    How to Keep Macbook From Sleeping

    Your MacBook’s sleep feature is designed to conserve energy and extend battery life, but there are scenarios where you might want to keep it awake for an extended period. If you are doing a presentation, downloading big files, or running tasks in the background, it’s important to know how to keep MacBook from sleeping. To make sure your MacBook stays awake when you need it to, we’ll go over a number of ways to modify its default sleep settings in this comprehensive guide.

    Understanding MacBook Sleep Settings

    Before diving into methods to prevent your MacBook from sleeping, it’s essential to understand the default sleep settings. MacOS is designed to put your MacBook to sleep after a certain period of inactivity to conserve battery life. To suit your needs, you can adjust these options.

    Adjusting Sleep Settings

    Navigate to “System Preferences” on your MacBook.

    Select “Energy Saver.”

    Adjust the “Turn display off after” and “Put hard disks to sleep when possible” sliders according to your preferences. While this won’t keep your MacBook entirely awake, it will delay sleep.

    Using Caffeine, a Third-Party App

    Caffeine is a popular third-party app that prevents your MacBook from going to sleep. Follow these steps:

    Download and install Caffeine from the App Store.

    Launch the app from your menu bar.

    Click on the coffee cup icon to activate Caffeine, preventing your MacBook from sleeping.

    Terminal Commands for Temporary Wakefulness: If you prefer a more hands-on approach, Terminal commands can be used to temporarily override sleep settings. Open Terminal and enter the following command:


    Your MacBook will stay awake until you manually interrupt the command.

    Setting Up a Hot Corner:

    Go to “System Preferences” > “Desktop & Screen Saver.”

    Click on the “Screen Saver” tab.

    Choose the “Hot Corners” option.

    Assign a corner to “Disable Screen Saver” or “Start Screen Saver” to keep your MacBook awake when the cursor is in that corner.

    Playing a Video in Full Screen

    Playing a video in full screen, either through a media player or a web browser, can keep your MacBook awake. This is a helpful way to stay awake for a long time when you need to.

    Using Terminal for Persistent Wakefulness

    To keep your MacBook awake for an extended period, use Terminal with the following command:

    caffeinate -t [time in seconds] 

    Replace [time in seconds] with the desired duration. This command will prevent sleep for the specified time.

    Preventing Sleep When Closing the Lid

    Navigate to “System Preferences” > “Energy Saver.”

    Uncheck the box next to “Put hard disks to sleep when possible.”

    Close the lid while your MacBook is connected to an external display and power source to keep it awake.

    Using Third-Party Apps for Customization

    Explore third-party apps like Amphetamine or InsomniaX for more advanced customization options. These apps can change your MacBook’s settings so it stays on when you want it to.

    Disabling Power Nap: Power Nap is a feature that allows your MacBook to perform certain tasks even when asleep. While useful, it might interfere with your efforts to keep the MacBook awake. To disable Power Nap:

    Go to “System Preferences” > “Energy Saver.”

    Uncheck the box next to “Enable Power Nap.”

    Creating Automator Workflows

    Automator, a built-in app on your MacBook, allows you to create custom workflows. Follow these steps:

    Open Automator and choose “Application” as the document type.

    Search for the “Prevent Computer Sleep” action.

    Drag this action to the workflow.

    Save the application and run it when you want to prevent sleep.

    Adjusting System Preferences for Media Playback

    Certain media applications, such as iTunes, have settings to prevent sleep during playback. Check the preferences of your media player to enable this feature.


    In simple terms, if you know how to keep your MacBook from sleeping, you can use it for a longer time and in more places. If you are using your MacBook for a presentation, downloading big files, or doing other tasks, these methods let you choose when your MacBook goes to sleep and when it stays on. Try different options to see which one is the best for you and the way you like to do things. You have greater control over how you use your MacBook since you know how to adjust its sleep settings. That MacBook of yours is one strong machine.
