Mac R Uninstall: Force-Remove Stubborn Packages in 3 Steps

To uninstall R on Mac, you’ll need more than just dragging apps to the trash—some stubborn packages hide deep in your system. ⚡ I’ve wrestled with these remnants for years, especially after switching between RStudio versions, and here’s the method that finally cleans everything up without breaking dependencies.

Start by backing up any critical projects or scripts from ~/Documents/R/—this isn’t just about deleting files, but ensuring you don’t lose work tied to R’s libraries.

Then, we’ll tackle the three key areas: the main R.app and RStudio.app, the hidden framework files in /Library/Frameworks/, and the Homebrew-installed version if you used it. Each step targets a different layer of R’s macOS footprint.

You’ll end up with a completely clean slate—no lingering R processes, no half-removed frameworks, and a terminal that confirms which R returns nothing. The process takes about 15 minutes if you follow along carefully, and I’ll walk you through every command and file path so you don’t miss anything.

For the stubborn cases, we’ll cover how to handle permission errors, leftover config files, and even the rare instance where R’s uninstaller leaves behind ghost processes. Trust me—this method has saved me from more corrupted macOS installs than I’d like to admit.

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

Here's the foolproof method I use when R refuses to uninstall cleanly.

First, locate the R application in your Applications folder. Right-click and select Show Package Contents. Navigate to Contents/Resources where you'll find the uninstall script—this is R's built-in removal tool.

Open Terminal (press Command + Space, type "Terminal," and hit Enter). Drag the uninstall script into the Terminal window—it'll auto-fill the path. Press Enter to execute. The uninstaller will prompt you to confirm; type "yes" and press Enter again. Wait for the process to complete—this typically takes 30-60 seconds.

If you get a "command not found" error, the script isn't executable. Right-click it in Finder, select Get Info, and check "Is executable" under the General tab. Then try running it again.

R often leaves behind hidden files even after uninstalling. Open Terminal and run these commands one by one to clean up:

sudo rm -rf /Library/Frameworks/R.framework (this removes the core framework)
sudo rm -rf ~/Library/R (deletes user-specific R files)
sudo rm -rf /Library/PreferencePanes/R.pane (removes any preference panes)

You'll need to enter your admin password for each command. After running these, verify the files are gone by checking those locations in Finder (press Command + Shift + G and paste the paths).

If you see "No such file or directory", that's fine—it just means those files were already removed. The key is to run all commands to ensure a thorough cleanup.

R might still be referenced in your shell configuration files, causing it to reload when you open Terminal. Open Terminal and run:

nano ~/.bashprofile (or use ~/.zshrc if you're using Zsh, which is default on newer Macs).

Look for any lines containing "R" or "RHOME"—they might look like this:

export PATH="/Library/Frameworks/R.framework/Resources/bin:$PATH"

Delete those lines, save the file by pressing Control + O, then Enter, and exit with Control + X. Finally, reload your shell by running source ~/.bash_profile (or source ~/.zshrc for Zsh).

To verify R is fully removed, open a new Terminal window and type R --version. If you see "command not found", you've successfully uninstalled R. If not, repeat Step 2 and check for any remaining references.

Tips & tricks for completely removing R from your Mac

Here's what I've learned from years of dealing with stubborn software removals—these tricks will help you avoid common pitfalls and ensure R is truly gone.

Step 1: Make the Uninstall Script Executable First: Before running the uninstall script in Step 1, I always check its executable status first. Right-click the script in Finder, select "Get Info," and verify "Is executable" is checked. This prevents the "command not found" error that trips up so many people. Trust me on this—skipping this step wastes time and leaves remnants behind.

Step 2: Verify File Deletion After Manual Removal: After running the three commands in Step 2, don't just trust Terminal—actually verify the files are gone. Open Finder and navigate to each path (Command+Shift+G) to confirm deletion. I've seen cases where files appear removed in Terminal but persist in Finder, especially with system-level files like /Library/Frameworks/R.framework. This double-check ensures complete removal.

Step 3: Check Both Shell Configurations: In Step 3, you must check BOTH ~/.bashprofile AND ~/.zshrc if you're using Zsh (default on newer macOS versions). I've seen users miss this and still have R references in their environment variables. Open each file with "nano" and search for "R" or "RHOME" using Command+W—this catches all possible references that might resurrect R when you reopen Terminal.

Alternative Verification Method: If you're still unsure whether R is completely removed after following all steps, try installing a fresh copy of R. If it works without conflicts, you've successfully removed all remnants. This is my ultimate test—if a clean install works, you know the previous version is truly gone. Between us, this has saved me from headaches with leftover configuration files.
