Ok, my macbook is starting to scare me. I bought it in august, so ive had it roughly for 2months now. I've noticed its getting slower and slower to boot up each time i turn it on. i have 2 gbs of ram, so it shouldnt be slow, ive verified and repaired the disk too. I also have random software jams, especially safari, just closes for no reason. Any thought on what may cause this?
