[Qgis-user] GRASS dependency problem on OS X

Tue Mar 10 21:19:05 PDT 2015

The permissions are correct - and don't forget the other part of this
mystery, that if I use QGIS with a different user, GRASS works just fine!

This implies there's something wrong with settings or prefs for my user.

I've deleted/reinstalled QGIS, removed ~/.qgis2, removed the preferences
.plist - all I can think is that there must be some other configuration
file I'm missing?
