For more details on compiling R, tools and libraries used for CRAN builds, please see https://mac.R-project.org/tools/
In short, you need at the very least Xcode and a Fortran compiler. R 4.5.0 and higher use universal GNU Fortran 14.2 compiler. You can download an installer package gfortran-14.2-universal.pkg (287MB) - for more details and other download options see R-macos GNU Fortran releases on GitHub.
For legacy tools used in old versions of R see the legacy tools page.
You may also want to read the R FAQ and R for Mac OS X FAQ. For discussion of Mac-related topics and reporting Mac-specific bugs, please use the R-SIG-Mac mailing list.
Information, tools and most recent daily builds of the R GUI, R-patched and R-devel can be found at http://mac.R-project.org/. Please visit that page especially during beta stages to help us test the Mac OS X binaries before final release! The page also contains links to experimental builds as such 64-bit R for OS X.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
