Where can you find out to whom a given Mac is registered?
Is there a place in the OS that we can see to which person the OS is registered to?
Solution 1:
The registration information that you enter when you setup OS X is stored in a hidden plist file in the system.
That data is stored the file /var/db/.AppleSetupDone if you run the following command in terminal you should be able to see that information:
sudo cat /var/db/.AppleSetupDone
This will show you the information entered. You will need to modify this information with a plist editor. For warranty claims Apple will know who registered the machine for AppleCare.
