How To Fix League of Legends Crashing or Not Opening in Mac?

Check out the various methods that have worked on many Mac machines and should work on yours too, fixing LoL in the process.

Method #1: Verify internet connection

League of Legends is an online game which means it requires a constant internet connection to keep it running. You need a stable internet connection with good strength or else you will face issues in the game or while launching it.

Go to fast.com and check the internet speed at the moment. The router or modem must be in a line of sight for better reception. Thus, you need to draw closer to the router for good strength. You can still use an amplifier to amplify WiFi signals for large distances but make sure the end goal is a stable internet connection with higher network reception.

Method #2: Check for outages

Since League of Legends is an online game, there are basically millions of users playing at any given time. If you aren’t familiar with how these online services are fed to the players, the game developers use servers spread across the globe to allow the gameplay. Riot Games, the developer for League of Legends, handles servers and if there’s a planned or sudden outage, you may lose the ability to play the game.

Of course, there isn’t just a single type of outage because some people may find it difficult to launch the game client, some would complain about login issues, and so on. Riot Games fixes server issues pretty proactively. This means if the League of Legends crashing on your Mac is because of a server issue, it should be fixed within a few hours.

You can check out Riot Games’ League of Legends server status as well as DownDetector for better resolution on server outages.+

Method #3: Change DNS Settings

• If you are using suboptimal settings on DNS to connect to the internet, you might struggle to launch the game client but there’s an easy fix to the problem.
• First up, open System Preferences on your Mac.
• Proceed to Network and tap on the active connection and go to its “Advanced”.
• Proceed to the DNS tab and take a screenshot of the existing settings FYI.
• You need to change the first row to “8.8.8.8” and the second row should be “8.8.4.4”.
• Press the “OK” and “Apply to Finish” and that’s it.

Note that in case if the internet doesn’t work after changing the DNS settings, you will have to revert the DNS settings. Take the screenshot you captured in the initial step of this method.

Method #4: Run the game in Riot MacContainer

Assuming that the League of Legends game client is too stubborn and is crashing or not opening, you need to launch it on RiotMacContainer. Here’s how you can do it.
First up, go to Finder >> Select and then, right-click on League of Legends.
Proceed to “Show Package Contents >> macOS >> tap on Rio MacContainer and close the game.
Check if it works or not. If not, try the usual method of launching the game client once again or proceed with the next method.

Once you have got rid of all the files, give your Mac a quick reboot and then, reinstall League of Legends and that should be done.

• Next up, you need to select your account as an admin. If you aren’t an admin, you need to go to “Lock >> Log in using an administrator account >> tickmark “Allow user to administer this computer” and relax.
