So, it's been a while!

For the tl;dr crowd out there, SuperDuper! 2.7.1 backs up Mavericks just fine, so we've got you covered, day-and-date, with backups.

In addition, I'm happy to announce that we will, have an even better Mavericks-compatible release 2.7.2 available shortly.

For more patient readers, here's some hopefully interesting detail.

Despite few visible changes, we've done quite a bit behind the scenes to bring back the cool automatic volume mount/eject feature that stopped working in Mountain Lion because of some new "security features". (It should also eliminate that intermittent, weird, unclickable "Application isn't running" panels and the like that occasionally happened to a few users.)

But every OS release presents new challenges, and Mavericks is no exception.

As you may know, our scheduling feature runs a little application called "Copy Job" behind the scenes. Copy Job gets launched by the system, figures out what the scheduled copy should be, and then launches SuperDuper! to actually do the copying.

When Copy Job starts, one of the first thing it does is ask the OS whether SuperDuper! is already running. That way, it knows whether or not it should quit it at the end of a successful backup.

For some reason, in Mavericks, this check (and a second one that checks whether Growl is running) now generates a scary security warning that claims Copy Job is trying to strangle kittens or some such—and then doesn't give you an easy way to disable the warning (it's a multi-step, confusing process, as you'll see).

We've found a way around this prompt, but it requires that you delete and recreate your existing schedules once 2.7.2 is released. To be blunt, that sucks, I wish it wasn't necessary, and I'm truly sorry for the hassle.

On a slightly sad note, the new 2.7.2 version drops support for Tiger and Leopard (10.4 and 10.5). It's become too difficult to build and test new versions that are compatible with these years-old OS versions (hard to believe, I know, but Tiger came out in 2005, and Leopard in 2007).

2.7.1 will still be available, of course, and can still be used with those older OS versions.

The new 2.7.2 version is in the final stages of testing, and will be available for automatic upgrade shortly as a free update.

Thanks for reading, and thanks for using, trusting and recommending SuperDuper. We couldn't do this without you.
