Jettison automatically ejects external disks from your Mac before your computer goes to sleep and remounts them when it wakes.

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.

What's New:

Version 1.9:

• Jettison now prompts for Full Disk Access permission in System Settings > Privacy & Security to ensure that it can remount USB drives.
• When a disk can't be ejected because an app has files open on it, the error message reflects this accurately and the "Quit" button will reliably quit the offending app.
• If you've included disks in the "Don't remount these disks" list in Jettison > Settings > Options, those drives will also be unmounted after Jettison launches.
• Cryptexes, iOS simulators and other disk images used as part of system operation are no longer displayed in Jettison's menus.
• Jettison will correctly handle encrypted APFS volumes that are automatically unlocked by the system.
• Multiple "trial period expired" warnings will not be displayed at once.
