I can't update my MacBook Pro because I can't connect to the App Store. Safari and Mail no longer work.
I don't know what to do apart from to get hold of a copy of one of the latest operating systems on a USB drive and install from that. Even that might not get Safari and Mail working again.
I've tried to use support Chat but it is not accepting my device serial number!
Any ideas?
