How to Keep Your Mac From Falling Asleep

One day, you’ll want to keep your Mac up with you. Give it some caffeine with the “caffeinate” command.

What’s “caffeinate” do?

Open up Terminal or iTerm 2 and check out the man pages:

man caffeinate

How would I use it?

Just type in:


and your Mac will stay awake until you press Control + C to stop the command.

If you’d like, a timer to automatically shut it off is available.

caffeinate -u -t 120

Remember the “120” above is in seconds. In the above example, it would stay up for two minutes.
