

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, or by a peripheral device.
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, 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 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. -

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. -

<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. -
I've seen a few threads on here about how to fix it and the ones I have tried do not work. To make things more complicated I have moved to Japan since buying this computer so I am not wanting to call Apple Support since it will cost me a ton. Any help at all would be greatly appreciated!
Press Shift key in boot, go to App Store and download

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?

Mavericks installer can’t be verified

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. -
How can this error be corrected? "The product distribution file could not be vverified. It must be damaged or was not signed. So can this error be repaired?

Another question can I operate laptop with other project while it is downloading?

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.
