Caffeine is a free app that keeps the Mac awake.

The problem

Whenever the display goes to sleep on my MacBook, the drive shuts down and stops the back-up. This 2011 MacBook likes to meet energy guidelines and sleeps a lot, even with settings tweaked to the max in System prefs.

Also, a Mac laptop may want to sleep when it's not plugged in, but you don't want it to do this while it is showing a presentation.

The solution

I have used the free app Caffeine for years and it works great.

– Keith Hamilton

Once it is installed, click once in the menu bar to tell the computer not to sleep or show the screen saver.
