As Manfred mentioned, we have a version of QRecall that works with Sierra.
I'm pretty happy with the Sierra compatibility at this point. We've preformed several full-volume OS X restores and so on with no issues.
There were just a couple of other bugs and minor improvements that we'd like to get included in 2.0.4, and that's the only reason it hasn't been released yet. But we're ready to pull the trigger on 2.0.4 at anytime.
