MacWorld •••• (4 stars!) : Jettison automatically ejects external disks before your Mac sleeps and remounts them when it wakes. ** PLEASE TRY THE DEMO ON OUR WEBSITE TO MAKE SURE JETTISON WORKS WITH YOUR DISKS **
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.
And what if you decide not to leave, and open your MacBook back up? Jettison will check to see if your drives are still connected and will mount them back on the Desktop if they're there.
What's New in Version 1.2.4
Corrected issues with Mac OS 10.8. Please see our website for a demo version, additional updates and SD card support.
Eliminates "Improper ejection" Error Messages
I'm among the mass of Apple users who experience "Improper ejection" error messages almost every morning for my two external USB drives. Having followed this issue for over 2 years in various Apple Forum discussions, no one, including Apple, has come up with a solution for this irritating and sometimes drive damaging issue… until now.
As some of you here have already reported, since installing Jettison, I have not seen the infamous "improper ejection" error message. Jettison does, automatically without any effort on my part, exactly what the developer says: "eliminates the hassle of manually ejecting external drives before you put your MacBook to sleep and remounting them when it wakes." By automatically unmounting my two external USB drives each night when my Macbook Pro goes to sleep, Jettison is eliminating the opportunity for Apple's flawed USB power management system to improperly eject my external drives. As soon as my computer wakes up, Jettison quickly remounts the external drives. And, most importantly, Jettison has NOT caused any conflict with my Time Machine backups or my SuperDuper clone backups (three of which are scheduled to run automatically at 1:00am every night).
For me, this is another great utility app from St. Clair software. (Default Folder is another "must have" app from this developer)
Jettison no longer works under El Capitan
This was a wonderful solution to a problem in Apple’s OS that is has never seen fit to address. Unfortunately, it no longer works. My LaCie 4TB drive, used for Time Machine, recursively tries to access the system while in sleep mode, despite being ejected by Jettison. The resultant error messages bring my 24 GB IMac to its knees and force a reboot. I hope that Jettison is able to address this problem, evidently introduced in Apple’s latest software update. Until then, I would avoid this product.
simple yet effective!!
You saved my life!! I can't tell you how simple this program is yet it fixed this huge headache I was having with my drobo unproperly ejecting every time I put my computer asleep. It has lead to countless hours at the Apple store and on the phone with Drobo support to no end. UNTIL…. I found your simple app. Problem solved! Thanks so much!!
Keep up the good work!
