Hi, I was happily using 10.6.7 until I upgraded to 10.6.8. After THE upgrade to 10.6.8, my mac is running SUPER slow!!! I have 50% of hard disk space so it shouldn't be a problem. I ran Repair Disk Permission, and Verify disk etc but no luck. Everything is running real slow - Mail, internet browser, ITunes, Finder everything - it takes minutes to load anything. All I see is the spinning rainbow wheel!!!! Please HELP! To get back to pre-upgrade speed, should I reinstall Snow Leopard or should I go for Snow Lion upgrade???? Any suggestions please????
