How to Uninstall R on Mac: No-Trace Removal in 3 Simple Commands

Uninstalling R from your Mac shouldn’t feel like hunting for digital ghosts—especially when three commands can wipe it clean. ⚡ I’ve helped colleagues erase stubborn R installations without leaving traces, and the process is simpler than most tutorials admit.

The key is knowing where R hides its files and how to pry them loose without breaking other tools.

First, check if R was installed via Homebrew, the macOS installer, or manually in /Library/Frameworks/. Open Terminal and run which R—if it returns a path, you’ll need to target that location.

Skip this step, and you might leave behind libraries that clutter future installs. I’ve seen RStudio projects fail because of leftover packages, so we’ll cover how to scrub those too.

You’ll use brew uninstall r for Homebrew installs, or manually delete /Library/Frameworks/R.framework/ if you went the GUI route. For stubborn remnants, a sudo rm -rf command (with the exact path) does the job—just double-check you’re not deleting system files.

The whole process takes under five minutes if you follow the right order, and I’ll show you how to verify it’s gone.

After removal, test by typing R in Terminal—nothing should appear. If RStudio still detects R, clear its cache (usually in ~/Library/RStudio/). This method works for R 4.0+, and I’ve used it on every macOS version since High Sierra without issues. Let’s get started—no traces left behind.

What you need

Step-by-Step instructions for removing R from your Mac completely

Here's the foolproof method I use to wipe R clean—no leftover files or hidden caches.

Open Finder and navigate to Applications. Locate the R application (usually labeled just "R" or "R.app") and drag it to the Trash. Empty the Trash immediately to permanently delete the application.

Next, open Terminal (press Command + Space, type "Terminal," and hit Enter). Run this command to remove the R framework files: sudo rm -rf /Library/Frameworks/R.framework. You'll need to enter your admin password when prompted.

This removes the core R installation, but some preference files may remain. We'll handle those next.

In Terminal, run these three commands one by one to remove hidden R configuration files:

rm -rf ~/Library/R/ — This deletes user-specific R settings and packages.

rm -rf ~/Library/Preferences/org.R-project.R.plist — Removes R's preference file to ensure a clean slate.

rm -rf ~/Library/Application Support/R/ — Clears any remaining support files that might conflict with future installations.

I always verify these folders are empty afterward by running ls ~/Library/R/ and ls ~/Library/Application\ Support/R/. If any files remain, delete them manually.

Run this command to delete all installed R packages and cache files:

rm -rf ~/Library/R/arm64/ (for Apple Silicon) or rm -rf ~/Library/R/x86_64/ (for Intel Macs). This removes all package libraries that might linger.

For a thorough cleanup, also run:

rm -rf ~/Library/Caches/org.R-project.R/ — This removes cached package data that could cause installation conflicts later.

Finally, restart your Mac to ensure all processes have fully terminated. This step prevents any lingering R processes from interfering with your next installation.

Open Terminal again and run which R. If R is fully uninstalled, you'll see nothing returned. If you still see a path, repeat Step 1 and Step 2.

To double-check, try launching R from Spotlight (Command + Space, type "R"). If it doesn't appear, you've successfully removed it. If you see any remnants, delete them manually from ~/Library/.

Real talk: Some users report leftover files in /usr/local/bin/. Run ls /usr/local/bin/ | grep R to check. If you find anything (like Rscript), delete it with sudo rm /usr/local/bin/Rscript.

Tips & tricks for perfect R removal on Mac

A few simple tricks that'll make sure R disappears completely from your system—no hidden files left behind.

Backup First: Before running any commands, I always create a backup of my entire system using Time Machine. This isn't just paranoia—some users accidentally delete important files when cleaning up R's remnants. You can restore from backup if anything goes wrong, and it only takes a few minutes.

Command Order Matters: In Step 2, follow the exact sequence of commands I've listed. Starting with ~/Library/R/ first prevents permission errors when trying to delete the other folders. If you get "Operation not permitted" errors, run sudo chmod -R 777 ~/Library/R/ before deleting, but only do this if you're comfortable with changing permissions.

Verify Before Deleting: When checking folders with ls ~/Library/R/ in Step 2, don't just glance—actually confirm they're empty. I've seen users miss hidden files because they didn't verify properly. If you see anything suspicious, delete it manually with rm -rf after the folder name.

Restart is Non-Negotiable: That final restart in Step 3 isn't optional. Some R processes run in the background even after you've deleted everything. Skipping this step might leave remnants that cause issues when you try to reinstall R later. Trust me on this—it's worth the extra minute.
