What's new in Jettison 1.9.6

  • Jettison includes an option to display the number of ejectable disks next to its menu bar icon.
  • Error messages include the name of the offending process when something is preventing a disk from being ejected.
  • macOS 26.4 aggressively remounts disks when waking from sleep. Jettison prevents that for disks selected in its "Don't remount these disks" setting.
  • Some system processes (QuickLookSatellite, mds_stores, systemmigrationd) can prevent disks from being ejected. To work around the problem, Jettison can terminate them before your Mac sleeps. Use this command in Terminal to enable this:
    defaults write com.stclairsoft.Jettison terminateSystemProcesses 1
  • Remounting network volumes works reliably even after a volume has been disconnected unexpectedly.
  • When you remove a keyboard shortcut, that is correctly reflected in Jettison's menu.
  • Fixed a situation where the progress window could get left on screen.
  • The Fn (globe) key can be used in keyboard shortcuts.
  • Added support for volumes mounted over NFS.
