FANTASTIC NEWS!!!! SuperDuper! V 3.5 (beta for now) functions as expected with Big Sur!

This is a truly wonderful development:

As dedicated user of SuperDuper!, I've been hoping that Dave Nanian would come through. Well, he has! The only remaining issue I am having with OS 11.4 is that the eDrive for Tech Tool Pro can be created, but then does not show up on the list of bootable devices. But I am getting close to abandoning Tech Tool Pro, as for the critical functions it performs, Disk Utility can do it.

Note that it functions with both Intel and M1-based Macs. although for M1 Macs, one must use OS 11.4, which is the latest version of Big Sur (V11.5 is in beta testing now).

In any event, definitely a happy day!

    Correction: meant to say Big Sur V11.3 with my testing, and issues with Tech Tool Pro. V 11.4 is currently in beta. As it is, this new version of SD will only work with Big Sur V11.4 (and of course with a number of versions of the Mac OS prior to Big Sur). Myself, this will spur me on to purchase M1 versions of the Mac Mini and Mac Book Air.

    Just looked at Shirt Pocket's site, and Dave provided an update:

    Note that the requirement of OS 11.4 is for M1-based Macs only.

    Good to see he is making definitive progress. I am waiting for OS 11.4 to be released, and assuming it is just about bug free, I will attempt to sell my 2017 MacBook Air and my 2018 MacMini, and then purchase M1 versions of both of them. Hopefully all that will work out well for me.
