Review Comment:
I might explicitly link to https://cran.r-project.org/bin/macosx/ and say
install the arm64 version. And I (personally) would be a bit more direct:
you're running R built for Intel on a non-Intel mac, and arrow won't work in
that context; to fix, install the arm64 version of R from CRAN and then
reinstall R.
