MacBook Pro: How to Prevent Sleep When Using an External Monitor

If you’re using your MacBook Pro with an external monitor, you may have noticed that your computer goes to sleep after a certain amount of time. This can be annoying if you’re working on something and don’t want your computer to go to sleep. Luckily, there’s a way to prevent your MacBook Pro from sleeping when you’re using an external monitor.

The first thing you’ll need to do is open up System Preferences. You can do this by clicking on the Apple icon in the top left corner of your screen and then selecting “System Preferences.”

Once you’re in System Preferences, click on “Energy Saver.”

On the Energy Saver preferences pane, you’ll see two options: “Battery” and “Power Adapter.” Make sure that the “Power Adapter” option is selected.

Under the “Power Adapter” options, you’ll see a checkbox next to “Prevent computer from sleeping automatically when the display is off.” Make sure that this box is checked.

Now, your MacBook Pro should stay awake when you’re using it with an external monitor. Keep in mind that this will also keep your computer from going to sleep when you close the lid, so you’ll need to remember to put your computer to sleep manually when you’re done using it.
