[Qgis-user] How to enable GRASS7 in QGIS 2.16 on Mac?

[William Kyngesburye]

Loading GRASS data and using the GRASS toolbox are separate from using GRASS "algorithms" in the Processing plugin.

The Processing plugin needs to know where GRASS is (set in Processing options, but defaults to bundled GRASS 7), and runs GRASS commands in a separate process than QGIS (should not crash QGIS).

Loading GRASS data in QGIS needs no configuration of a GRASS path (this could crash QGIS if there is a bug or build problem).  Running GRASS modules does need configuration, but this also defaults to the bundled GRASS 7.  There is also a "general" GRASS option for the GRASS installation path, but this seems to default to the compiled GRASS location.  You can try setting this to the QGIS app:

  /Applications/QGIS.app/Contents/MacOS/grass7

If you still get a crash, a copy of the crash log would help figure out what's wrong.
