I opened GarageBand for the first time, to find that most of the loops required me to download the Apple Loops from Software Update. I agreed to this.

The App Store opened and gave me the option to install the update from Updates - I clicked Install and waited for the download to complete. It did, and then the installation began.

About half an hour later, the update is stuck on (Installing - Calculating...) This doesn't seem normal - the last time I installed the Loops, they were done in about ten minutes.

Force quitting and re-opening the App Store doesn't help, nor does a reboot. When I open the App Store, the update is still at the same process.

Is there anything that I could do to get the update to finish installing?

Here is a screenshot of the App Store in this state: The App Store in the state that I have described.

In an act of desperateness, I managed to fix the issue by doing the following:

  • Deleting /Library/Updates
  • Doing sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate.plist RecommendedUpdates ; sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate.plist DidRegisterLocalUpdates in a Terminal
  • Restarting the Mac

The update is redownloading now. Thanks everyone for the help!

EDIT: Interestingly, before I tested these steps, I found the update ready to install in /Library/Updates, however when I tried to install the PKG file, Installer claimed that another installation needed to finish (?). Deleting it and restarting fixed the problem.

Try deleting the cache located here:

~/Library/Caches/com.apple.SoftwareUpdate/

And the prefrences plist, here:

~/Library/Preferences/com.apple.SoftwareUpdate.pIist.plist

And start the application again. It should have flushed whatever updates that got stuck.

That didn't work. I deleted the Caches file (and /Library/Preferences/com.apple.SoftwareUpdate since there wasn't one in ~/Library/Preferences) and opened MAS. However, when I clicked Update, the update restarted again from Installing - Calculating. –  Faiz Saleem Feb 18 '13 at 13:17

I want to comment on Emil's answer but it appears I don't have the cred to comment.

I just wanted to add that I had a similar problem updating xcode. Simply clearing the cache and restarting App Store worked for me.

rm -rf ~/Library/Caches/com.apple.SoftwareUpdate/
