Jettison 1.5 fixes issues on El Capitan, improves speed and reliability.

This update is FREE if you've purchased a license for Jettison.

If you bought Jettison from St. Clair Software, just download version 1.5 and replace your existing copy.

If you purchased Jettison through the Mac App Store, please run this version of Jettison once BEFORE you delete or overwrite the old copy of Jettison in your Applications folder. If Jettison is still telling you your trial period is over, please follow these instructions.

What's new in Jettison 1.5

  • Fixed a crash that could occur when waking from sleep.
  • Improved remounting of SD cards when running on El Capitan.
  • Updated handling of Mac App Store receipts to accommodate expiring receipts (details here).
  • Added Eject and Mount menus so you can eject and mount individual drives.
  • Revamped volume identification, ejecting and remounting so it's faster and more reliable.
  • Jettison will now eject disks when the screen goes to sleep if the whole computer is also set to go to sleep shortly afterward. This resolves some "not enough permission" errors that were preventing it from ejecting drives when the screen was locked.
