Setting aside the documented problems of running R natively on Apple's M1

That's rather dated: see the more recent reports on this list.
/index.html) and similarly the current lack of native versions of many
eco-system components (e.g. the discussion
here:https://github.com/neurolabusc/AppleSiliconForNeuroimaging ), will
code using parallel::mclapply() run as expected (i.e. on Intel hardware)
under emulation (Rosetta 2)? Has anyone tested this?
Yes: I have no idea why you would think otherwise. All mclapply uses is
forking, and the OS on an M1 Mac is the same as that on a (Big Sur)
Intel Mac (in many cases literally the same, with the same bi-arch
executables).
