Hey guys, sorry if this has already been posted. I can't exactly check.. without losing my sanity. I will keep this brief since every 5 characters I type, I stare at the pinwheel for 30 seconds. Ive tried everything. Safari and iTunes are killing my i5 processor. Fall 2010 17" MBP. How can I redo Lion without losing all of my music, movies and photos? Been getting worse.. now I have lost it. Thanks.
