From my understanding, with the new APFS system for macOS, the Recovery volume mounts itself briefly when it checks for updates; however the Recovery Volume on my MacBook Air is still mounted in
/Volumes after finishing checking for updates:
I could simply unmount the volume as if it were a external USB or restart my computer to unmount it, but I don't know why Recovery is still mounted after it has already checked for updates. Has anyone else experienced anything like this before? What can I do to prevent this in the future?
