Upgrade from what OS?My system - the one described in the first post - can't do the 10.8.2 upgrade. Looks like the end of the line for it.
If you have any version of 10.8 it is not your system....mine is Mid 2010 2x2.4 GHz Quad-Core Intel Zeon 32 GB memory ... handles 10.8.2 as it did 10.7 etc etc......
I assume that any Intel Zeon will handle the upgrade.
Check this out...seems like a FUBAR report to me.
S2-P files with multiple layers at 400MB are no problem.
