User level: Level 1 (0 points)Automatically eject Time Machine disk after backup?
My Time Machine disk is on a dock, so it mounts whenever I connect. I solved the "forgot to eject" problem with a Folder Action script (backs up if due, then unmounts) — github.com/mous-design/backup-action. Is there a built-in way I missed, or a better approach?

macOS option to automatically eject the Time Machine disk when a backup finishes. Apple only provides the usual instruction to eject the backup disk before disconnecting it.
There are small utilities that monitor Time Machine and eject the volume only after a successful backup. For example, TMEject does exactly this, while BackupEject is designed specifically for MacBooks connected to a dock: it can start the backup when the disk is mounted and eject it when the backup completes.

Thanks! I couldn't find either of these, though. Do you have a link to TMEject or BackupEject?
