Dave Nanian’s SuperDuper is a superb tool and as an independent developer his responsiveness to questions and his resourcefulness under Mac OS X and macOS is inspiring.

Apple is making a lot of unpredictable moves in the name of security and a lot of uncertainty now surrounds the future of bootable backups as protection against catastrophic data loss and/or transformation.

It’s good to see SuperDuper have a partial path forward. I’m crossing fingers Apple will be able to reshape its security paradigm while enabling third-party backup software to create bootable backups for Apple Silicon machines.
