Will R Work on Apple Silicon? (Information on the status of the port to Apple's new M1 architecture.) Nightly builds for macOS R framework Build.For more information about alternative OpenMP options (as in older version) see the openmp page of this site. Please make sure you remove any modifications to build flags from your home ( ~/.R) since no custom compilers are used anymore. All dependent static libraries are available in the bin directory. Note that although M1 Macs can run the Intel build via Rosetta2 the native arm64 build is typically faster. Platform$pkgType) are "-sur-x86_64" for Intel and "-sur-arm64" for Apple silicon Macs. This is now true for both x86_64 and arm64 builds. R 4.3.0 CRAN builds are using Xcode 14.2/14.3, macOS 11.3 SDK and targetting macOS 11 (Big Sur) and GNU Fortran 12.2. Installer: R-devel-x86_64.pkg (91Mb, notarized) Installer: R-devel-arm64.pkg (92Mb, notarized) We are no longer building binaries for macOS versions before 11 (as they are no longer supported by Apple). big-sur-arm64 build supports arm64 Macs (M1+) from macOS 11 (Big Sur) and higher.
