Hello this is my first post so i hope i do well at explaining! i just got a mac book pro 13inch it was working wonderfully till i downloaded this one program (add folder icons) then my computer crashed i went to the virgin mega store (where i bought it) and they were able to fix it. However now it takes a long time to boot up. so i did all the zapping the pram and nvram,and cleaning the system cache and all that stuff. I took it to the last resort and clean installed my system and it still boots up slowly !! i am really frustrated i thought macs were all that and im getting problem in the 3 week i got it!!!!!
