If it's not one thing, it's nothing, at least this time.
We'd developed the current Beta of SuperDuper using the most current Developer Beta versions, based on the feedback of various testers (and, of course, our own testing).
As I mentioned in my last blog post, we'd researched the problem we had copying El Capitan, and we came up with a way of getting the drive copied, although System Protection was disabled on the copy until the OS was reinstalled.
We thought it was critical to release that as soon as the Public Beta was announced, to ensure that the larger pool of public testers had access to it - we didn't want that audience to go without the ability to back up. And it's been working great.
Turns out...
Apple fixed the problem with copying the "com.apple.rootless" attribute in the Public Beta! So, with the release of our Beta 2 (download below), we've included the ability to copy with that EA preserved, and thus system protection is maintained on the copy as well. Plus, there's no need to erase when restoring.
This is all great news for users: basically, copying will work as it always has.
You can download the improved/de-improved Beta 2 here. Enjoy!
