How to change your Mac’s sleep settings
Apple allows you to automatically put your Mac to sleep after a fixed period of your choice (between one minute and three hours). You can even choose to prevent your Mac from sleeping.
To adjust your Mac’s sleep settings:
1. Click the Apple icon in the upper-left corner of your screen
2. Choose System Preferences
3. Select Battery
4. Here you can control the energy-saving settings for when your Mac is powered by the battery or the power adapter. We’ll explain each of your options below.
In the Battery tab:
1. Use the Turn display off after slider to choose how long your MacBook should wait before putting your display to sleep (from one minute up to three hours). You can also prevent the display from ever going to sleep by dragging the slider all the way to the right
2. Below the slider, set these additional sleep-related settings:
- Slightly dim the display when on battery power: This setting is good for saving energy
- Enable Power Nap while on battery power: This allows your Mac to occasionally wake from sleep to perform tasks such as checking for new emails. If your priority is saving battery, it’s best to uncheck this one
In the Power Adapter tab:
1. Use the Turn display off after slider to choose your preferred amount of time to wait before automatically turning the display off. You can choose between one minute and three hours, or slide all the way to the right if you never want the display to turn off
2. Below this slider, set these additional sleep-related settings:
- Prevent computer from sleeping automatically when the display is off: This way you can close the lid without putting your MacBook to sleep.
- Wake for network access: Allow your Mac to wake up when your Wi-Fi turns on or when an app requests access to the internet.
- Enable Power Nap while plugged into a power adapter: Let your Mac wake from sleep to perform certain tasks, like checking for emails
