HOW TO UPDATE MAC OS 8.6 ARCHIVE

Any external libraries and tools are expected to live in /opt/R/arm64 to not conflict with Intel-based software and this build will not use /usr/local to avoid such conflicts.

If you wish to compile R packages from sources, you may need to download GNU Fortran for arm64 from. This release uses Xcode 12.4 and experimental GNU Fortran 11 arm64 fork. Always re-install XQuartz when upgrading your macOS to a new major version. Note: the use of X11 (including tcltk) requires XQuartz. Important: this version does NOT work on older Intel-based Macs. R 4.1.2 binary for macOS 11 ( Big Sur) and higher, Apple silicon arm64 build, signed and notarized package.Д¬ontains R 4.1.2 framework, R.app GUI 1.77 for Apple silicon Macs (M1 and higher), Tcl/Tk 8.6.11 X11 libraries and Texinfo 6.7.

If you wish to compile R packages from sources, you may need to download GNU Fortran 8.2 - see the tools directory. Important: this release uses Xcode 12.4 and GNU Fortran 8.2. For native Apple silicon arm64 binary see below. This release supports Intel Macs, but it is also known to work using Rosetta2 on M1-based Macs. Note: the use of X11 (including tcltk) requires XQuartz to be installed since it is no longer part of OS X. The latter two components are optional and can be ommitted when choosing 'custom install', they are only needed if you want to use the tcltk R package or build package documentation from sources. R 4.1.2 binary for macOS 10.13 ( High Sierra) and higher, Intel 64-bit build, signed and notarized package.Д¬ontains R 4.1.2 framework, R.app GUI 1.77 in 64-bit for Intel Macs, Tcl/Tk 8.6.6 X11 libraries and Texinfo 6.7.

On Mac OS X 10.7 and later you can also validate the signature using In the Terminal application to print the SHA1 checksum for the R-4.1.2.pkg image. Please check the SHA1 checksum of the downloaded image to ensure that it has not been tampered with or corrupted during the mirroring process.

Package binaries for R versions older than 3.2.0 are only available from the CRAN archive so users of such versions should adjust the CRAN mirror setting ( ) accordingly. Note: Although we take precautions when assembling binaries, please use the normal precautions with downloaded executables. Releases for old Mac OS X systems (through Mac OS X 10.5) and PowerPC Macs can be found in the old directory. This directory contains binaries for a base distribution and packages to run on macOS.
