I can't seem to download anything from the App Store. I get this message when I enter my username and password:


There was an error in the App Store. Please try again later. (100)


I have tried many times over three days and the same thing happen. I have quit , restarted, reentered everything.

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.
