While running on github actions we very often run into the following error:

Exit code: 16. Command failed: hdiutil detach -force /dev/disk2
hdiutil: couldn't eject "disk2" - Resource busy

hdiutil: couldn't eject "disk2" - Resource busy
  failedTask=build stackTrace=Error: Exit code: 16. Command failed: hdiutil detach -force /dev/disk2
hdiutil: couldn't eject "disk2" - Resource busy

If I rerun it then it generally passes but that wastes times.

I don't think we have a way for determining if the resource is still busy, we simply can't move forward with the rest of the build process. We already retry ejecting the dmg 3 times.
