Prevent Mac from Sleeping with pmset Command: A Simple Solution | MacOSXHints

Last Updated on April 19, 2024 by Freddy Reyes

We’ve run a number of hints about preventing a Mac from sleeping, such as this and this.

I came across another really simple way to do this, using the pmset command. Just run this command in terminal:

pmset noidle

Terminal will display the following text:

Preventing idle sleep (^C to exit)...

To allow the Mac to go back to sleep, according to its current Energy Saver settings, just press Control-C.
