I wouldn't be completely surprised if there is a box running a build of Mac OS for RISC V somewhere in Cupertino!

Seriously though, I suspect that the ISA isn't that important for Apple but on the other hand I think they're probably quite happy with the direction of the Arm ISA (probably had a big say in parts of it) and it would take quite a lot to push them away.

I think that the odds on the Nvidia takeover are quite small by now so don't think a move likely at all.

Apple's aggressive removal of legacy stuff means the apps they do have are mostly kept up to date, so they have that going for them. On the desktop the major Mac OS only apps are now a) owned by Apple and b) rewritten from scratch so are easy to port to ARM, and therefore most likely, anything else.

Will RISC V do what ARM did to x86? Start at the low end, be more open, and slowly take over.

I think that's unlikely - Arm gradually replaced a number of in-house ISA's and designs because the economics didn't support each firm doing their own thing. I'd be surprised if in many cases - except for eg Western Digital - the economics of going RISC-V make sense.
