This is my second time around re-installing snow leopard - clean. Why is it so slow? The spinning whell comes up all the time, even for mundane tasks such as minimizing a window where I have to wait 10 or 15 seconds at a time. This time around I installed all the latest updates and iLife '09 - but its still as slow as ever. I also downloaded latest version of firefox. I uses a late 2009 Macbook Pro 2.53ghz 15 inch, and previous OSX flies on this machine. I'd like to go back to OSX Leopard but I can't cause I need the latest version of iPhone SDK which only runs on snow leopard. What's going on here Apple? Your OS is unstable and slow, and there's no acknowledgement from your site whatsoever!!
