According to this post on the Carbon Copy Cloner web site, it is no longer possible to boot your Mac to an external bootable clone if the internal storage is not working. This at least partially defeats the purpose of making a bootable clone.
I want to know if it almost fully defeats the purpose. Can I still boot a different Mac (which still has working internal storage) to my bootable clone?
In other words, let's say we have 2 Macs, named Asterix and Obelix. If I clone Asterix's drive, and then Asterix's internal storage fails, can I plug the clone of Asterix into Obelix and boot it up there?
This other question has an answer that would seem to suggest "yes", but it is many years older than the blog post mentioning Apple having gutted this ability, and therefore doesn't give any indication whether that ability was preserved into the present or not.
