FIX: Steam Quit Unexpectedly on Mac In 2022

While trying to launch Steam, some users found Steam to quit unexpectedly on Macs.

This can happen due to corrupted Steam files, insufficient permission, antivirus or system bugs.

If you are also facing this issue on your Mac, then read this article and learn the solutions for it.

What To Do When Steam Quit Unexpectedly On Mac?

Follow this step-by-step guide when Steam is quitting unexpectedly on Mac.

Also know what to do when DLC is not downloading on Steam.

1) Force Quit & Restart Steam

When Steam OSX quits unexpectedly, force quit Steam and restart it.

To do that, follow the steps given below:

  • Click on the Apple icon and select the Force Quit option.
  • When Force quit application opens, select Steam & click on the Force Quit option.


  • Wait for a couple of minutes. Restart Steam and check if the problem is gone now. If Steam again quits then go to the next step.

2) Disable Antivirus 

Sometimes antiviruses may detect Steam as a threat and prevent it from functioning properly.

So, disable your antivirus temporarily and see if that solves the problem.

3) Update Mac

If you are using an outdated version of Mac, then this can be the reason why Steam is quitting unexpectedly on Mac.


After updating Mac if you still see Steam is unexpectedly quitting in Mac then g to the next step.

4) Turn Off the Bluetooth 

If you have connected any Bluetooth devices to your MacBook, then it can conflict with Steam and cause issues.

So, turn off Bluetooth and launch Steam. Make sure that Steam can access your Mac, here is how you can check that:

  • Click on the Apple menu and select System Preferences.


  • Choose Privacy & Security and then click on Privacy.


  • Click on the padlock and check the box for Steam. This will provide permission to Steam for accessing Mac.

5) Reset The System Management Controller 

SMC or System Management Controller manages all the hardware functions for the Intel-based MacBook.

If SMC becomes faulty, then also Steam may crash on Mac. So, reset SMC to fix the problem.

The steps to reset SMC may differ from model to model. Here I am showing the steps on a Notebook Mac having a non-removable battery:

  • Shut down the MacBook.
  • Press and hold the Shift + Option + Control buttons for 10-15 seconds. Release the keys and then press the power button to turn on the Mac.

6) Reinstall Steam On Mac

If Steam is still closing unexpectedly after performing the above steps, try reinstalling Steam. To do so, follow the steps given below:

  • Click on Finder and then go to Applications. Select Steam and then right-click on it. Click on the Move to Bin option.


  • Select Go and click on Go to Folder option.

Navigate to:

 ~/Library/Application Support and press the Return key.


  • Right-click on the Steam folder and select Move to Bin.
  • Delete all the folders except the SteamApps folder. This will keep all your downloaded games and save game data.
  • Restart Mac and download Steam.
  • Open the downloaded file and then drag Steam to the applications folder.
  • Run the folder to install Steam. Launch Steam again and this time you should be able to run it without further difficulties.
