Jettison Download 1.9.7 for Mac Overview

Jettison is a menu bar utility for macOS that automatically ejects external discs before a Mac goes to sleep and remounts them again when the Mac wakes back up (if the drives are still physically connected). And it’s a very real problem that Jettison solves, albeit a simple one: if you don’t unmount an external drive before unplugging it, you can end up corrupting the drive and losing data, over time. Jettison removes the need to remember to do that every single time. Specifically, Jettison handles the safe ejection of Time Machine backups and file server volumes, protecting backups and shared files from corruption. Jettison lets users customise what sorts of discs it handles, including or excluding specific drives as needed, and the app sits quietly in the menu bar, offering quick manual controls to eject all discs at once or handle individual drives on demand. Keyboard shortcuts are available for ejecting, sleeping and remounting. The assigned shortcuts are shown in Jettison’s menu for quick reference. The app also correctly hides system volumes that shouldn’t be visible (such as the Update volume on recovery discs, or the Macintosh HD boot volume) by reading directly from APFS metadata, and gives unformatted drives that don’t already have one a consistent “Untitled” name. The latest version on MacUpdate is 1.9.7, with recent improvements including consistent “eject” language throughout the UI (replacing inconsistent “eject” and “unmount” language), a fix for mounting encrypted volumes on non-APFS discs, and better handling of situations where macOS incorrectly reports that a drive failed to eject after it actually succeeded. Jettison is a 4.6MB download that requires macOS 10.9 or later, is a Universal Binary for Intel and Apple Silicon Macs, and is paid shareware (around $4.95 to $8.34 depending on the source), with a free trial available before purchase.

Key Features

Eject Automatically Before Sleep Automatically ejects external discs when your Mac starts sleeping so you don’t have to manually unmount each drive before closing the lid. Auto Remount on Wake Checks for any drives previously ejected that are still physically attached when the Mac wakes up and remounts them back onto the Desktop automatically. Time Machine and File Server Security In particular, it ensures that Time Machine backup volumes and file server connections are correctly dismounted, safeguarding backups and shared files from corruption during the transition to sleep. Customising Drive Handling Choose what drives to include or exclude based on personal preference, not some blanket rule for all that is connected, or deciding what kinds of discs Jettison handles. Manual Controls Menu Bar Manual controls from the menu bar: Quickly eject all connected discs at once from the menu bar, or eject and remount individual drives on demand without opening Finder. Customisable Keyboard Shortcuts Assign custom keyboard shortcuts for eject, sleep and remount. The keyboard shortcuts you assign are displayed right in Jettison's menu for easy reference. Smart Volume Concealment System It reads APFS metadata directly to properly hide volumes that should not be visible to the user, such as the Update volume on recovery discs or the Macintosh HD boot volume. Volume Naming Consistency Names unformatted or pre-formatted flash drives that don't already have a name "Untitled", keeping the volume naming consistent with standard macOS behaviour. Encrypted Drive Support It properly locks encrypted sparsebundle disc images when they are ejected and gives clear instructions for resolving situations where the password to an encrypted disc is not present in the keychain.

How to Use Jettison Download 1.9.7 for Mac

Step 1: Jettison For macOS 10.9 or later, download Jettison from macospace.com. Step 2: Install and run Install the app, and launch it. Let it sit in the menu bar. Step 3: Configure the drives to be managed Choose which types of external discs Jettison should manage, optionally excluding or including specific discs as you like. Step 4: Configure Your Keyboard Shortcuts (Optional) If you want quicker manual access than the menu bar can provide, create custom keyboard shortcuts to eject, sleep and remount. Step 5: Close Your Lid As Usual Just close the lid of your MacBook, or let your Mac go to sleep and Jettison will automatically eject any external drives connected at that time. Step 6 : Disconnect Safely.jpg You can confidently unplug your external drives once ejected, knowing that you have bypassed the “disk was not ejected properly” errors and potential data loss. Step 7. Re-open & Re-connect When your Mac wakes up, Jettison checks to see if any of the previously-ejected drives are still connected, and if they are, it automatically remounts them. Step 8: Utilise Manual Controls When Needed You can always manually eject all discs at once with the icon in the menu bar, or deal with a specific drive. Step 9: Use Encrypted and Network Volumes Use Jettison’s built-in handling for encrypted disc images and network file server volumes, troubleshooting password or unlock issues as described directly within the app.
