Edit: I see now that I posted this in the MB Air sectiion. This needs to be in the MB Pro one. Idk how to change that. I have been trying for a couple of days now. I restored a backup from my Time Machine. and everything was well and dandy. But now I forgot which password I had on the login screen of my Macbook. (Backup was from last April). So I had the chance to reset my password using my Apple ID and password. I've checked, checked and double checked. The logins work perfectly on my ipad. But it simply doesn't work on my macbook. I've tried everything. Even changing my apple ID password on a different device just in case I DID forget my Apple ID password/email. But I didn't. OSX 10.8.3 is in use right now. And my Macbook Pro is from Late 2012. I can only use the Guest User account. And nothing more. I am very frustrating. Is there anyone that can help me and knows what to do?!
