as far as just working...snow leo mostly behaves....disabled spotlight temp....was a cpu hog...and had to quit quicklookhelper manually ...that got my cpu usage back to normal...until the next kernel fix anyway...damn installers are annoying tho...been using pacifist some for generic installs that fail...but systemupdate downloads and installs stuff fine...every day it gets a little bit better...i have an apple keyboard... if i use the volume keys osx will either log me off or ...reboot...lol
