Greg, Perhaps you're confused by the wording? It says "R compiled for High Sierra OR HIGHER". This is a minimum OS version. It doesn't mean you need to run High Sierra to use this binary. Best, Kasper On Thu, Jan 14, 2021 at 8:32 PM Gregory Coats via R-SIG-Mac < r-sig-mac@r-project.org> wrote:

The web site https://mac.r-project.org/ specifically shows that as of Thu 2021-01-14 00:56 1. R compiled for Big Sur for Macs with the Intel CISC x86_64 chip is NOT available. 2. R complied for "high-sierra” for Macs with the Intel CISC x86_64 chip IS available.

Hi Both versions seem to run fine indeed, but on my Mac mini M1, the arm version (homebrew R) is much slower than the intel version (CRAN R), which is quite disappointing. The speed ratio I get is about 4 times slower for the arm version compared to the intel version, both in single processor

I use the homebrew R for the Intel and then install.packages(), update.package() from scripts and  Rstudio’s Tools->. I don’t have an M1 (yet) but would be interested in seeing how that works on the M1. Probably this will pull the sources and hence I would be grateful to read about that.

It is my understanding that R is working via Rosetta 2 but I don’t have an M1 machine yet to test. See here: https://developer.r-project.org/Blog/public/2020/11/02/will-r-work-on-apple-silicon/index.html There is rapid movement on native ARM compatibility across all languages and software. Stay

I purchased a new 13 inch Apple MacBook Pro with the M1 System on a Chip. I understand that R is not yet available compiled for the M1 SoC hardware, and so I am using Apple’s Rosetta 2. However, this MacBook Pro requires Apple macOS Big Sur. From what I see at https://mac.r-project.org/ R has
