Hi Everyone,
All I got after upgrading to Snow Leopard from Tiger, was the stupid spinning beach ball - for everything i did. Open a window, spinning beach ball, open a file, spinning beach ball, write something, spinning beach ball....etc. I was really freaking out. My system is really powerful, i never get the beach ball even though i work on really large files.
Needless to say, I wasted 4 whole days troubleshooting, reading everything online about the problem, etc. Until today. I finally talked to an apple specialist who knew what to do.
I know this is not a real solution to the problem. More of a work-a-round...but i was fed up and it worked for me.
All you have to do is CREATE A NEW USER. Yes, that simple. Much easier than wiping your computer and doing a clean install which really has no guarantee to work anyways.
I really hope this helps people out with this problem. I couldn't be more relieved.
