Comment (by news24lor):
I tested the official versions of QGIS and GRASS.
I downloaded and installed QGIS 4 and QGIS 3 from the [https://qgis.org
QGIS] website, and GRASS 8.4 and GRASS 8.5 from the
[https://grass.osgeo.org GRASS] website.
In QGIS 3 and QGIS 4, under Settings → Options → System, I added two
variables for GRASS in the Environment section.
To use GRASS 8.4, I entered:
{{{
GISBASE /Applications/GRASS-8.4.app/Contents/Resources
GRASS_PYTHON
/Applications/GRASS-8.4.app/Contents/Resources/python.app/Contents/MacOS/python
}}}
To use GRASS 8.5, I entered:
{{{
GISBASE /Applications/GRASS-8.5.app/Contents/Resources
GRASS_PYTHON
/Applications/GRASS-8.5.app/Contents/Resources/python.app/Contents/MacOS/python
}}}
Both QGIS 3 and QGIS 4 work well with GRASS 8.4.
Neither QGIS 3 nor QGIS 4 works with GRASS 8.5.
There may be some issues
