MacBook Sleep Settings Guide – Keep Your Mac from Going to Sleep

Posted By Volodymyr Chubei | 16 Jan 2026

In this article, we'll explore how to manage MacBook sleep settings and customize your device's operation in sleep mode. You'll learn how to adjust sleep time on your Mac , change screen-off settings, create a custom sleep timer, and fully control your MacBook's hibernation behavior—manually or through System Preferences.

Putting MacBook to sleep manually

There are several ways to manually put your MacBook into sleep mode:

via the Apple menu: select Sleep;
By closing the laptop lid, the device will automatically go into sleep mode;
using the keyboard shortcut: Control+Shift+Power (or Control+Shift+Eject on older models with a drive).

Older Macs, manufactured before 2012, also used IR ports and Apple Remotes: sleep mode could be initiated with the Play/Pause button, and wake mode could be activated by pressing any key. These features are no longer supported in modern versions of macOS, as the system uses different sleep mode management methods—they are described in the section on how to change sleep settings on Mac.

How to change MacBook sleep time setting

You can automatically put your MacBook into sleep mode after a set period of time — from one minute to three hours of inactivity. You can also disable this switch completely — this feature is useful for long-running tasks and is available in the " How to turn off auto sleep on Mac" settings.

Open System Settings (or System Preferences in macOS Monterey and earlier) and go to the Battery section.

In the Turn display off on battery power field, set the time after which the screen turns off when running on battery power.
Turn on Prevent automatic sleeping when the display is off if you want your Mac to continue running in the background when the screen is off.
Enable Wake for network access to allow your Mac to wake when accessed by other devices on the network.
Some models have an Enable Power Nap option, which allows the system to perform background tasks while sleeping (such as checking email).
If necessary, enable Optimize video streaming while on battery—it reduces video quality to save battery (not available on all devices).

After that, you can set parameters for using the power adapter in the same Options menu. The "Prevent automatic sleeping when the display is off" and "Wake for network access" options are available for both battery and AC power—simply set the needed parameters in each mode. In the "Turn display off on power adapter" field, specify the number of minutes after which the screen should turn off. This applies to the Mac's "sleep after x minutes" setting.

How to create a MacBook sleep timer

If you know in advance when you will not use your MacBook, you can set up automatic sleep mode in advance. For example, you can set the sleep time to midnight to prevent the device from running all night without any purpose. This approach is useful when configuring MacBook sleep settings , especially when you need to understand how to set the sleep timer on your MacBook and optimize battery life without constant manual monitoring.

Setting up a timer via Schedule:

Open System Settings (in macOS Monterey and earlier, System Preferences).
Go to the Battery section and select Schedule (or Schedule if the interface is in Russian).
Enable the Sleep option, specify the day of the week and the exact time when you want your Mac to go to sleep.
Click OK to save.

In macOS Ventura and newer OS, the Schedule block may be located separately in the Battery section. In older versions, it was located in the Power Adapter tab.

If you want to manually set the shutdown timer via Terminal, you can use the command:

sudo shutdown -h +30

Where +30 is the number of minutes before shutdown.

Detailed instructions on setting up sleep for your version of macOS are available at official Apple help.

If your Mac has trouble sleeping or lags, it's often due to an overflowing cache and background services. To restore stable performance, we recommend using CleanMyMac X, a utility that removes temporary files, frees up system resources, and disables unnecessary background processes.
