If you still need help...


Try here > Mac App Store: "An unknown error occurred (100)" when purchasing


If that doesn't help, 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/Cache.db


Click Go


Move the Cache.db file 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.pllist


Now here:


~/Library/Cookies


Click Go


Move the com.apple.appstore.plist file from the Cookies folder to the Trash.


Empty the Trash, try the App Store.
