Hi,

You are mis-reading that page.

With respect to Apple Silicon (M1/arm64), the *development* version of R 4.1.0, which is not yet released, and is a nightly, unstable, build, does not compile:



That version is not intended for production use.


At the top of the page, you will find the following:




The current, stable, release version of R, which is 4.0.3, works just fine on Intel based Macs running Bug Sur:

  https://cran.r-project.org/bin/macosx/ <https://cran.r-project.org/bin/macosx/>

I am running that version on my Intel Mac, running Big Sur 11.1.

If you follow Prof. Ripley's updates on the list, regarding Apple Silicon specifically, you will see additional information, including CRAN package testing:
