Which version is recommended? 1.3 from St.Clair Software website or 1.2.4 from Apple App Store, sorry if this is a dumb question, but why are there two versions available concurrently, Thanks!

Running 10.9.1

Only costs 1.99 USD in Mac App Store!

Just bought it since my Time Machine drive crashed for not ejecting properly.

For the most part, Jettison works, but it isn't able to eject a disk if it's "in use." As gatovadio notes below, often what qualifies as "in use" is an app that is not actively reading or writing. There's no ability to quit apps, or to run an Applescript that could quit chronic offenders. A lot of the time I end up having to manually eject one of my disks. I'm going to give unDock a try, as the new version offers more features than Jettison, even if it doesn't (yet) trigger on sleep.

I just found that the oldie SleepWatcher is updated to work from 10.3 to 10.8. I haven't played with it but it should allow even more freedom than both these apps, with endless scripting possibilities.

It's not safe to eject a drive while there's a file open on it, even if you're not actively reading or writing to the file at the time (and OS X will not allow it). Think of it this way: If you open a spreadsheet in Numbers and then put your Mac to sleep, when it wakes up Numbers expects to be able to read whatever data it needs to refresh its windows, save changes, etc. If the file is suddenly gone, you've got a data integrity problem.

It would be a nice addition to auto quit apps which are in use by some disks (media players or wallpaper switchers which don't even require me to save my work before quitting).

I had a dismount problem with a external firewire hard drive, when it entered sleep, Jettison eliminated the problem completely, now I can let the computer go to sleep when ever it wants.

This works well as I often forget to unmount my drives before sleep. I wish it would also unmount my iPad but I gather that isn't possible.

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.
