This is in preparation of merging
https://github.com/zed-industries/zed/pull/47322, because our MacWatcher

Note: Release candidate 9 for Notify was created two days ago which
means that a new version is coming out soon. We should update to v9 once
it's released to include bug fixes from upstream.

Release Notes:
