League of Legends is one of the most popular MOBAs to arrive on Mac, with thousands of players battling each other across the globe every day. However, Mac players do suffer from one disadvantage when compared to their Windows or Linux friends — smooth performance. Macs have fewer game-oriented video cards in the beginner to intermediate models, which could mean lower frames per second (FPS) rate for many players.

You can be sure that in the middle of a gank, solo fight, or rax, every frame counts. Smooth performance can be the difference between landing a stun, using an item, or helping your teammates in a split-second. When the stakes are high, don’t let slow performance and lag drag you down.

Why Is League Of Legends Slow On My Mac?

League of Legends is one of the easier MOBAs to run thanks to a lightweight graphics engine and a smart team of engineers at Riot games. However, the load on your Mac can become fairly high as the match progresses. Champions level up and have more skills. They earn more money and have more items. In a late-game group fight, your Mac is processing so many actions at once that it can bog down the framerate. On top of this, your internet connection has to send all of this data to the server and back so that everyone is on the same page.

There are five different paths, but players can sometimes feel pressured by the presence of runes. To truly use what a League champion has to offer, runes need to fit the role, the character being played, and the player’s playstyle.

Between the infamous League of Legends slow motion bug and even some issues with League of Legends slow updates, optimizing your Mac is more important than ever to winning your next game.

1. Disable shadows

One of the most demanding graphical components in the League of Legends engine is the shadow processing engine. It renders the shadow of every champion, tree, and blade of grass on the map, which then have to respond to the conditions around them, such as spells and changing light. To speed up League of Legends, the game stores most of the shadow assets and states in your video RAM (VRAM). The more VRAM you have, up to approximately 2 GB, the smoother your FPS. But disabling shadows completely in the Video options can increase your FPS and also give you extra visibility on the map (with fewer distracting shadows). To access the Video options, simply press Esc and then select Video. While you’re in there, try setting the overall graphics quality to Very Low.

2. Close all other apps

League of Legends on Mac plays better when there are no other apps using valuable RAM and resources in the background. Common culprits include Dropbox, Messenger, WhatsApp, and Google Drive. By closing these apps before you play, you’re making more RAM and processing power available to speed up League of Legends. To identify and close any resource-hogging apps, simply:

1. Launch Activity Monitor from Applications.
2. Switch tabs to Memory and make a note of the apps at the top of the list.
3. Switch tabs to CPU and see what’s taking up processing power.
4. Quit all the apps you don’t need by selecting them and choosing Force Quit icon in the top-left corner.

If closing these apps didn’t seem to make an impact on speeding up your League of Legends, try restarting your Mac first for a clean wipe of RAM usage.

3. Repair corrupt game files

League Of Legends For Mac

League of Legends, like other MOBAs, is updated very frequently for new champions, items, bug fixes, or balances. Over time, your game files can become corrupt due to an error in processing the new files upon each update. Occasionally, this can lead to FPS problems and slow performance. Thankfully, League of Legends has a built-in repair function that will fix any corrupted files:

1. Run League of Legends.
2. Click on the gear in the top right corner of the window.
3. Click Initiate Full Repair.
4. Wait for the repair function (it can take from 5 minutes to over 30 minutes depending on the corrupted files).

If in doubt, you can always try reinstalling League of Legends entirely so that fresh new files are pulled from the install.

4. Remove resource-heavy and temp files

While there are some good tips for speeding up League of Legends FPS in the game settings, there are some optimizations that can only be done inside macOS. With use, your Mac becomes full with all kinds of files you don’t need that still consume your processor’s speed. But how do you find them?

A popular trick used by pro gamers is to fire up an automatic optimization tool like CleanMyMac X, which finds the files that slow you down so you can focus on landing that next stun.
