Reset macbook without login information
Hi!
I got a a2337 model macbook from ebay and it still has the original owners activation lock on it (the seller claims to have in turn bought it from someone else). I tried the "Erase mac" option. (It says that if you can not activate the mac, then you should try that option.) When I do so, it still asks for the login and password. Am I screwed? If I bring it to an apple center will they reinstall the operating system for me even without the receipt?
Thanks in advance for your help.
