After "upgrading" my mac from os 8.5.1 -> is 8.6, I had nothing but major headaches and depression. Tons of freezes and quit outs. I tried reformatting my hard drive and reinstalling EVERYTHING... but to no avail. Then I got Extension Overload and voila!!! It helped me turn off all of the unnecessary stuff and my life is total bliss. THANK YOU E.O.!!!
