This thread is "Mac QGIS 3 GRASS fix, but I don't see anything that fixes the problem. Has anyone managed to get GRASS working in QGIS3 for OSX? I'm running the latest installer QGIS-macOS-3.2.0-1.dmg and it's still not working.
Also, we've put an inquiry in with Andreas Neumann about how to support (financially and otherwise) the creation of proper OSX installers that are stable enough to depend upon for research and deploy enterprise wide. We've not heard back and it's been about 3 weeks. Is there another venue for us to contact QGIS.org to try to get this properly funded so we can move on to work that matters, rather than installing and uninstalling non-working distributions?

The os.walk() finds the color file named "grass" before it has a chance to find the real "grass72" file at the top level of the grasspath. Though this is odd since it looks like os.walk by default should return a folder's info before it walks subfolders. I don't think a file check will help, since it finds a file from the returned files list. I do think the walking the whole grasspath tree is excessive. > On Mar 22, 2018, at 5:56 PM, Nyall Dawson <nyall.daw...@gmail.com> wrote: > > On 23 March 2018 at 08:47, William Kyngesburye <wokl...@kyngchaos.com> wrote: >> Well, it seems that running any GRASS Processing coughs up this error. >> Mystery to me, permissions are correct for the app, nothing should be >> writing to the app, and if it is trying that's wrong. >> >> The error doesn't help me try to figure out what's going on.
