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 more...

What's New

Version 1.4.1:

  • The logic that Jettison uses for ejecting and remounting drives is now much more tolerant of errors.
  • Jettison's menubar icon is now compatible with OS X 10.10 Yosemite's "dark mode."
  • Jettison now offers to move itself to your Applications folder when you first launch it.
  • More information is logged to the Console so errors are easier to more...


  • OS X 10.6 or later
