Sorry, should have remembered all that.  
Uh, I'll save you a little time and admit that I've got an integrated Intel GMA 950 graphics chip, which I guess is probably my problem.  I'd missed the part of the release announcement that said that wouldn't work until I went looking for the Windows version a minute ago. And saw it needed a dual core, so that's out too. Ah well!  So that's probably the issue; I guess you guys upped the graphics more than FS2_Open has (I can run that perfectly).  
Just in case that's NOT the issue, I'm running Mac OS 10.6.8, 2.16 Core 2 Duo CPU, 1GB RAM.  Log is attached.  
Guess I need to upgrade soon.
