> It seems that M4 chips can’t virtualise any version of macOS before 13.4 Ventura

13.4 was released on May 18, 2023. That's actually not very far into the past.

Anyway, what would be the most common use cases for this? And how common are those?

I once used an old Mac OS X in order to extract a Cisco AnyConnect certificate from Keychain that wasn't possible to extract in any other way.

I've first tried recompiling the Keychain app, but it had too many dependencies that were not trivial to build, so, using an older Mac, in that case, was the easiest way to get the private key from my own keychain.
