Factorio Forums

On Mac, when the game is running, screen saver, display off, and sleep are inhibited. Overall this is a good thing. When the game is paused (e.g pressing escape for the load/save menu in single player), though, it still happens even though it's not necessary at all. This means if I pause and go to bed, the computer and monitors stay on all night. Have to manually save and quit the game if I want the computer to go to sleep. Factorio could remove the wake lock (IOPMAssertion or similar) when the game isn't actively running.

Sleeping while Factorio is running is not supported. Sometimes OS doesn't recover our textures after waking up from sleep and the game needs to be restarted anyway.
