How Do I Prevent My Mac Display From Turning Off When Pushing The Power Button?


Is there a way to stop my MacBook Pro display from sleeping when I accidentally hit the power key on the keyboard?

Yes, launch the Terminal app (it's inside Applications > Utilities) and then paste in the following command:

defaults write PowerButtonSleepsSystem -bool no

Hit return and the change will go into effect. If you ever want to undo this change, go back into Terminal and paste the text below, followed by hit return:

defaults write PowerButtonSleepsSystem -bool yes
