When you leave your Mac idle for long, you expect it go into sleep mode. This not just conserves electricity, it prevents the device from heating up as well. However, what if your Mac doesn’t go into sleep mode as it is supposed to?

It is obvious that something is stopping your Mac from going into sleep, but what? Well, this could be due to a simple to solve underlying problems, such as setting error. The solutions that I am about to disclose could be a lifesaver if your Mac is facing this issue.

How to Fix a Mac That Won’t Sleep

Your Mac won’t automatically go to sleep unless it’s inactive or some setting is stopping it from doing so. Try these basic troubleshooting hacks that will help you to figure out and subsequently solving the issue.

Solution #1: Check The Energy Saver Settings

The most common probability of Mac not going to sleep could be a disturbance in your energy-saving settings.

Step #1. Click on the Apple Icon () and select System Preferences from the drop-down menu.

Step #2. Open Energy Saver and carefully study each setting. These settings might be different in your Mac.

Step #3. The Energy Saver window has two tabs Battery and Power Adapter. Check the display settings in both the tabs.

  • Turn display off after should not be set at never
  • If Turn display off after option set for a more extended period, it delays the sleep time of your Mac. Correct the settings as per your preference
  • Uncheck the Prevent computer from sleeping automatically when the display is off, in the Power Adaptor Tab
  • Uncheck the Wake for Wi-Fi network access, in the Power Adaptor Tab

Note: The macOS Catalina update has an added feature to the Energy Saver, the Enable Power Nap while on battery power (Under Battery tab) and Enable Power Nap while plugged into a power adaptor (Under Power Adaptor tab). The Power Nap setting will enable your Mac to periodically check for new email, calendar or other iCloud updates during its sleep. In addition, when plugged into a power adaptor and sleeping, Mac could also back up using Time Machine.

Step #4. Click on Schedule from the bottom of the page.

At times, macOS won’t go to sleep due to some application running in the background. You can simply press Command (⌘) + Option + Esc to check the applications running on your Mac.

You can either close the app manually or use Force Quit tab on the bottom of the dialogue window to close them. There still might be some internal activities such as iTunes, pending printer jobs, or other external drivers that are stopping Mac from entering sleep mode.

Step #1. Click on Bluetooth icon from the menu bar and click on Open Bluetooth Preferences.

Step #2. In the dialogue box, select Advanced from the bottom of the window.

Step #3. Here uncheck the Allow Bluetooth Devices To Wake this Computer, from the drop-down options. Click on OK and exit the window.

Sleep No More In Macbeth

When a Mac is put to sleep, it enters into a low-power state; wherein the current state is kept in memory, and other parts are shut down. The energy consumption in this state is similar to when your Mac is shut down.

So, even though not sleeping does not affect your Mac’s productivity, it does preserve its battery life and conserves energy when plugged in. In case the options above did not fix the issue, contact Apple.
