# Myst III: Exile – The game fails to save/load/run in MacOS Catalina. Help?

**Issue:** After buying and installing Myst III on my Mac running OS Catalina, I found I could not run, save, or load games!

**Solutions:** Grant “Full Disk Access” to Myst III in the Accessibility and Privacy Settings.

If that fails to allow Myst III to run, save, or load games, try the following:

Start Myst III using “sudo” from the terminal. Running the game using “sudo open” should resolve the issue.
