One of the first things you should do is ensure that your macOS is up to date. Apple frequently releases updates that include bug fixes and improvements, which can help resolve compatibility issues with Steam. To update your macOS, go to the Apple menu, click on “System Preferences,” and then choose “Software Update.”

2. Verify Integrity of Game Files:
If Steam is not launching properly, it’s possible that there may be corrupted game files causing the issue. To check the integrity of your game files, open Steam and go to the “Library” tab. Right-click on the game that won’t launch, select “Properties,” and then choose the “Local Files” tab. Click on “Verify Integrity of Game Files,” and Steam will check for any corrupted files and repair them if necessary.

3. Disable Non-Essential Mac Applications:
Sometimes, certain applications or processes running in the background can interfere with Steam’s functionality. To troubleshoot this, try disabling any non-essential applications that might be running simultaneously with Steam. Close unnecessary applications from the Dock or use the “Force Quit” option by pressing Command + Option + Esc.

4. Check the Game’s System Requirements:
Ensure that your Mac meets the minimum system requirements for the game you’re trying to launch. If your Mac doesn’t meet these requirements, it may cause compatibility issues and prevent Steam from launching. You can find the system requirements on the game’s Steam store page or the developer’s website.

5. Close Steam Properly:
Sometimes, Steam may not close properly, which can prevent it from launching again. To fix this, open your Task Manager by pressing Command + Option + Esc, and look for Steam under the “Processes” tab. If you find it, right-click on it and select “End Task.” Now try opening Steam again, and it should launch without any issues.
