Late 2015 iMac which Apple says can be upgraded to Big Sur.
I’m sure someone here will have a good answer for this.
I’m running 10.14.6, and am planning to skip Catalina and eventually move to Big Sur. I have two TM backups and two SuperDuper clones on external, wired HDs.
Is it feasible, advisable and practical to boot from one of the SuperDuper clones and upgrade it to Big Sur, just to see how it works and if I like it? (I realize SD hasn’t been updated to be able to make bootable clones in Big Sur, but I believe this is imminent from info posted on the Shirtpocket side/blogs.)
Thanks for any and all ideas.
