If you suffer from frequent crashes/lagging/hanging in game this may be because your Mac is running out of RAM whilst you’re playing. You need to free some of it up and you can easily do this whilst you’re playing. You can buy apps from the App Store to do this but why bother when you can do it through Terminal for free?

If you are experiencing the following error:

“Cannot start the process when the game is running. Please quit the game and try again”
