Of course I got my new 2.4 macbook for christmas... What are the first things I should do? I'm calibrating my battery right now, and then I want to reinstall the OS later to get rid of everything I won't use. Will I have to calibrate it again after? And are there any ways to drain the battery faster? Do I have to stay on the macbook or can i just leave it and let it sleep? Thanks! And Happy Holidays!
