A handy new feature of macOS Sequoia allows a mounted volume to self-eject once a process copying files from it ends. Here’s how to use it.
If you’ve ever copied a large file from a mounted .dmg file in macOS, you’ll know how annoying it can be to have to go back to the Finder to eject the disk once the copy finishes.
This is because the .dmg’s filesystem is in use during the copy. Finder holds the .dmg’s mounted volume captive as long as it is in use.
