Open Xcode’s Preferences, navigate to Components Toolchains, and select the installed Swift toolchain. Xcode uses the selected toolchain for building Swift code, debugging, and even code completion and syntax coloring. You’ll see a new toolchain indicator in Xcode’s toolbar when Xcode is using a Swift toolchain. Unfortunately Xcode is only for Macs but if you’re using a PC, there are alternative ways to run Xcode on Windows. Check out my guide for options! Xcode Alternatives.

This directory contains binaries for a base distribution and packages to run on Mac OS X (release 10.6 and above). Mac OS 8.6 to 9.2 (and Mac OS X 10.1) are no longer supported but you can find the last supported release of R for these systems (which is R 1.7.1) here. Releases for old Mac OS X systems (through Mac OS X 10.5) and PowerPC Macs can be found in the old directory.

Note: CRAN does not have Mac OS X systems and cannot check these binaries for viruses.Although we take precautions when assembling binaries, please use the normal precautions with downloaded executables.

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 (https://cran-archive.r-project.org) accordingly.

R 4.0.4 'Lost Library Book' released on 2021/02/15

Please check the SHA1 checksum of the downloaded image to ensure that it has not been tampered with or corrupted during the mirroring process. For example type
openssl sha1 R-4.0.4.pkg
in the Terminal application to print the SHA1 checksum for the R-4.0.4.pkg image. On Mac OS X 10.7 and later you can also validate the signature using
pkgutil --check-signature R-4.0.4.pkg

Latest release:

R-4.0.4.pkg (notarized and signed) SHA1-hash: 0b2b3bc846f6ebc72a8bc0b53e6e85d600d95deb (ca. 85MB)	R 4.0.4 binary for macOS 10.13 (High Sierra) and higher, signed and notarized package. Contains R 4.0.4 framework, R.app GUI 1.74 in 64-bit for Intel Macs, Tcl/Tk 8.6.6 X11 libraries and Texinfo 6.7.

Note: the use of X11 (including tcltk) requires XQuartz to be installed since it is no longer part of OS X. Always re-install XQuartz when upgrading your macOS to a new major version. Download el capitan iso. Also please do not install beta versions of XQuartz (even if offered). This release supports Intel Macs, but it is also known to work using Rosetta2 on M1-based Macs. Native Apple silicon binary is expected for R 4.1.0 if support for Fortran sabilizes, for experimental builds and updates see mac.R-project.org. Download itunes for macbook air catalina. Important: this release uses Xcode 12.4 and GNU Fortran 8.2. If you wish to compile R packages from sources, you will need to download GNU Fortran 8.2 - see the tools directory.
