How to prepare your Mac for R installation

The latest release R 3.6.3 runs smoothly on OS X 10.11 (El Capitan) and higher. Apple also notarizes this version, so it's fully compatible with Catalina.

Before installation, make sure you have at least 500 MB of free storage space on your Mac. To check it, go to the Apple menu in the top-left corner and choose About This Mac. Then, head over to the Storage tab.

If your space is a bit cluttered with files and data, you should consider clearing your hard drive before installing R.

Installing R on your Mac step-by-step

The easiest way is to install R through the Comprehensive R Archive Network (CRAN). Note that CRAN doesn’t have Mac OS X systems and can’t check these binaries for viruses. So they recommend using standard security precautions.
