Keep MacBook from Sleeping with Lid Down
The MacOS app Amphetamine is pretty slick. As promised, it keeps my MacBook Air awake even if the lid is closed and there is no external display attached. So now I can run it as a part-time file server (via SFTP and Secure ShellFish for iOS). At least, that’s the plan. Since it is running on a laptop, I really appreciate the audio alert it’ll give if I unplug the MBA while Amphetamine is keeping it awake.
