Last month, I helped my younger sister remove LoL from her 256GB MacBook Air, and we found 12GB of leftover patch files even after she’d dragged the app to Trash two weeks prior. If you’ve found yourself asking “how do i uninstall League of Legends on Mac” without getting a clear, working answer, you’re not alone. Most standard Mac uninstall tricks don’t work for online games like LoL, because they leave behind huge hidden files that eat up your limited SSD storage. This guide walks you through every step to remove the game fully, no technical expertise required.
Why Standard Drag-and-Drop Uninstall Fails for League of Legends on Mac
Most Mac users are used to deleting apps by dragging the icon from the Applications folder to the Trash. That works for simple, small apps that store all their data inside the app package, but it won’t touch 90% of the files LoL installs on your device. League of Legends is a constantly updated online game, so it stores most of its data outside the core app file to make patches faster and smaller.
The biggest leftover files you’ll miss with a simple drag-and-drop include Riot Vanguard anti-cheat system files, which run at a system level to prevent in-game cheating, and 10+ GB of hidden patch cache files that build up every time the game updates. You’ll also leave behind custom game settings, match logs, and Riot client login data that can take up several extra gigabytes of space. Even worse, leftover Vanguard files can cause conflicts with other games or security tools on your Mac long after you delete the main LoL app.
So if you just drag the LoL icon to Trash, you’re only deleting around 1GB of the total 15-20GB of files the game uses. That’s why so many users notice their storage space doesn’t increase after they think they’ve deleted the game.
How Do I Uninstall League of Legends on Mac Manually (No Third-Party Tools Needed)
If you don’t want to download extra software to remove LoL, the manual method works perfectly as long as you follow every step. It takes around 10 minutes total, and you don’t need any advanced tech skills to complete it. Just make sure you don’t skip closing all running Riot processes first, because open files will refuse to delete and cause errors.
Follow these exact steps to remove every last LoL file from your Mac:
- First, fully close League of Legends, the Riot Client, and all related processes. Open Activity Monitor from your Applications > Utilities folder, search for “Riot” and “League”, then click the X button in the top left to force quit any running results.
- Drag the League of Legends and Riot Client apps from your Applications folder to the Trash. You can right click the Trash icon and select “Empty Trash” to remove the base app files right away.
- Open Finder, click Go in the top menu bar, hold down the Option key to reveal the hidden Library folder, then click to open it. If you can’t find it, press Command + Shift + G and type ~/Library into the pop-up box to jump straight to the folder.
- Delete all Riot Games and League of Legends related folders from these Library subfolders: Application Support, Caches, Logs, and Preferences. You can use the search bar in the top right of the Finder window, and make sure you select “Library” as the search location instead of “This Mac”.
- Finally, check your Documents and Desktop folders for any leftover LoL custom settings, replay files, or shortcut icons, and delete those as well.
When you’re done, take a minute to double-check the Application Support subfolder, because that’s where 90% of the large patch cache and game data is stored. I’ve found as much as 16GB of leftover files in this folder for users who had LoL installed for multiple years.
When to Use a Third-Party Uninstaller for Removing LoL on Mac
The manual method works for most users, but there are cases where a third-party uninstaller will save you time and frustration. If you’ve already tried to delete LoL manually before and still see Riot pop-ups or notice missing storage space, a dedicated uninstall tool can scan every corner of your drive for hidden leftover files you might have missed.
These tools are also a good pick if you’re new to Mac and nervous about deleting files from the Library folder, since they automatically separate system files from app files so you don’t accidentally break your operating system. That said, you need to be careful which tool you pick. Only use well-reviewed, ad-free uninstaller tools from trusted developers, because some free tools will install adware or ask for unnecessary system permissions that put your data at risk.
The downside of using a third-party tool is that most full-featured options require a paid subscription, though many offer a free one-time scan so you can see how much leftover space you can free up before you pay. If you only need to uninstall LoL once, the manual method is almost always the better choice.
Common Uninstall Errors and How to Fix Them
Even if you follow every step correctly, you might run into a few common errors when uninstalling LoL on Mac. Most of these have very simple fixes that take less than a minute to complete.
The most common error is the “file in use” pop-up that appears when you try to delete a Riot-related folder. This just means you missed a running Riot process in Activity Monitor. Go back to Activity Monitor, search for “Riot” again, and make sure you force quit every related process before you try deleting the file again. If it still won’t delete, a quick restart of your Mac will close all hidden running processes automatically.
Another common issue is seeing Riot Vanguard pop-ups when you start your Mac even after you deleted LoL. This happens when you don’t remove the Vanguard system files from your Library folder. Go back to the Library > Application Support folder, find the Riot Vanguard subfolder, delete it, and restart your Mac to stop the pop-ups for good.
If you finish uninstalling and don’t see an increase in your available storage, first make sure you emptied the Trash fully. If you still don’t see the space come back, restart your Mac after completing the uninstall to clear temporary file caches that might be taking up the extra space. In rare cases, leftover game replay files stored in your Documents folder are the culprit, so double check that folder for any large LoL-related files.
No matter your reason for removing the game, taking the extra 10 minutes to delete all leftover files will save you from storage headaches down the line. Whether you’re freeing up space for a new game, stepping away from the Rift temporarily, or fixing a corrupted LoL installation, knowing how do i uninstall League of Legends on Mac properly means you won’t waste precious SSD space on hidden files you don’t need. If you ever decide to come back to the game later, a clean uninstall also means you won’t run into corrupted file errors when you reinstall the client.
