Jettison 1.9.2
The second big thing in this release is a change to accommodate macOS Sequoia 15.4’s increased security around ejecting disks when your login account doesn’t have administrator privileges. I’m not sure why Apple made this change, but errors saying “Higher privileges required by Jettison” began occurring in 15.4. So Jettison now uses a helper application (which does require an admin password to install) so it can still eject your disks despite this somewhat nonsensical restriction.
Version 1.9.1 also improves error reporting when disks can’t be ejected. It uses additional diagnostics to catch situations where an app is keeping a disk busy and includes more information in the resulting error messages. It also preemptively terminates the system’s AMPDevicesAgent process, which can prevent an external disk from ejecting if it houses your Apple Music library.
The first issue hasn’t been a problem for me because I run an admin account. However, I’ve had lots of other problems with Sequoia being unable to eject volumes, and recent versions of Jettison seem to almost entirely fix this.
