HT201364 product distribution file
I can't seem to download Mavericks. The error message tells me, "We could not complete your purchase" and "The product distribution file could not be verified. It may be damaged or was not signed."
Any thoughts?
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 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 models. 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.

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 keep getting the message "The product distribution file could not be verified. It may be damaged or was not signed." Does anyone know what I can do to correct this so I can download OSX?
I have a MacBook Pro with all the necessary requirements.Here are a few things to try:
Restart your Modem and Router.
Reset iTunes Store Cache (iTunes Preferences, Advanced tabl)
Delete the App Store plists (close App Store first):
~/Library/Preferences/com.apple.appstore.plist
~/Library/Preferences/com.apple.storeagent.plist
To get to these,iIf you still have your user Library hidden, hold down the Option key and select Library from the Go menu in Finder. Otherwise, just go into your home folder, then Library, and then Preferences. -

Trying to upgrade to Mavericks but get The product distribution file could not be verified. It may be damaged or was not signed.
I have done Google and done the Var folder thing and deleted the folder with Apple store etc but to no availRemember: 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. -

"The product distribution file could not be verified. It may be damaged or was not signed." Why is that?
Disable anti virus software if installed.

Regards
Andy DicksonSeveral 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 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 Fusion Drive or 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.

what does this mean ?
The product distribution file could not be verified. It may be damaged or was not signed.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.
