One of the flip sides of using a Mac with an external monitor is that it goes to sleep when you close the lid. So you have to keep the lid open or connect your Mac to a charger all the time. Both of these scenarios aren’t ideal. If this is an issue you face regularly, fret not because there’s a simple fix! Here’s how you can prevent your MacBook from sleeping when you close the lid.
Why Should You Prevent Your Mac from Sleeping
One of the most popular use cases for keeping the Mac awake even with the lid closed is when it’s connected to an external monitor. Keeping the MacBook’s lid open at all times in such a scenario can be distracting as you will have two screens to look at. It can also drain the battery rather quickly.
The second use-case for keeping your Mac awake with the lid closed is for when you’re downloading large files. If you’re downloading a file that will take a few hours to complete, it’s a good idea to close the lid while keeping it awake so that the download can take place seamlessly. You can also use this as a simple trick to keep your Mac from sleeping when it is sitting idle. You don’t want your MacBook to go to sleep in the middle of a presentation!
Installing and Setting up Amphetamine
Unfortunately, there is no built-in app or feature on macOS from preventing the Mac from sleeping. There’s a third-party app to acheive that – Amphetamine. Get Amphetamine It’s free to download from the App Store and does not have any ads. It’s lightweight, non-intrusive, and works as intended. Step 1: Download Amphetamine from the App Store on your Mac. Once done, tap on ‘Open.’
Step 2: You will now see a circular icon on your Mac’s menu bar that looks like a pill. Click on it.
Step 3: Hover your mouse over ‘Quick Preferences’ and uncheck the box next to ‘Allow system sleep when display is closed’.
Step 4: Doing this will trigger a pop-up asking you to install Amphetamine Enhancer. This is a fail-safe app that will ensure your Mac doesn’t go to sleep when the lid is closed. Click on ‘Get Amphetamine Enhancer’.
Download Amphetamine Enhancer
Step 6: Double-click on the downloaded .dmg file to run it. You will now see a Finder window open up. Drag the ‘Amphetamine Enhancer.app’ icon into the ‘Applications’ icon. Once done, close the Finder window.
Step 7: Open the ‘Applications’ folder on Finder and double-click on Amphetamine Enhancer to run the installer.
Step 8: Click on ‘Open’ when prompted.
Step 9: In the installer window, select ‘Closed-Display Mode Fail-Safe’ in the left column and click on ‘Install.’ Close the installer once done.
Amphetamine is now set up on your MacBook. This is a one-time process.
How to Keep Your Macbook Awake With the Lid Closed
Now that Amphetamine is up and running on your Mac, here’s how you can prevent your Mac from going to sleep with the lid closed. Step 1: Click on the pill-shaped icon on the menu bar to open Amphetamine.
Step 2: Click on ‘Indefinitely’ to start a new session. Your Mac will now stay awake even with the lid closed for an indefinite period until you end the session manually.
Step 3: To end a session, tap on the pill icon again and select ‘End current session’.
Step 4: You can also run the app for a set duration. This will keep your Mac awake for that particular duration. Instead of selecting ‘Indefinitely’, select the required ‘Minutes’ or ‘Hours’ option from the menu.
If you’ve selected the ‘Indefinitely’ option, make sure to end your session once you’re done using your MacBook. Or else, your Mac will not sleep and it will end up draining the battery completely.
How to Start an Amphetamine Session at Startup
If you want your MacBook to stay awake and not sleep each time you turn it on, you can enable it to start a session each time you log in. Here’s how to do it. Step 1: Click on the pill-shaped icon on the menu bar to open Amphetamine.
Step 2: Select the ‘Preferences’ option.
Step 3: Check the boxes next to ‘Launch Amphetamine at login,’ ‘Start session when Amphetamine launches,’ and ‘Start session after waking up from sleep.’
Step 4: Close the window, and you’re good to go. Each time you turn on your MacBook, Amphetamine will automatically launch and start a session.
