Major issues here please I can use all the help I can get. My MacBook Pro 13" Unibody Aluminum is booting in safe mode everytime i I restate. Someone has advised my shift key could be stuck? How the he'll could that have happened? It's only a few months old, I just upgraded hard drie. My trackpad was running funky before that. My keyboard was acting wired, only symbols showed up. Now nothing is going right?
