Several users have complained that the Steam app won’t open on their Mac. There could be several reasons why Steam might not be starting. It appears that the app icon keeps bouncing but fails to launch. Thus users are unable to play Steam games. This article explains how you can fix this problem.

Steam not opening on Mac

Steam is a video game distribution service. A lot of Mac users use this app to play games.

1. Basic steps

Please try these first:

  • Quit the Steam app and try to reopen it. Since the app is not launching at all, you can close it from the Dock. Find the Steam app, right-click (or control-click) and select Quit. Alternatively, you can also use Activity Monitor to quit it.
  • If you are unable to quit Steam, try force-quitting it. Press the Option, Command, and Esc (Escape) keys together and then select Steam and Force Quit.
  • Ensure that your Mac has the latest version of macOS. You can check if there is an update by going to System Preferences > Software Update.
  • Restart your Mac in Safe Mode. Test Steam in Safe Mode and then leave Safe Mode and test again. See this article on how you can use Safe Mode.

2. Use Terminal to open and update

You can use the Terminal app to force the Steam app to update. Here is how:

  • Quit Steam.
  • Open Terminal on your Mac (Applications > Utilities).
  • Enter the following command and hit enter:
Steam Terminal

3. Check Accessibility

Some apps, like Steam, may need to access and control your Mac through accessibility features to run properly. Here is how you can check this:

  • On your Mac, go to System Preferences > Security & Privacy.
  • Click Accessibility.
  • Click the Lock icon to unlock this section to make changes. And enter your password.
  • Select the Steam app’s checkbox.
