[Qgis-user] GRASS dependency problem on OS X

[Howard Frederick]

Processing algorithms for other providers work - tested R and SAGA at least.

The dependency error is thrown the moment I try to open any GRASS tool, and
the tool dialog never appears - so there is no opportunity to even try to
run any GRASS algorithm!

Error dialog:
Missing dependency. This algorithm cannot be run :-(
This algorithm requires GRASS to be run. Unfortunately, it seems that GRASS
is not installed in your system, or it is not correctly configured to be
used from QGIS

with QGIS
