What's the point of using SD if it can't produce a bootable clone and won't be there for you in case of an emergency? (I thought that issue had been resolved.)
Exactly! But, as I mentioned in my post above, the notion that one cannot boot their Mac from a "El Capitan" SD backup/clone is definitely false. The version of SuperDuper! that came out right before OS 10.11 was released has always worked fine.
