You may want to keep Mac from sleeping when you are downloading big files, performing Time Machine backup, rendering a video file, and in other similar situations. Doing this is easy. You can use the macOS System Preferences, use third-party apps, or use the Terminal. But what if you want to prevent MacBook from sleeping even when you close its lid?
Well, this is also quick and easy. There are two straightforward ways to keep the MacBook from sleeping with lid closed. First is to use an external display, and the second method requires a third-party app. Let us dig in and see both.

Keep MacBook from Sleeping Using an External Display
Things you required: An external display or projector, wired or wireless mouse and keyboard, and charging adapter.
- Plug in the charging adapter to your MacBook
- Connect (or pair) an external mouse and keyboard
- Connect a monitor or projector to your MacBook
- If you use wireless mouse and keyboard, click on the Apple logo → System Preferences.
- Click on Bluetooth.
- Now, click on Advanced.
- Make sure tick the box for Allow Bluetooth devices to wake this computer and then click on OK.
- You will see your MacBook’s screen on the external display. Go ahead and close the MacBook’s lid.
Now, the screen on the external monitor may flash or even turn off. To fix this, press any key on the connected keyboard or shake your mouse. The screen will turn back on.
Note: In step 1, I asked you to connect your MacBook to a power source. But if you have a compatible monitor like the LG UltraFine 5K, then there is no need to do so as it will also simultaneously charge your MacBook with the same single cable.
