Are you frustrated with your MacBook Pro not turning off when you close the lid? You’re not alone. Many MacBook Pro users have reported this issue, and it can be caused by a variety of factors. In this article, we’ll explore the possible reasons why your MacBook Pro won’t turn off when closing the lid and provide you with step-by-step solutions to resolve the issue.
Understanding the MacBook Pro’s Sleep Mode
Before we dive into the possible causes and solutions, it’s essential to understand how the MacBook Pro’s sleep mode works. When you close the lid of your MacBook Pro, it’s supposed to go into sleep mode, which is a low-power state that helps conserve battery life. In sleep mode, your MacBook Pro’s screen turns off, and the computer becomes unresponsive. However, the computer is still running in the background, and it can wake up quickly when you open the lid or press a key.
Why Won’t My MacBook Pro Turn Off When I Close the Lid?
There are several reasons why your MacBook Pro might not be turning off when you close the lid. Here are some possible causes:
- Incorrect Settings: If your MacBook Pro’s settings are not configured correctly, it might not turn off when you close the lid. For example, if you have set your MacBook Pro to never sleep when the lid is closed, it will remain on even when you close the lid.
- External Devices: If you have external devices connected to your MacBook Pro, such as a USB drive or an external monitor, it might prevent your MacBook Pro from turning off when you close the lid.
- Resource-Intensive Programs: If you have resource-intensive programs running in the background, such as video editing software or games, they might prevent your MacBook Pro from turning off when you close the lid.
- Software Issues: Software issues, such as a corrupted operating system or a faulty app, can also prevent your MacBook Pro from turning off when you close the lid.
- Hardware Issues: Hardware issues, such as a faulty lid sensor or a malfunctioning logic board, can also cause this problem.

Why won’t my MacBook Pro turn off when I close the lid?
Your MacBook Pro may not be turning off when you close the lid due to a setting that prevents it from sleeping or shutting down when the lid is closed. This setting is usually enabled when an external display or power source is connected to the MacBook. To resolve this issue, you need to check your MacBook’s settings and adjust them accordingly.
You can start by going to System Preferences, then Energy Saver, and checking the settings for what happens when the lid is closed. If you’re using an external display or power source, try disconnecting them and see if the issue persists. Additionally, you can try resetting the System Management Controller (SMC) and the Power Management Unit (PMU) to restore the default settings.
How do I reset the System Management Controller (SMC) on my MacBook Pro?
Resetting the SMC on your MacBook Pro can resolve issues related to power management, including the MacBook not turning off when the lid is closed. To reset the SMC, start by shutting down your MacBook. Then, locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button. Press these keys simultaneously and hold them for 10 seconds.
Release the keys and press the Power button again to turn on your MacBook. This will reset the SMC and restore the default settings. Note that resetting the SMC will not affect your data or settings, but it may change some of the default behaviors of your MacBook. If you’re still experiencing issues after resetting the SMC, you may need to try other troubleshooting steps.
What is the Power Nap feature, and how does it affect my MacBook’s sleep mode?
The Power Nap feature on your MacBook Pro allows it to periodically wake up and update itself while it’s in sleep mode. This feature is enabled by default and can cause your MacBook to wake up and perform tasks even when the lid is closed. If you’re experiencing issues with your MacBook not turning off when the lid is closed, you may want to consider disabling the Power Nap feature.
To disable Power Nap, go to System Preferences, then Energy Saver, and uncheck the box next to “Enable Power Nap while on battery power” or “Enable Power Nap while on power adapter.” Disabling Power Nap will prevent your MacBook from waking up periodically, but it may also prevent it from receiving updates and syncing data while it’s in sleep mode.
Can I use the ‘Close the lid’ option in the Energy Saver settings to turn off my MacBook Pro?
Yes, you can use the “Close the lid” option in the Energy Saver settings to turn off your MacBook Pro when the lid is closed. To do this, go to System Preferences, then Energy Saver, and select the “Close the lid” option from the dropdown menu next to “When the lid is closed.” This will put your MacBook to sleep when the lid is closed, but it may not turn it off completely.
If you want to turn off your MacBook Pro completely when the lid is closed, you may need to use a third-party app or script that can override the default settings. Alternatively, you can try using the “Shutdown” option in the Apple menu when you’re ready to turn off your MacBook.
How do I troubleshoot issues with my MacBook Pro’s sleep mode?
To troubleshoot issues with your MacBook Pro’s sleep mode, start by checking the Energy Saver settings to ensure that the “Close the lid” option is selected. You can also try resetting the SMC and PMU to restore the default settings. Additionally, you can check for any software updates and install the latest version of macOS.
If you’re still experiencing issues, you can try using the Activity Monitor app to see if any processes are preventing your MacBook from sleeping. You can also try disconnecting any external devices and see if the issue persists. If none of these steps resolve the issue, you may need to contact Apple support for further assistance.
Can I use a third-party app to turn off my MacBook Pro when the lid is closed?
Yes, there are several third-party apps available that can turn off your MacBook Pro when the lid is closed. These apps can override the default settings and provide more control over your MacBook’s sleep mode. Some popular options include SleepWatcher, AutoSleep, and LidSleep.
When using a third-party app, make sure to follow the instructions carefully and adjust the settings according to your needs. Keep in mind that using a third-party app may void your warranty or cause compatibility issues with other apps. Always read reviews and check the app’s compatibility before installing it on your MacBook.
What should I do if my MacBook Pro is not turning off when the lid is closed and I’ve tried all the troubleshooting steps?
If you’ve tried all the troubleshooting steps and your MacBook Pro is still not turning off when the lid is closed, you may need to contact Apple support for further assistance. You can visit the Apple Support website, call the Apple Support hotline, or visit an Apple Store in person.
When contacting Apple support, be prepared to provide detailed information about your MacBook Pro, including the model number, macOS version, and any error messages you’ve encountered.
