Add support for build from source on macOS, see #3683

Many thanks for looking at this and developing this PR.

Just one quick comment - changing existing logging / adding additional logging for differences between inotify and what MacOS uses such as this:

IMHO it would be better to use:

version (OSX) {

} else {

}

Then the logging for the platform being targeted is correct.

Also, there is a LOT of work going on at the moment for smoke testing / CI testing. It would be great if you could, in the first instance, add a yaml file for MacOS build .. to ensure the build is working correctly.

Unfortunately due to how the CI Secrets work, adding a smoke test to your PR is not going to work, but I can add one for MacOS shortly thereafter.

@xcodebuild
Another item - please can you keep your changes in this PR to supporting MacOS.

These 3 commits seem to be potentially a workflow or related to a potential bug with how the internal accounting is done - id rather those fixes be attributed to a bug report, with the correct evidence, than have this added in here.

offending commits (thus far):
