I get the following error,
"The update āiTunesā canāt be installed."
"The update could not be verified. It may have been corrupted during downloading. The update will be downloaded and checked again the next time that Software Update runs."
MacBook Pro, Mac OS X (10.6.8), iTunes 10.6.1(7)
What happens when you try it again, "the next time that Software Update runs"? (You can quit the current session and immediately select Software Update from the Apple Menu to run it again.)
I've tried the update 5 to 10 times over a period of days, thinking maybe there is a known problem with this update that will be fixed, hoping that it is not my system. I'm wondering if I update my OS to the latest if that will help, but I'm waiting for the latest latest to come out. But that "shouldn't" matter.
Another option is deleting iTunes and installing from scratch - something I've never done, and not sure what impact that may have on any saved info from iPhone synchs or maybe other impacts. Advice on that?
Instead, I would use the stand-alone installer from here
and try letting it do the installation (instead of Software Update). If your Mac has been running without restarting for a few days (or weeks), download the iTunes installer, then restart. Do the installation immediately after the restart. (That's actually how I usually run Software Update. When I see an update come up, I find a convenient time to restart. Then I run Software Update immediately after restarting.)
And you should update the OS to the latest bug-fix version. If it's currently 10.6.8 (as it says in your profile), I don't think there will be another release of Snow Leopard (other than security updates). Maybe you are referring to waiting until Mountain Lion comes out... š
The current iTunes should be fine with 10.6.8.
Before you try the stand-alone installer, you may want to use Disk Utility, select your startup disk in the sidebar, and run both Repair Disk Permissions and Verify Disk (on the First Aid tab). Don't be concerned if a lot of messages come up from Repair Disk Permissions, but if Verify Disk reports a problem, that should be resolved before doing anything else. This is just in case the "corruption" issue is cause by a more general data corruption issue.
The stand alone installer worked. Thank you! š
The Repair Disk Permissions did indeed have a lot of messages.
The Verify Disk said, "This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk." How do I do start up my computer with another disk? Is there some key combination to press during power up? I will look for my Mac OS X installation disc.
You should first back up your data. If you have been using the built-in Time Machine, that will serve as your backup. Otherwise, at the very least, you should back up your user data to another drive. Continuing to use the drive can make the problem worse over time. And trying to do a Repair Disk can sometimes make the problem worse, not better.
Insert Mac OS X installation disc. It should be the disc for the currently installed major release of Mac OS X. So if you currently have 10.6.8 installed, use a disc for installing Snow Leopard.
Start up with the C key held down. That will force startup from optical drive. You can also start up with the Option key held down, to get to the Startup Manager screen, then insert and select the Mac OS X installation disc.
When you get to Installer, go up to the menu bar. Under Utilities, select to run Disk Utility. Select your startup disk in the sidebar and go to the First Aid tab. Now that you are starting up from a different disk, you can use the Repair Disk command on your usual startup disk.
This is much more than I expected. I have all backed up (I think). Not sure about things like contacts and bookmarks. Have Snow Leopard disc. Hope it works...
The Repair Disk found two volume mismatches and they are fixed. Thank you for the help. Good experience.
Good news... Glad it was not something serious, that Disk Utility cannot repair. š
