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.
