Changing App Store Login We Have two Users on a 2013 MacBook Pro: 'A' and 'B'.
However, when User 'B' tries to log in to the App Store, the login prompt is already completed with User 'A' info.
Is it possible to have two Users log in separately to the App Store on one laptop?
What you see as 'already completed with User A info' is the auto-complete feature. You can change user in the App Store following this:


Open the App Store app
MenuBar > Store > Sign Out...
MenuBar > Store > Sign In...
Delete info in Apple ID and Password fields
Enter User 'B' info and press Sign in
