MacOS: How to disable Bluetooth while the computer is asleep (lid is closed)?

Bluetooth is a wireless technology that allows you to connect various devices to your Mac, such as keyboards, mice, speakers, and headphones. While Bluetooth can be convenient, it can also drain your Mac's battery when it's not in use. If you want to save battery life by disabling Bluetooth while your Mac is asleep (lid closed), this article will guide you through the process.

Before we begin, it's important to note that the steps described here are for macOS (formerly known as OS X) versions 10.14 (Mojave) and later. If you're using an older version of macOS, the steps may vary slightly.

Step 1: Open System Preferences

To disable Bluetooth while your Mac is asleep, you'll need to access the System Preferences. You can do this by clicking on the Apple menu in the top-left corner of your screen and selecting "System Preferences" from the dropdown menu.

Step 2: Go to Energy Saver

In the System Preferences window, locate and click on the "Energy Saver" icon. This will open the Energy Saver settings.

Step 3: Adjust Power Adapter settings

In the Energy Saver settings, you'll see two tabs: "Battery" and "Power Adapter." Make sure you're on the "Power Adapter" tab.

Next, you'll notice a checkbox labeled "Wake for Wi-Fi network access." This checkbox allows your Mac to wake up from sleep mode when it needs to connect to a Wi-Fi network. Since we want to disable Bluetooth while your Mac is asleep, we need to uncheck this box.

Simply click on the checkbox to uncheck it. Once unchecked, your Mac will no longer wake up from sleep mode to connect to a Wi-Fi network.

Step 4: Save the changes

After unchecking the "Wake for Wi-Fi network access" checkbox, you can simply close the Energy Saver settings window. Your changes will be saved automatically.

Now, whenever you close the lid of your Mac, it will go to sleep and Bluetooth will be disabled automatically. This will help conserve your Mac's battery life.

Step 5: Re-enabling Bluetooth

If you ever want to re-enable Bluetooth while your Mac is asleep, you can simply repeat the steps above and check the "Wake for Wi-Fi network access" checkbox in the Energy Saver settings.

Remember that enabling Bluetooth while your Mac is asleep may result in faster battery drain. So, it's recommended to only enable Bluetooth when you actually need it.

That's it! You now know how to disable Bluetooth while your Mac is asleep (lid closed). By following these steps, you can extend your Mac's battery life and ensure that Bluetooth is only active when you want it to be.
