Running Mavericks 10.9.4 on a MBP Air and trying to update to 10.9.5, the software updater runs a list of several updates, including EFI and bluetooth firmware updates then I get an "Invalid Apple ID and e-mail" msg and cannot proceed. I know the ID is correct.
Should I create a new Admin user, enter another known to be valid Apple ID and e-mail to do the updates and afterwards erase that User?
Any other suggestions?
