hi i bought my macbook in februray its the new unibody model, well its been working like dream
till almost a month ago, i downloaded about 3.1 gbs of music onto it and it was working ok
, well now that i removed everything off the internal memory its running so slow
!! my safari got updated and everytime i go to a website is see that blue bar lag to the other end
, can anyone help me pls, i bought a 1tb external HD to keep memory free in the macbook to keep it from slowing down but its still slow .i am really considering selling this and getting an hp computer if i cant fix this, cause i paid nearly 2k dollars for the laptop
and i dont really wanna get rid of it but i dont like slow computers specially if they are high end ones it contradicts itself, well any help will be much appreciated thanks!!
