I'm not sure if it's just me (and the several people I know with macs) but 10.6.2 seems to be a bit of a disaster. I have a 17" unibody MBP and have been loving it until I upgraded to 10.6.2. Now I get beachballs everywhere, mostly in Safari and Excel, but all over the place really. Certainly never had any problems like this in 10.6 and 10.6.1. Is anyone else experiencing anything like this? My co-worker has the exact same model MBP and is experiencing the same thing, so I'm not sure if this is specific to our exact model of MBP.
