Amphetamine

I know, the name isn’t something you’d expect from an app, but Amphetamine is a great app for when you need your Mac to stay awake.
If you’ve ever needed to keep your Mac awake, and you’ve been forced to stay close and move the trackPad every once in a while, you might need this app.
Amphetamine has many options and tools to keep your Mac awake with a simple click. Not only that but it has more advanced features for people who need them. With Amphetamine, you can keep your Mac awake with different triggers, and even make it so your Mac won’t go to sleep mode while certain apps are running.
You can even keep your MacBook awake even when is closed. That’s really great for when you need to download a huge file, but you don’t want your MacBook to be open, or you need to be on the move.
