4. Check the Date and Time

This one might seem strange, but the “Steam quit unexpectedly error message” can be caused by incorrect or mismatched dates and times. If the date and time on your computer is incorrect or not set to the same as your game server’s, then this could be causing problems with Steam. Make sure that your PC’s date/time settings are correct, and try launching Steam again. If this doesn’t work, you can also manually sync the time from a reliable source like an online clock. You can do this by:
  1. Click on the Apple Logo and select System Preferences.
  1. Select General, then click on Date & Time.
  2. Make sure the Set Date and Time Automatically switch is toggled on. If the time is incorrect, then you can correct the time here.

5. Give Accessibility Permissions

Most of the time, when the Steam app doesn’t open for users, it’s because they haven’t allowed accessibility permissions. The first time you open Steam after downloading it, the app will ask for these permissions; make sure to click “allow” for all of them.
  1. Click on the Apple Logo, then select System Preferences.
  2. Open up the Privacy and Security tab, then click on Accessibility.
  1. From here, you can click the checkmark next to Steam to give it permission.

6. Reset SMC

The System Management Controller is responsible for the hardware functions of Intel-based Macs. A malfunctioning SMC can cause your Mac to overheat and crash Steam. The M1 Mac doesn’t have an SMC, as the functions it provides are handled by the M1 chip. If Steam crashes on your M1 Mac, restarting your computer after turning it off for 30 seconds will work similarly to resetting the SMC. The process of resetting an SMC differs from one Mac model to another, as well as between Intel-based Macs that have a T2 chip or movable battery. If you own an Intel-based Macbook with a non-removable battery, use the following instructions:
  1. Power down your Mac.
  2. Press and hold the left Shift + Control + Option keys along with the power button. Hold all four down for 10 seconds.
  3. Let go of all of the keys.
  4. When your computer powers back up, see if Steam is working properly.
