How to download R on Mac

R is a programming language and open-source, cross-platform software environment for graphics and computing. Developed in 1995, it has become one of the main languages used for data science and machine learning today. R is popular among not only academics but also global tech giants like Google and Microsoft as well.

In this article, you’ll find the easiest way to download R for Mac. We’ll as well dig into everything you need to know to install RStudio, which is an integrated development environment (IDE). It makes using R much easier because of its user-friendly interface and a bunch of customization options. Let’s get started!

How to prepare your Mac for R installation

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 > More Info > Storage Settings. Alternatively, go to System Settings > General > Storage. 

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

All the junk files you have on your computer not only occupy gigabytes of space but also overload the CPU a lot. Heavy junk clusters can hide deeply in your system, so getting a little help with cleanup is the way to go.

CleanMyMac X by MacPaw is one of our favorite tools, as it helps you manage your storage, maintain your Mac’s performance, and protect it from malware all at once. Here’s how to use it:

1. Download and install CleanMyMac X — get the app for free here.
2. Open it and run the Smart Scan by clicking Scan.
3. Once you see results, click Run to clear the junk.

You can also check out the Large & Old Files tab to remove the heaviest files that have been piling up on your Mac for way too long. Now, your Mac is ready for 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.

Even though severe malware attacks are not so frequent on macOS, regular checkups are essential. Luckily, CleanMyMac X includes a Malware Removal tool to protect your Mac from hazards.

To check your Mac for malicious programs, including viruses and worms:

1. Open CleanMyMac X.
2. Navigate to Malware Removal.
3. Click Scan to let the app analyze your system.
4. If it finds something malicious, click Remove to get rid of it.

Now that your Mac is protected, it’s time to visit the CRAN download page and grab your copy of R. It’s totally free. Here are some steps to follow:

1. Open your browser and go to cran.r-project.org.
2. Click Download R for macOS.
   
3. Click on the first link under the Latest Release. Select the version that would work with your Mac based on the chip it comes with — Apple silicon or Intel. 

   

   
   
4. Double-click the .PKG file from the Downloads folder to open the package installer.

   

   
   
5. Follow the on-screen instructions to proceed with the installation. Accept the default settings.
6. Once done, move the installer to the Trash.
   
7. Finally, click Close. Congratulations! Now you have R on your Mac.
