[GRASS-user] Mac display problems

[Shaun Langley]

I recently tried to install Grass 7 on my mac, but removed it after realizing it didn't work.  I did not think I had made any changes to my Grass 6.4 installation.  However, something broke in the process and now I cannot use the GUI.  If I call g.gui, I get the following error:

GRASS 6.4.2 (kenya):~ > g.gui
Launching 'wxpython' GUI in the background, please wait ...
Traceback (most recent call last):
