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. -

<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. -

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. -

When opening Windows 7 I'm receiving the following message The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll.......I have never rec'd this before............I have a iPhone and iPad...............How can this be corrected without interferring with the information on my computer? Thanks
With Windows Explorer, navigate to your C:\Program Files\Common Files\Apple\Apple Application Support folder.
Copy the SQLite3.dll that you should find there, navigate to the nearby Mobile Device Support folder, and Paste it in there also.
Reboot and see if all is well
In case that your OS is Windows 7 (64 bit)
1. Open windows explorer, go to location C:\Program Files (x86)\Common Files\Apple\Apple Application Support
2. Copy file "SQLite3.dll"
3. Open new windows explorer, to to location C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
4. Paste file "SQLite3.dll" to the location.
5. Reboot your computer, it should not display that message, it should be clear.
Good Luck -
I am trying to update my iPhone but it seems that I have to many photos and music because I received the following message: The iPhone could not be updated; this device is not elegible for the requested build. Does anyone know how to fix this?
You have to delete the corrupt back-up so iTunes can at least back-up the current data on the iPhone and then restore it. Search these forums, there a several good posts on how to delete the corrupt back-up.

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. -

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. -
Good evening .. I'm with my problem no9 lightroom. I was open and gave the following message: The module was desabilitado.Renove reveal your subscription to reactivate module reveal. But it's all right with my signature.
Heya, Jonathan. Welcome to Apple Discussions!
Congratulations, and welcome to the fun-filled world of kernel panics. Yup, that's the text in the gray box you're getting.
The good news is you don't necessarily have to reinstall Mac OS X. If you have access to another computer and a FireWire cable, you can reinstall the 10.4.3 update, and everything should be groovy.
* Connect the two computers via FireWire cable. Your iBook should not be on yet.
* Boot up your iBook and hold down the 'T' key as it starts up. The iBook will enter Target mode.
* Download the Mac OS 10.4.3 update on the other computer.
* Run the 10.4.3 updater as normal, but select the hard drive of your iBook when you get to the list of available volumes.
Failing that, you can reinstall Mac OS X on your iBook from your install DVD. When you select your volume, make sure you click on the 'Options' button and select 'Archive and Install'. You'll retain all your personal files and network settings, but you might have to reinstall applications, haxies, etc. -
When I attempt to log on to I tunes I get the following message:
"The registry settings used by the I Tunes drivers for importing and burning CDs and DVDs are missing.
This can happen as a result of installing other CD burning software. Please re-install I Tunes."
To my knowledge no new software has been installed. I have tried un-installing and re-installing I Tunes but I still
get the same message.
Can anyone offer any suggestions? Do I need to download a new driver?
Bill MartinI can get down as far as step 11 but it shows nothing about upper filters and when I type on "If the Upper Filters entry is missing follow these instructions" nothing happens
Do you mean you can't see the instructions on what to do if there is no UpperFilters entry?
If so, here's the relevant instructions for that step:
On the right side of the Registry Editor window, right-click the UpperFilters entry and choose Modify from the shortcut menu.
Right-click the empty white space within the right-hand portion of the Registry Editor window. From the shortcut menu, choose New > Multi-String Value.
Name this new value "UpperFilters" (without the quotes). Then, right-click the newly created UpperFilters entry and choose Modify from the shortcut menu.
