Hi, my mac pro became really slugish and I don't know why. I ran macscan and virus scan for mac from mcafee but it didn't find anything (well, 13 tracking cookies which i removed). I sometimes get lag before i can write in any field (like safari etc.). I have Early 2008 with 8gb ram and I've had this configuration since february. Internet is becoming really slow (usually, loads 75% and then it takes ages to load up the rest). Any idea what could be causing this strange behaviour? It really drives me crazy especially when I try to do simple task.
