I am running a 17" 2008 MBP with 6 Gb of RAM. MY initial feeling is the the OS is slower (as in beach balls spinning) and definitely boot up is slower, Firefox is slower. I have turned off natural scrolling but the system seem 'sluggish'.
May have to rewind /reload by backup of 10.6.8
Suggestions are appreciated.
