So I got my macbook a few days ago and it is amazing. No problems to speak of. I am still getting used to OSX but I am really likeing it. Now it is my first week and I need to calibrate my batter. You need to go from fully charged to fully drained and it is taking forever. I have been surfing the internet for atleast 4 hours, watched a lot of youtube, so I know this battery is a tough little cookie, but is there a way to drain it faster? Do I need to drain it all in one sitting? Can I spend two days draining my battery?
