Q: Error 20, Impossible to update my apps
Hello,
I am always getting this error when trying to update my apps
- First it says "An error occured while you tried to buy" and then "An error occured ... error 20"
Here are the steps I have already tried:
- Debug, Reset Mac App Store
- Sign-out Sign-in
- Restart
- Update to Mountain Lion
- Deleting ~/Library/Caches/com.apple.appstore
I think this crazy error is making me insane !!!
MacBook Pro (15-inch Early 2011), OS X Mountain Lion (10.8.2)

Here is the alternative solution that worked for me:
- Create a Second (temporary) admin account
- Update/Install your apps from the Mac App Store of this second admin account
- Done ! (The update and new apps are common to all users ! )
- Come back to your first Admin account. All your apps are Up to date !
