How To Uninstall League Of Legends On Mac Completely And Free Up Disk Space

Complete removal of League of Legends on macOS requires terminating the active Riot Client processes, deleting the core application binaries, and manually purging deep-seated user library files. Failing to delete these hidden support directories leaves up to 15 gigabytes of orphaned patch data and logs on your solid-state drive. Following this systematic, manual approach ensures a pristine removal of all game assets and reclaims critical system storage in under ten minutes.

Pre-Uninstall System Audits and Requirements

Before initiating the uninstallation process, it is important to understand how macOS handles application storage. Unlike modern operating systems that utilize centralized packaging, Riot Games distributes its assets across multiple directory trees on your Mac. Simply dragging the game icon from your Applications folder to the Trash leaves behind a massive trail of temporary game configurations, user settings, cached match histories, and system logs.

To execute a complete and safe manual uninstallation, you will need to prepare your environment. The system must be logged in under an administrator profile to modify protected folders, and you should ensure that all peripheral applications that interface with League of Legends are closed.

Pre-Uninstallation Checklist and Resource Allocations

To ensure a smooth file removal process, review the following checklist and technical prerequisites:

• Administrative Access: Ensure you have the administrator password or Touch ID authorized for your macOS user account to delete restricted system-level directories.
• Target Storage Reclamation: Plan to recover between 10 GB and 22 GB of storage space, depending on how many historical patch cycles your client has undergone.
• Time Commitment: The entire process takes approximately 5 to 10 minutes to complete manually.
• Required System Utilities: You will use built-in macOS tools including Finder, Activity Monitor, and the "Go to Folder" utility. No third-party software is required.

Step-by-Step Clean Uninstallation Protocol

This protocol guides you through terminating locked background processes, removing the executable binaries, identifying hidden system support files, and clearing out localized server logs.

Step 1: Terminating Active Riot and League Background Processes

The Riot Client and its auxiliary anti-cheat or launcher helpers frequently run in the background, even after you close the game window. If any of these processes are active, macOS will lock the files, preventing complete deletion and throwing errors.

1. Open Finder on your Mac, navigate to Applications, select the Utilities folder, and double-click to launch Activity Monitor. Alternatively, press Command + Space to open Spotlight, type Activity Monitor, and press Enter.
2. In the search bar at the top-right corner of the Activity Monitor window, type the word Riot to filter active processes.
3. Look for processes named Riot Client, RiotClientServices, or League of Legends.
4. Click on each relevant process to highlight it, then click the "X" button located in the top-left toolbar of the Activity Monitor window.
5. Select Force Quit from the dialog box that appears to ensure the background task terminates instantly.

Warning: Do not skip this step. Attempting to drag League of Legends files to the Trash while background processes are running can lead to corrupted directory paths and incomplete file removal.

Step 2: Removing Core Application Executables from Finder

Once all running processes are stopped, you can safely remove the primary applications from your main storage drive.

1. Open Finder and click on the Applications folder in the left sidebar.
2. Scroll down to locate the League of Legends application icon.
3. Right-click (or Control-click) on the League of Legends icon and select Move to Trash from the context menu. You can also drag the icon directly to the Trash can in your macOS Dock.
4. Locate the Riot Client application icon within your Applications folder.
5. Right-click the Riot Client icon and select Move to Trash.

Pro-Tip: If you installed the game through the Epic Games Launcher or another third-party portal, make sure to check if there are auxiliary game launchers sitting in your Applications directory that need to be trashed as well.

Step 3: Unveiling and Accessing Hidden User Library Directories

Riot Games hides the vast majority of its configuration files, patch data, and assets inside the hidden system User Library. Apple hides this folder by default to prevent users from accidentally deleting vital system configurations. You must bypass this restriction to clean out the remaining game remnants.

1. Ensure you are in the Finder application by clicking anywhere on your desktop.
2. Look at the top menu bar and click on the Go menu.
3. Select Go to Folder from the dropdown list. Alternatively, press the keyboard shortcut Command + Shift + G.
4. In the text field that appears, type the following exact path: ~/Library
5. Press Enter to open the hidden User Library directory.

Step 4: Deleting Game Configurations, Caches, and Riot Support Files

With the User Library open, you must navigate to specific folders to purge any assets associated with Riot Games or League of Legends. Use the search bar inside Finder if necessary, but ensure that the search scope is restricted to the Library folder rather than your entire Mac.

Navigate to the following directories and delete the specified targets:

• Application Support: Double-click the Application Support folder. Locate the folder named Riot Games. Right-click the Riot Games folder and select Move to Trash. If you see a separate League of Legends folder here, move it to the Trash as well.
• Caches: Return to the main Library folder and open the Caches folder. Look for folders named com.riotgames.LeagueofLegends and com.riotgames.RiotClient. Drag these folders to the Trash.
• Saved Application State: Navigate back to the Library folder, open Saved Application State, and find the folder named com.riotgames.LeagueofLegends.savedState. Move this entire folder to the Trash.
• Preferences: Open the Preferences folder within the Library directory. Find files named com.riotgames.LeagueofLegends.plist and com.riotgames.RiotClient.plist. Drag these files to the Trash.

Next, you need to check the shared user directory, which is a common storage point for Riot Client logs and cross-user data:

1. Open the Go to Folder utility again (Command + Shift + G).
2. Type the path: /Users/Shared
3. Press Enter.
4. Locate the folder named Riot Games in this shared space, right-click it, and select Move to Trash.

Step 5: Securely Emptying the Trash and Resetting the System Cache

To finalize the removal of these files and reclaim your hard drive space, you must empty the Trash and reboot your system.

1. Right-click on the Trash icon in your Dock.
2. Select Empty Trash from the context menu and confirm your decision in the system prompt.
3. Once the Trash is emptied, restart your Mac by clicking the Apple icon in the top-left corner of your screen and selecting Restart. This releases any cached memory allocations or system file locks that were associated with the game.

Resolving macOS Uninstallation Obstacles and Errors

During the uninstallation process, you may encounter system locks or file system permissions errors. Below are the most common failure scenarios and their technical remedies.

• Error: "The item cannot be moved to the Trash because it is open."
  
  
  • Root Cause: This occurs when a component of the game or the Riot Client is still active in the background, or a system thread has locked a resource file.
  • Actionable Fix: Open Terminal (found in Applications, then Utilities). Type the command "killall RiotClientServices" and press Enter. If that fails to clear the lock, type "killall LeagueofLegends" and press Enter. After running these termination commands, try dragging the files to the Trash again.
• Error: Permission Denied or Admin Password Prompt Loops
  
  
  • Root Cause: The Shared folder or Application Support files may have had their security permissions altered, making your user profile unable to edit them.
  • Actionable Fix: Right-click the problematic directory (such as /Users/Shared/Riot Games) and select Get Info. Scroll to the Sharing & Permissions tab at the bottom, unlock the panel with your administrator password, and change your user account permission status to Read & Write.
• Error: Disk space does not increase after emptying the Trash
  
  
  • Root Cause: macOS might be caching the deleted assets inside local Time Machine snapshots, or the operating system has not updated the volume indexing index.
  • Actionable Fix: Restart your computer in Safe Mode by holding the Power button down on Apple Silicon Macs (or holding Shift on Intel Macs) until the startup options appear. Safe Mode forces macOS to purge temporary system directories and update storage indexes.

Frequently Asked Questions

Does deleting the League of Legends app also delete my Riot account?

No, deleting the game files from your Mac only removes the local client, assets, and cache files. Your Riot Games account, virtual purchases, match history, and champion progress are safely stored on Riot's remote servers and will remain intact when you log in on another device or reinstall the game later.

Why is League of Legends taking up so much space on my Mac after uninstalling the main game?

This happens because the standard uninstallation only removes the core launcher binary located in the Applications folder. The actual game assets, textures, sounds, and patch updates are stored in the hidden Library directory, which requires manual removal to reclaim the associated gigabytes of storage space.

Can I use third-party cleaner apps to uninstall League of Legends?

Yes, third-party uninstallation software can sometimes automate this process, but they often miss hidden folders like the Shared directory or nested configuration files in the Library. Manual uninstallation is safer, completely free, and guarantees that no orphaned folders are overlooked.

How do I reinstall the game cleanly if I change my mind later?

To perform a clean reinstallation, complete the manual uninstallation steps outlined above to remove all residual files. Afterward, download a fresh installer directly from the official League of Legends website to ensure that corrupt files from previous builds do not interfere with your new installation.

Reclaiming Peak Performance for Your Mac

With all League of Legends system directories and game cache files purged from your hard drive, you will enjoy a significant boost in free disk space and overall macOS storage efficiency. If you are looking to replace the game with other software or want to further optimize your device, consider conducting routine checks on your system cache folders to keep your Mac running at peak speed.
