Whenever I try to update anything through app store, I just get 'waiting...' appear in the top right of the update box. The word 'update' is also greyed out so I can't click to start again. I've had this issue since I bought my mac last month. I need the loops that are available for garageband (1.0) and the new OS update (10.8.1) - help!
MacBook Pro, OS X Mountain Lion (10.8)
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
Click Go
Move the Cache.db file from the com.apple.appstore folder 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.plist
Now here:
~/Library/Cookies
Click Go
Move the com.apple.appstore.plist file from the Cookies folder to the Trash.
Empty the Trash, launch the App Store and try updating.
I did exactly as you said, but then went out so I shut my mac down. I tried updating again when I got in and it worked first time, thank you!
