Please note : darktable 4.8 is meant from macOS 12.5 and up (Monterey).
I do have 12.7.5 (lastest version for Monterey), Darktable has a forbidden sign and refuses to start.
This version is not made for Monterey anymore despite the documentation.
Edit: Use version for 10.14 & 11.0 compiled by @MStraeten
