Mac Pro freezing since 10.8
I have seen all of the other threads. I have tried everything recommended in them, from PRAM resets, to removing the prefs.plist.
Erased the dedicated HD that holds boot + Apps, reinstalled 10.8.3 freshly dowloaded, clean install from square 1 on a reformatted drive. Running the machine with no apps except system level plus Mail plus Safari, I still got system hangs. For no reason the finder becomes mostly unresponsive. Dock won't work, beachball, can't force quit.
So, since I wasted my time and needed to get back to earning a living as a self employed person, I re loaded all software fresh from fresh downloads and have been putting up with the random lockups and freezes.
It seems, maybe, Mail is to blame. Happens when I'm running mail, accessing mail, pointing to mail on the dock.
I've run hardware tests, removed the other 3 internal HD's, removed the two BDR burners, dug up and installed the old few-gigs of ram that were original to the machine ... no luck.
If there is anything new that I've missed, I'm grateful for your input. If anyone is listening, there is an issue as evidenced by the many threads and responses.
I'm sorry I ever left 10.7.3, which is humming along nicely on my Mack Book pro and an iMac.
