You can't open the application "App Store" because it is not supported on this type of Mac.
Please see images bellow.
I've tried to reinstall OS X 10.9.1 update through apple website to try resolve this...but haven't had any success.
Any ideas?
Both the App Store and Preview icons in doc still remain unusable.
I can't complete any software updates....
MacBook Pro, OS X Mavericks (10.9.1)
