at least with 3 different M3 and a M3max machine in the local apple store my arm64 build from current OSX Build - #754 by MStraeten runned fine:
- download it
- run from terminal:
xattr -c ~/Downloads/darktable-4.7.0+1237~gfdedc3dae2_arm64.dmg
- double click the dmg
- run from terminal:
/Volumes/darktable/darktable.app/Contents/MacOS/darktable --configdir ~/.config/darktable_dummy
if there’re issues then attach the output as a text file
