Adjusting Mac Sleep Settings: A Quick Guide

how to change time it takes for mac to sleep

If you want to change the amount of time it takes for your Mac to go to sleep, you can do so by adjusting your system settings. By default, your Mac is set to turn off its display and enter sleep mode after a few minutes of inactivity to conserve power. However, you can extend or reduce this automatic sleep time by going into your System Settings and selecting Lock Screen from the left sidebar. From there, you can adjust the Turn display off when inactive settings. Depending on your macOS version, you may find these settings under Battery or Energy Saver instead.

Using System Preferences

To change the time it takes for your Mac to go to sleep, you can use the System Preferences on your device. Here is a step-by-step guide:

Step 1: Access System Preferences

Click on the Apple logo in the upper-left corner of your screen to access the System Preferences.

Step 2: Select Battery or Energy Saver

Depending on your macOS version, you may need to select different options. For MacBook users, go to System Preferences and select 'Battery'. Older macOS versions, such as macOS Monterey and earlier, also have the option to select 'Energy Saver'. If you are using a Mac desktop, the 'Energy Saver' option is recommended.

Step 3: Adjust Sleep Settings

In the Battery or Energy Saver settings, you will find various options to adjust your Mac's sleep behaviour.

  • Turn Display Off After: Use the slider to choose how long your MacBook should wait before putting the display to sleep. You can select anywhere from one minute up to three hours, or you can drag the slider to Never if you don't want the display to turn off automatically.
  • Prevent Computer from Sleeping Automatically: Tick the box next to "Prevent computer from sleeping automatically when the display is off" to keep your Mac awake even when the display is off.
  • Wake for Network Access: Allow your Mac to wake up and perform background tasks like updating apps or receiving messages while it's asleep.
  • Schedule Sleep Times: If you want to put your Mac to sleep at a specific time, click on Schedule in the Battery settings. From here, you can select the day of the week and the exact time you want your Mac to go to sleep.

By following these steps, you can customise the sleep settings on your Mac according to your preferences.

Adjusting the 'Turn display off after' slider

Adjusting the "Turn display off after" slider will allow you to choose how long your MacBook waits before putting your display to sleep. The slider offers a range of times from one minute up to three hours, or you can slide it to the right if you never want the display to turn off.

  • Click on the Apple logo: Click on the Apple icon located in the upper-left corner of your screen.
  • Select System Preferences: Once the Apple menu is open, select "System Preferences".
  • Choose Energy Saver or Battery: Depending on your macOS version, you may need to select "Energy Saver" or "Battery". For older versions of macOS, you may find the setting under "Battery" or "Energy Saver".
  • Adjust the slider: In the "Energy Saver" or "Battery" settings, you will find the "Turn display off after" slider. Move the slider to your preferred duration before your display goes to sleep.

Please note that the "Turn display off after" slider controls the time it takes for your display to turn off due to inactivity. If you want to prevent your Mac from automatically sleeping when the display is off, you can enable the "Prevent automatic sleeping when the display is off" or "Prevent computer from sleeping automatically when the display is off" setting. This will keep your Mac awake even if the display is turned off.

Using Terminal

If you want to change the time it takes for your Mac to go to sleep, you can do so by using the Terminal app. Here's a step-by-step guide on how to do it:

First, go to Applications > Utilities to open the Terminal app. Then, enter the following command, but don't hit Return yet: "pmset sleep". After that, add a space, and then type one of the following modifiers: "+" to set a timer, "-" to cancel a timer, or "=" to check the current settings.

Next, add another space, and then type "+" followed by the number of minutes you want to set the timer for. For example, if you want to put your Mac to sleep after 30 minutes, you would type "+30".

Finally, hit Return to start the timer. Your Mac will now go to sleep automatically after the specified amount of time. Note that you will need to enter an administrator's password to confirm the command.

By default, a Mac goes to sleep after two minutes of inactivity. However, you can set different periods of time ranging from one minute to three hours of inactivity.

Additionally, if you have a MacBook with an IR port, you can also use the Apple Remote to put your MacBook to sleep after a specified period. Press and hold the Play/Pause button for five seconds to activate sleep mode, and press any button on the remote to wake it up.

Keep in mind that the sleep/wake and energy-saving settings on Mac can vary between different versions of macOS. Earlier versions may have separate sliders for display sleep time and computer sleep time.
