How to Turn Off Sleep Mode on a Mac

Turning off sleep mode on a Mac involves adjusting the power settings to prevent the system from automatically entering sleep mode. By disabling sleep mode, you can keep your Mac awake and prevent it from going into a low-power state, allowing uninterrupted use and eliminating the need to wake it up repeatedly. Whether you need to work on tasks that require continuous activity or want to prevent interruptions during presentations or downloads, understanding how to turn off sleep mode on a Mac gives you greater control over your device’s power management.

What is sleep mode on Mac?

Sleep mode on a Mac is a power-saving feature that automatically puts the computer into a low-power state after a period of inactivity. When a Mac enters sleep mode, it suspends most of its operations to conserve energy while maintaining the current state of the system. The display turns off, and the computer goes into a sleep state, consuming minimal power. This allows the Mac to quickly resume normal operation when awakened, with open applications and files in the same state as before entering sleep mode. Sleep mode helps extend battery life on laptops and reduces energy consumption on desktop computers when they are not actively being used.

How to Turn Off Sleep Mode on a Mac?

To turn off sleep mode on a Mac and prevent it from automatically entering a low-power state, you can adjust the power settings using the following steps:

  1. Click on the Apple menu in the top-left corner of the screen and select “System Preferences.”
  2. In the System Preferences window, click on “Energy Saver.”
  3. In the Energy Saver settings, you will see two tabs: “Battery” and “Power Adapter.” Depending on whether your Mac is connected to a power source or running on battery, choose the appropriate tab.
  4. Adjust the slider for “Computer Sleep” or “Turn display off after” to a longer duration or select “Never” if available. This will prevent your Mac from automatically going to sleep or turning off the display after a specific period of inactivity.
  5. Optionally, you can uncheck the option “Put hard disks to sleep when possible” to ensure that the hard disks stay active even when the Mac is idle.
  6. Close the Energy Saver preferences window.

By following these steps, you have successfully turned off sleep mode on your Mac. However, keep in mind that leaving your Mac awake for extended periods may drain the battery faster on laptops or increase power consumption on desktop computers. It’s recommended to adjust the settings according to your specific needs to balance power-saving and performance requirements.

Use Third-Party Apps to Stop Your Mac From Going to Sleep

There are several third-party apps available that can help you prevent your Mac from going to sleep. Here are a few popular options:

  1. Amphetamine: Amphetamine is a free app available on the Mac App Store. It provides a simple and intuitive interface to keep your Mac awake. You can set different triggers and durations for keeping your Mac awake, such as specific applications running or certain conditions met.
  2. Caffeine: Caffeine is another popular free app that prevents your Mac from sleeping. It adds a small coffee cup icon to your menu bar, and when activated, it temporarily disables the sleep settings and keeps your Mac awake. Simply click on the icon to toggle it on or off.
  3. KeepingYouAwake: KeepingYouAwake is a free and open-source app inspired by Caffeine. It offers a similar functionality, allowing you to toggle the sleep prevention feature from the menu bar. It also provides additional features like custom hotkey support.
  4. InsomniaX: InsomniaX is a more advanced option that allows you to control sleep settings in greater detail. It provides different modes, such as Insomnia mode, which keeps your Mac awake until you manually turn it off, or Lid Sleep mode, which prevents sleep when you close the lid of your MacBook.

To use any of these apps, simply download them from their respective websites or the Mac App Store, install them, and launch the app. Follow the instructions provided by each app to set your preferences and prevent your Mac from going to sleep.

Remember to use such apps responsibly and only when necessary, as keeping your Mac awake for extended periods can impact energy consumption and potentially lead to overheating.

Don’t Let Your Mac Sleep

To prevent your Mac from going to sleep entirely, including disabling both the display sleep and system sleep, you can use the “Caffeine” utility. Caffeine is a third-party application that keeps your Mac awake for a specified period or indefinitely. Here’s how you can use it:

  1. Visit the Caffeine website (https://intelliscapesolutions.com/apps/caffeine) using your web browser.
  2. Download the latest version of Caffeine by clicking on the “Download” button.
  3. Once the download is complete, locate the Caffeine.dmg file in your Downloads folder and double-click on it to mount the disk image.
  4. In the mounted disk image, you’ll find the Caffeine.app file. Drag and drop this file into your Applications folder to install the application.
  5. Open the Caffeine app by either launching it from the Applications folder or searching for it using Spotlight (press Command + Spacebar and type “Caffeine”).
  6. The Caffeine app will appear as a coffee cup icon in your menu bar.
  7. Click on the coffee cup icon in the menu bar to activate Caffeine. When activated, the coffee cup will be full, indicating that sleep mode is disabled.
  8. By default, Caffeine will prevent your Mac from sleeping indefinitely. If you want to set a specific duration for Caffeine to keep your Mac awake, click on the coffee cup icon again and choose the desired time interval from the options (e.g., 1 hour, until a specific time, etc.).

Now, your Mac will stay awake according to the settings you’ve configured using the Caffeine app. Remember to manually disable Caffeine or adjust the settings when you want your Mac to sleep normally to conserve power or prevent overheating.

How to Temporarily Turn Off Sleep Mode?

If you want to temporarily turn off sleep mode on your MacBook Pro without using third-party software, you can utilize the “caffeinate” command in the Terminal application. Here’s how you can do it:

  1. Open the Terminal application. You can find it in the Utilities folder within the Applications folder, or you can use Spotlight (press Command + Spacebar and type “Terminal”) to search for it.
  2. In the Terminal window, type the following command and press Enter: caffeinate -u -t 3600

This command will prevent your Mac from going to sleep for 3600 seconds (1 hour). You can change the duration (3600) to the desired number of seconds.

  1. As long as the Terminal window is open and the command is running, your Mac will stay awake. You can minimize the Terminal window or continue using your Mac as usual.
  2. Once the specified time has passed, or when you want to allow your Mac to sleep again, return to the Terminal window and press Ctrl + C to stop the caffeinate command. This will restore the normal sleep behavior of your MacBook Pro.

By using the caffeinate command, you can temporarily disable sleep mode on your Mac without installing any additional software.

How to Schedule Sleep Mode on Mac?

  2. Select “System Preferences” from the drop-down menu.
  3. In the System Preferences window, click on “Energy Saver.”
  4. In the Energy Saver settings, you’ll see two tabs: “Battery” and “Power Adapter.” Depending on whether your Mac is connected to power or running on battery, choose the appropriate tab.
  5. Click on the “Schedule” button located at the bottom right corner of the Energy Saver window.
  6. In the Schedule dialog box, check the box next to “Sleep” to enable the sleep schedule.
  7. Choose the desired sleep schedule by clicking on the checkboxes for specific days or options available.
  8. Select the time you want your Mac to go to sleep by clicking on the drop-down menus for “Start” and “End.”
  9. Once you’ve set the sleep schedule according to your preferences, click on the “OK” button to save the changes.

Now, your Mac will automatically enter sleep mode based on the schedule you’ve configured. This feature is particularly useful if you want your Mac to conserve energy or go to sleep during specific hours, such as at night or when it’s not in use.
