Change Sleep Time on Mac

Mac computers have a cool feature called sleep mode that helps save energy and extend battery life. It’s a smart way of powering down non-essential parts while keeping your active tasks intact. Sleep mode strikes a balance between efficiency and convenience. In this article, we’ll dive into Mac’s sleep settings, explaining how they work and how you can customize them. Whether you want to fine-tune power management or personalize your Mac’s behavior, understanding sleep settings is key. Let’s explore how you can make the most of this feature.

Understanding Mac Sleep Settings

Mac computers come with sleep mode to optimize power consumption and battery life. When your Mac goes into sleep mode, it shuts down unnecessary components while preserving the state of active tasks. Let’s learn more about sleep mode on Mac and how you can customize the settings to your liking.

What is Sleep Mode on a Mac?

Sleep mode, also known as standby, is a power-saving state that kicks in when your Mac is not in use. It turns off the display, stops background processes, and puts the hard drive to sleep. But it keeps the system memory powered so that you can quickly resume your work when you wake it up.

Default Sleep Settings and Their Purpose

By default, Mac computers are set to enter sleep mode after a certain period of inactivity. The exact settings vary depending on your Mac model and macOS version, but the general aim is to find a balance between conserving power and convenience.

Here are some default sleep settings and what they do:

  1. Display Sleep: This setting determines how long your Mac’s screen stays idle before it turns off to save power. You can adjust it to your liking. To change the display sleep time, go to System Settings > Energy Saver and adjust the “Turn display off after” slider.
  2. Computer Sleep: This setting determines how long your Mac waits before entering a deeper sleep state. It conserves more power by reducing system activity. To change the computer sleep time, go to System Settings > Energy Saver and adjust the “Put the computer to sleep when it is inactive for” slider.

By customizing these sleep settings, you can make your Mac sleep the way you want. If you prefer a longer awake time before sleep, increase the sleep time. If you want to save power more aggressively, decrease it.

Remember that changing sleep settings may affect your Mac’s performance and battery life. So find the right balance that suits your power-saving needs while keeping a smooth user experience.

Overall, understanding and adjusting sleep settings on your Mac can help you optimize power usage, prolong battery life, and personalize your computer’s behavior.

    Replace “[time in minutes]” with your desired duration, like 60 for 1 hour. Press Enter to execute the command.adjust sleep time on mac using terminal

Keep in mind that using Terminal commands requires administrative privileges, and modifying certain system settings can have unintended consequences if done incorrectly. So always double-check the commands and their effects before executing them.

By following either of these methods, you can easily change the sleep time on your Mac and fine-tune its power management to suit your preferences and workflow.

Advanced Sleep Settings and Customization Options

When it comes to managing your sleep preferences on a Mac, there are various advanced settings and customization options available. These options allow you to tailor your sleep settings to your specific needs and save power when your device is not in use. Let’s explore some key features and how you can make the most of them.


Hibernation is another sleep-related feature that allows your Mac to save its current state to the hard drive before entering a low-power mode. It ensures that when you turn on your Mac after hibernation, you can resume your previous session exactly as you left it.

By default, Mac computers don’t hibernate. However, if you want to enable hibernation, you can use the following command in the Terminal:

sudo pmset -a hibernatemode 25

Enabling hibernation can be useful if you frequently need to preserve your work across extended periods of inactivity or if you want to conserve battery power for an extended period.advanced mac sleep settings

Additional Tips for Sleep Management

In addition to the existing information on sleep management for Mac, here are some additional tips and tricks to further optimize your sleep settings:

  1. Disable Wake for Network Access: By default, Mac computers are set to wake up when accessed over the network. If you don’t need this feature, you can disable it to prevent unnecessary wake-ups. Go to System Settings > Energy Saver > Wake for network access, and uncheck the box.
  2. Avoid Using Power Nap: Power Nap allows your Mac to perform certain tasks, like receiving emails and performing backups, even while it’s asleep. But if you want to save power and reduce sleep disruptions, you can consider disabling Power Nap. To do this, go to System Settings > Energy Saver and uncheck the “Enable Power Nap” option.
  3. Close Network-Intensive Applications: Before putting your Mac to sleep, make sure to close network-intensive applications like file-sharing programs or cloud-syncing services. These apps can prevent your Mac from entering sleep mode or cause frequent wake-ups.
  4. Check Activity Monitor: Use the Activity Monitor utility to identify any processes or applications that might be preventing your Mac from entering sleep mode. Look for high CPU or network usage and close or troubleshoot the problematic apps accordingly.
  5. Avoid Scheduling Conflicts: If you have scheduled tasks like Time Machine backups or software updates, ensure they don’t run during your preferred sleep times. Conflicting schedules can interrupt sleep mode and impact power management.

By incorporating these additional tips, you can optimize sleep mode on your Mac, ensuring efficient power usage and a personalized experience.


In conclusion, Mac’s sleep mode is a powerful tool for optimizing energy usage and personalizing user experience. By adjusting sleep settings, such as display sleep and computer sleep, users can strike a balance between conserving power and maintaining convenience. Advanced features like hibernation and Power Nap offer additional customization options for power management and background tasks. Troubleshooting sleep issues by updating software, checking power sources, and resetting system components can resolve potential problems. By incorporating these tips and understanding the sleep settings on Mac, users can maximize energy efficiency, extend battery life, and create a tailored experience that suits their individual needs.
