4.      Deactivate your antivirus software

There is the possibility that the issue is being caused by a conflict between Steam and your antivirus software. Your antivirus software may be incorrectly identifying certain safe (and essential) Steam files as dangerous.

To check if this is the case, you can launch Steam after first turning off your antivirus software.

5.      Check for malware

As you probably already know, viruses and other forms of malicious software are major problems for computers. If you don’t know how to keep your computer free of viruses and other malware, then one may have already infiltrated it.

If malware attacks your computer, it can remove essential system files, causing Steam and other programs to crash abruptly.

You should install a trusted antivirus app such as Antivirus One and use it to scan your computer for malware. If any malware is detected, it will be removed automatically.

6.      Set the correct date and time

Incorrect Mac date and time settings can prevent Steam from launching. You can change your computer’s date and time settings in System Preferences.

If you are having problems changing these settings on your Mac, you may need to reset the NVRAM.

7.     Clear Steam cache

Because some Steam issues may not be related to the app itself but rather to its cache files (which are stored in your Mac’s Library folder) even reinstalling Steam may not solve the problem.

To delete Steam’s cache from your Mac:

  1. Open Finder and navigate to Library > Application Support. Delete the Steam folder.
  2. Select Go to Folder.
  3. Use Go to Folder to visit ~/Library/Caches~/Library/Preferences, and ~/Library/Logs and delete any Steam files from all of them.
