How to fix Sleep Mode not working on Mac? If your Mac does not sleep, it could be because of some apps or items interfering with the process. This may shorten the life of your Mac because sleep mode saves energy when it is not in use. Here are some tried-and-true techniques to ensure your Mac goes to sleep without a hitch.

Other important situations that require your immediate attention may arise while using your Mac. To prevent closing certain programmes, put your macOS into hibernation or sleep mode so that you may pick up where you left off when you return. When you return to your Mac and wake it up, the system may refuse to respond to key inputs and hence will not wake from sleep.

Here is the list of 9 methods to fix Sleep Mode not working on Mac:

Method #1. Check that your Mac’s sleep settings are right

After the specified time, your Mac goes to sleep. However, if you have it set to sleep after a long period of time (say, 3 hours) or Never, you can modify it using the instructions below.

  1. Select System Preferences from the Apple menu at the upper left.
  2. Click Energy Saver on a Mac desktop and MacBook running macOS Catalina or older. Click Battery on a MacBook running macOS Big Sur. On MacBooks, select the Battery tab (and then the Power Adapter tab).
  3. Check that neither Computer Sleep nor Display Sleep is set to Never.

Method #2. Quit apps designed to prevent Mac’s sleep

Third-party apps like Amphetamine, Owly, and Anti Sleep that hinder your Mac from napping could be one of the main reasons your MacBook doesn’t sleep. When you turn on your Mac, these apps may start automatically and prevent it from sleeping.

To resolve this, go to the Launchpad or Applications folder in Finder and ensure that no such apps are present. Even if you decide to keep such an app, open it and disable any options that enable it automatically.

Method #3. Stop Bluetooth devices from waking your Mac

There is an option in Mac’s Bluetooth settings that automatically wakes the machine. If you use a Bluetooth mouse, keyboard, or trackpad, for example, hitting a button will wake the Mac. This is a useful setting, but you can disable it if necessary.

  1. Open System Preferences and click Bluetooth.
  2. From the lower right, select Advanced.
  3. Uncheck Allow Bluetooth devices to automatically wake this computer.

Method #4. Check Mac’s sharing preferences

You can share resources with other users, such as the connected printer, shared files, and so on. This, however, wakes up your Mac. You can avoid this by turning off the sharing options.

  1. Click Sharing in System Preferences.
  2. Uncheck any services that you do not require.

Method #5. Use Activity Monitor to fix Sleep Mode not working on Mac

Activity Monitor allows you to keep track of which apps are consuming CPU and other resources. If you notice an app consuming unusually large amounts of resources in the background, close it since it could be the reason stopping your Mac from resting.

  1. To open it, press Command + Space Bar and type Activity Monitor.
  2. Select the strange app and then click the cross (x) symbol in the upper left corner.
  3. Select Quit (recommended) or Force Quit (if Quit fails).

Method #6. Disconnect peripherals to fix Sleep Mode not working on Mac

Externally connected hardware, such as a defective hard disc, pen drive, or similar device, may prevent the Mac from sleeping. To ensure Mac sleeps, disconnect all of them. Alternatively, utilise the trial technique to determine the external device causing the issue. Replace it or make sure the malfunctioning peripheral is not left attached for an extended period of time.

Method #7. Reset the NVRAM and SMC to fix Sleep Mode not working on Mac

Finally, if nothing else works, reset the NVRAM or PRAM. We have a separate guide that goes through everything and how to begin. You can also go ahead and reset Mac’s SMC. Again, all details can be found in the linked post.

Method #8. If Spotlight is indexing files Mac won’t sleep

Spotlight Search (accessible by pressing Command + Space Bar) is one of the best features of the Mac (and iPhone), and I (and you) use it every day. This is a simple way to discover files, open apps, perform basic arithmetic and conversions, and much more.

Your Mac will not sleep while Spotlight is indexing data on the internal storage. It could take many hours depending on the number of files. Indexing occurs primarily after you set up your Mac, upgrade macOS, change your hard disc, and so on. It may also occur when a large number of new files are added. From the menu bar’s upper right, select the search symbol. If Spotlight is indexing files, a progress bar and the text ‘Indexing’ will appear.

Method #9. Hardware problem

When you close your MacBook’s lid, the magnets tell it it’s time to sleep. Though improbable, if you have a strange cover or something like that, this could be hampered.

Furthermore, if your MacBook was dropped, there may be hardware difficulties in the lid that prohibit it from sleeping when you close it. In these cases, click the Apple logo and select Sleep.

Finally, there could be issues with the wire connecting the motherboard to which these instructions are sent. Again, this will only happen in exceptional circumstances. However, if none of the above remedies works, contact Apple Support to learn about your repair options.
