I upgraded to Catalina and everything worked fine except when trying to back to external using CCC. Got message that HD was not partitioned correctly.
I have given up on backing my computer. I have iPad which I use more. Bob
The latest update of SuperDuper cloning software (and probably CCC also) ¨C for Catalina ¨C needs the destination volume to be APFS. Mine was HFS+. SD notified me of that.
Since I was uncertain about converting 1 partition to APFS on a drive that was otherwise set up as HFS+ (and Time Machine still requires HFS+), I stopped and began to research the subject. I ended up erasing the destination partition, and let SD do its thing. It successfully converted the one partition to APSF, but the resultant clone had a problem (maybe my fault, maybe not), and I ended up erasing and re-cloning. At that point I had a bootable APFS Catalina clone in the layout (2 volumes) that Apple and SD both wanted.
