The software could not be varified.it may have been corrupted or tempered during downloading

i have already purchase mac os x lion .it was now saved in appstore on my mac.but i could not able to install it.

The file may have been corrupted when you downloaded it, go to Applications and find the installer for Lion. Trash it. Restart App Store, it should show up for Install. Re-download it. and try and re-install it.
Make sure you use the same apple ID account and pass word as before.

Which latest update? Details get answers. Rather than using SU, DL and install from http://support.apple.com/downloads/.

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,

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.

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.

I am trying to update Mac software. but each time I download Compressor, I get a message that the update cannot be saved because it may have been corrupted. What should I do?

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.

When I go into outlook I and hit a new message and hit th "To" button, I get the following error message: The address list cannot be displayed. The contacts folder associated with this address list could not be opened; it may have been moved or deleted,

to continue: For information on how to remove this folder from the Outlook Address book, see MSOffice Outlook help. I also get an error message when I go to tools and hit the address book there. This crap is frustrating!

Hi,
Based on your description, I suspect that your proxy is in internet zone by default, so it cannot use credential
which has been recorded in window credential management. I suggest that we add
proxy server into “Local Intranet” zone via GPO to see if it can solve your problem.
Let me know if it works for you. Thank you.

I'm getting this when trying to navigate to the InDesign forum. Is an update in progress?
I can navigate to a post I made last night through my "Your Stuff -> Discussions" link but if I try to go to the forums from the main Adobe Forum page list, then click the InDesign link to see the forum as a whole, I get the error in the title.
I've cleared my cache and restarted my browser just in case but I've had no luck.

I see the same thing in a Mac and a Win machine. In my ignorance, I would guess that the problem may be related with this:

The software could not be verified

I downloaded lion from itunes, when i go to install it i get an error message that states "the software could not be verified. it may have been corrupted ot tampered with during downloading

I encountered the same error "…can't be verified…" error on my 2010 MBP too. Tried six times and finally I could get it installed. Here's what I did:
Went to "Users & Groups" in System Preferences, checked that the Apple ID specified for the current user is the same Apple ID I used in the download purchase of ML from the App Store.
Rebooted in Safe Mode.
Went to Disk Utility -> Repair Disk Permissions
Downloaded ML at midnight (and the download was significantly faster!)
Rebooted in Normal Mode.
Ran the ML Installer.

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. No iTunes now.

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!

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.

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.
