Replaced Logic Board w/ Used, Can't Log In
I replaced my dead late 2011 logic board with used mid-2012. Now I can't log in, I'm assuming because the serials are different. It says:
"You are unable to log in to the user account 'UserName' at this time.
Logging in to the account failed because an error occurred."
The internet tells me changing my serial is close to impossible and I can't seem to find out if reinstalling OS X will make a difference in this situation.
Is there a way to still make use of all my apps and software even though they are linked to my old serial? I backed up a day or two before the board died (just had a bad feeling... I'm glad I did!)
What do I do to make use of this very lovely screen saver machine?
