Hi there, I've just purchased a new MacBook Air 11inch maxed and i have a few questions, if you can guide me please: - how can i know what model/rev is my actual macbook air and when it was made? - i heard some early version of macbook airs had some problems with their display. do you know for what rev that was happening? - how can i be sure that i'm reformatting right the battery? how long should i wait to charge? what should be the procedure? Thanks a lot!
