Jettison 1.8.1

Jettison automatically ejects external disks from your Mac before your computer goes to sleep.

Simplify those last few seconds when you grab your MacBook and run out the door. Just close the lid and Jettison will automatically eject your backup drive, iPod, or whatever is connected so you can safely unplug it. Say goodbye to “disk was not ejected properly” errors and waking your computer back up because you forgot to eject everything.

Jettison even makes sure that Time Machine backups and file server volumes are properly shut down before they’re removed. Your backups and shared files are safe and sound.

And what if you decide not to leave, and open your MacBook back up? Jettison will check to see if your drives are still connected and will mount them back on the Desktop if they’re there.

What’s New

Version 1.8.1:

  • Corrected a problem that could result in some disks failing to eject because macOS wasn't allowing enough time before going to sleep.
  • Added a setting to prevent Jettison from quitting Music, iTunes and Photos before ejecting disks. To turn this on, use this command from Terminal: defaults write com.stclairsoft.Jettison leaveAppsRunning 1
