[Qgis-user] QGIS3 macOS GRASS issues

[Alex Mandel]

Stace,

FYI, your post got buried as reply to a different thread, so some people
might miss it.

Looking at the error, it sounds like a classic python problem where
someone used spaces sometimes and tabs other times. What type of file is
grass74?
> TabError: inconsistent use of tabs and spaces in indentation
> File "/Applications/QGIS3.app/Contents/MacOS/grass/grass74"

I don't have a Mac so I can't test myself but I have some ideas at least
on that error. Also looks like it's be reported the bug
https://issues.qgis.org/issues/20705

Thanks,
Alex
