The first thing to attempt is restarting in Safe Mode, this will clear some caches. It's possible one or more has become corrupt. Once it has started navigate to 10.6.8 Update Combo and download and install per the directions. After it has installed if you still have difficulty re-starting, go to System Preferences - Startup Disk and make sure the internal HD is highlighted and click restart again and restart again in Safe Mode. Finally restart normally.
BTW I have asked the moderator to remove the serial number of your machine for your own security. Please DO NOT post private information such as email addresses, serial numbers etc.. to a public forum.

Question typed in subject space. Sorry!
Hi there Amy,
You may want to take a look at the article titled "Troubleshooting Mac OS X installation and software updates (Mac OS X v10.6 and earlier)"
There is a specific section that includes this information:
Software Updates for Mac OS X and Apple applications for Mac OS X are often available in different ways:
Software Update preferences
Standalone installer from Apple Downloads.
Try getting the software from a different source, or download it again.
Hope that helps,

I downloaded Mac OS X Lion and when I go to install, it says file cannot be verified, may have been corrupted during download. How do I determine if it is corrupt and how do I get a clean copy of Lion, since I have already paid for it?
Download again, move the existing file out of the applications folder first.
-
How can I solve this? Every time I have the option to update an application I receive the same notification: "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"
Can we eliminate one minor possibility: are you in the UK and using Virgin Media cable connection? I ask because the latest 'Superhub' firmware is corrupting large downloads for some people.

Latest update returns error " None of the selected updates could be installed. The update could not be expanded, and may have been corrupted during downloading. The update will be downloaded and checked again the next time that Software Update runs."
Which latest update? Details get answers. Rather than using SU, DL and install from http://support.apple.com/downloads/.

Sorry, for some reason you've posted this in the iPad forum .... Better results are to be expected in the LION one.

All Appstore and Mac updates Fail saying "...could not be verified or may have become corrupt"
Recently my Mac started to become glitchy so I decided to wipe the hard drive and reinstall my OSX Mountain Lion. After doing so almost all of my updates fail showing this msg "...could not be verified or may have become corrupt". Not to mention downloading updates take ridiculously long. I have 80mbps down and small updates say they could take up to 2 days. I wanted to try upgrading to the the newest OS however that also has the error msg…not to mention a 4 days estimated download!
any help with this would be greatly appreciated!
and yes I did set my date and time to automatic.Mavericks Download can’t be verified

When I download software updates, I continually get the message "The update “Compressor 1.2.1” can’t be saved.The update could not be expanded and verified. It may have been corrupted or tampered with during downloading. The update will be downloaded and checked again the next time that Software Update runs." What do I need to do? This seems to be blocking other software updates.
By twice, I mean is there at least two copies of the same Time Machine data? Backing up several times a day with Time Machine does not yield two distinct separate restorable sources. Only one is made.

can some one help me? I have been trying to update my MAC and it will not download because this message come up
(The update could not be verified. It may have been corrupted or tampered with during downloading. The update will be downloaded and checked again the next time that Software Update runs.)For anyone that comes across this. I managed to fix the problem. It had something to do with the date on my computer. Mavericks installer apparently does a date check of some sort and that is where the error is coming from. Open terminal and check the system date. It may be wrong. Another poster in the forums told me how to to check the date and change it. Click here for the link to the explanation. Be careful because the date is in a weird format.

I have not been able to install Max OS X Lion because in the process the following message was displayed:
"THE SOFTWARE COULD NOT BE VERIFIED. IT MAY HAVE BEEN CORRUPTED OR TAMPERED WITH DURING DOWNLOADING"
How can I solve this?
Note: I trashed the download and tried re-downloading but this effort was unsuccessful.Since writing my original post I decided to send the following message to Mac App Store Customer Support:
"I have had to download this file from the app store at least ten (10) times. I try to install the file but I keep getting the message "The software could not be verified. It may have been corrupted or tampered with during downloading."
I then delete the same file and try another attempt at a different time of day. Most recently following Apple Support's advice I contacted my ISP to clear the file cache but they could only clear my browser cache. I have deleted my com.apple.appstore. folder which contains app store cache, also com.apple.appstore.plist and tried again to no avail. I have wasted hours doing all this and I now want my money back please. You can keep this software update until you release it on disk like Snow Leopard which installed like a dream. I'm very disappointed with Apple that they expect the purchaser to do all the work trying to diagnose their software installation issue. Nice idea but poorly executed has been my experience."
I received this message which has confirmed my refund request:
Julia here from the iTunes Store. I understand that you received an error message and have been unable to install OS X Lion. I know how eager you must be to have this resolved, and I will be happy to help in any way that I can.
Please accept my sincere apologies for the frustration this download has caused. Since you were unable to enjoy this purchase, I have gone ahead and issued a refund. In five to seven business days, a credit of £20.99 should be posted to the credit card that appears on the receipt for that purchase.
If you have any other questions or concerns regarding this issue, please reply so I can assist you further. Thank you for being an iTunes Store customer.
Sincerely,
Julia
iTunes Store/Mac App Store Customer Support
Perhaps I'll wait for a disk to become available or see if a download to a pen drive at an Apple store is possible. -
Can't download the latest iTunes. A window pops up... The update could not be verified. It may have been corrupted or tampered with during downloading. The update will be downloaded and checked again the next time that Software Update runs.
Now, iTunes won't launch and can't be updated. Please help.
If I have lost my music collection I will be switching platforms ASAP. It is insane that Apple has updates seemingly every day for their products.I was in your same situation with 14 downloads and 14 attempts.
You have to make sure that your Mac is booting into 64 bit mode. You can make sure of this by going into System Preferences and scrolling down to 'Software' and making sure that you are booding with 64 bit Kexts.
If not, restart while holding the 6 and 4 keys down until you see the spinning gear wheel and try installng again.
BUT, what I also did was to go into Applications, click on the Lion installer, Get Info, and give yourself custom priviliges to Read And Write.
I did this simultaneously, and I don't know what function did it, but it worked for me, with no further downloads of the installer.
Good luck! -
I don't know if this is a Firefox problem so I ask, When printing how come it always prints so small I nearly need a magnifying glass? Is this caused by something else I may have set incorrectly? help please, from a very satisfied Firefox user
This only happens when I'm in my browser. Ex. when I'm on a site and I decide I like what I see and want to print it text that is, my printer always prints tiny. When I'm in Microsoft Word for ex. I print it and it looks like what I expect. So I don't know if somehow my printer got set to print tiny when on the web. If you can help me I would be most appreciative. Thanks again for your response.
