Here are some questions and problems that people often encounter when using Jettison.
Before consulting this list or contacting us, please make sure you
are using the latest release of Jettison, version 1.2.4.
If you have a problem that is not addressed here or feel a question should
be here but isn't, please send mail to firstname.lastname@example.org
What version of Jettison do I need if I'm using
Mac OS 10.8 Mountain Lion?
Make sure you have version 1.2.3 or higher if you're running Mountain Lion.
Unfortunately, even with the latest version, Mountain Lion prevents Jettison
from playing sounds right before the Mac goes to sleep. After working for two
weeks with Apple's Developer Support engineers, they've come to the conclusion
that there really isn't any way to make Jettison's notification sounds work
in Mountain Lion. Fixing this will require changes to OS X. We've filed a bug
with Apple to document the problem, but don't know when it will actually get
In the meantime, Jettison does work correctly with Mountain Lion except for
its notification sounds.
After I put my Mac to sleep, I hear a loud
"gong" sound - what does that mean?
Jettison makes that sound to let you know that it couldn't eject one of your drives. We chose to use a sound because the lid on your MacBook
may already be closed, so you might not see a regular error message. When you hear this sound, you'll have to open your computer back up and
quit whatever application is using that drive so it can be ejected.
Why can't Jettison eject one of my external
This happens when an application is accessing a file on your external drive. Because the application will expect the file to still be there when
your Mac wakes back up, Mac OS X won't let Jettison eject the drive. To fix this, you need to determine which application is using the drive and
either close the file(s) that are on the drive or quit the application completely.
Why is Jettison more expensive to buy directly from St. Clair Software than through the Mac App Store?
Unfortunately, our payment processor requires a minimum total sale of $4.95
so the single-copy price of Jettison has to be $4.95. However, it's only $1.95
when you buy Jettison with any other St. Clair Software product. So if you're
buying Default Folder X, App
Tamer or HistoryHound, you can add Jettison for
less than $2.00! A link will automatically appear at the bottom of your cart
when you purchase any of our other products.
I bought Jettison through the Mac App Store. Can
I upgrade directly from your web site?
Yes, just download the latest version of Jettison here.
Before copying the
new version to your Applications folder, however, please double-click it to
run it once directly from the disk image. Jettison will
make a copy of your App Store receipt (which is embedded in the Jettison application
that you downloaded from the Mac App Store). You can then copy it to your
applications folder, deleting the version that you got from the Mac App Store.
