You are being quite rude, repeating the same incorrect information.

Prof Ripley's notes were not about your system, they were about the M1 Macs.

For your system,

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

contains a build of R 4.0.3 that is "for macOS 10.13 (High Sierra) and 
higher".  That's what Jean Thiolouse was referring to.

It's possible that the package on CRAN doesn't work on your system, but 
it doesn't sound as if you've tried it.
