I’ll keep digging into this problem, but for now I’ll just share a few links where you can find more information.įirst, this Apple support page has these notes: Your Mac might wake for these activities: That being said, if you always use your MacBook as a laptop and only want the MacBook to wake up when you open the lid, you can un-check this setting.
