Hm, tried it again with latest snapshot.  GRASS.app starts GRASS in  
Terminal, and starts GUI in X11 Wish.  Quit GRASS in Terminal and GUI  
stays running in X11 Wish.  Any attempt to do stuff in GUI then gives  
Location not set error.

I looked at process ownership - Wish starts out with the GRASS shell  
as the parent.  After quitting GRASS with the Wish GUI still running,  
Wish now has launchd (process 1) as the parent.  Happens with both  
X11 Wish and Aqua Wish.  GRASS doesn't seem to be killing Wish, just  
letting it go on with its life.  hehe, some parenting and animal  
behaviours come to mind...

I've found an odd problem.  First, with X11 Wish (don't set  
GRASS_WISH or GRASS_TCLSH in .bash_profile), start GRASS.app.  GUI  
starts in X11.  Select mapset and start NVIZ from GUI.  All OK - NVIZ  
works normally and starts directly in NVIZ with no rasters or vectors  
selected.  Quit everything.

Change GRASS_WISH and GRASS_TCLSH to Aqua version in /usr/local/bin.   
Start GRASS.app, GUI opens in Aqua Wish.  Select mapset and start  
NVIZ.  NVIZ GUI startup dialog shows to select initial data.  Select  
something and Run.  NVIZ progress shows, then disappears.  No  
display.  NVIZ has a crashlog with something completely different  
from any previous crashes - it's crashing in G__open_cell_old.

BUT, while still in the Aqua Wish GUI, if I start NVIZ from the  
Terminal, it works.

So, now NVIZ doesn't work from the Aqua GUI.  But otherwise works  
normally.

Haven't tried Aqua NVIZ again, but thanks to Amilcar Challu, I've  
verified that NVIZ Aqua doesn't work on Intel Macs at all - it's not  
the graphics card difference.
