I want to use GRASS 7.6 with QGIS 3.10 installed on my Mac (10.13 - High Sierra).

I have installed QGIS 3.10 for Mac via this link : https://qgis.org/en/site/forusers/download.html I have installed GRASS 7.6 for Mac via this link : http://grassmac.wikidot.com/downloads

QGIS and GRASS both work separately, however when I am unable to use GRASS via QGIS. After activating the plugin in QGIS, I do not have access to any of the features (New Mapset, Open Mapset, etc.). Accessing at Plugins > GRASS > GRASS Options > General, I get the following error message :

Currently selected GRASS installation is not valid

I have the application located in my Applications directory.

What are the steps that I should do to be able to use GRASS via QGIS?

  • Try /Applications/GRASS-7.6.app/Contents/MacOS/Grass

They announced in the QGIS github (see issue : https://github.com/qgis/QGIS/issues/34721#issuecomment-592090316) that the plugin was abandoned and that GRASS should be used directly via Processing > Toolbox > GRASS
