How to turn on Bluetooth on a Mac
All modern Mac computers have a built-in Bluetooth module. And this means that it should work without installing any additional software on your machine. When your wireless keyboard or Apple Magic Mouse is not connecting to your computer, first check whether Bluetooth is turned on. Here is how:
- Click the Control Center icon in the menu bar.
- Click Bluetooth in the drop-down menu.
- Turn it on using the toggle button.
Why won’t Bluetooth turn on, and how to fix it?
The reasons why it is not working can be divided into software and hardware problems. If your Bluetooth is turned on, but your computer does not see the device, you need to check the following:
- Check if the device is turned on. This sounds simple; however, you might have forgotten to turn the device on, or the power indicator may be broken.
- Check if the device is charged. AirPods and other gadgets can get discharged faster than you expect.
- Check if your device works with other gadgets (phones, tablets, laptops) that support the connection.
- Check if your Mac connects with other devices.
Try to disconnect all your devices and then reconnect them. Here is how to disconnect them:
- Open Bluetooth Settings in the System Setting widnow.
- Click to disconnect your device.
- Restart your system.
- Open the settings again and connect your devices.
You may not know about these files, and you may never have cared about that. But now you should know that macOS automatically creates so-called .plist files that help the system to manage Bluetooth connections with other devices. Remove these files and let the system update them. This might help you fix issues.
- Open Finder.
- Press the Cmd+Shift+G shortcut.
- In the search field, type ~/Library/Preferences/ByHost and press Return.
- Here, find the com.apple.Bluetooth….plist file and remove it.
- Restart your system.
- Turn on Bluetooth.
4. Reset Bluetooth Often, resetting the module can help you fix issues with the wireless connection to your devices. Depending on which macOS version you have, the steps to do this are different. Here is how to reset the Bluetooth module on Mac:
- Open a built-in Apple application called Terminal.
- Copy and paste the following command in its window: sudo pkill bluetoothd
- Press Return (Enter) on your keyboard.
- Enter your user password and press Return.
- Press the Shift+Option keys and click the Bluetooth icon in the menu bar.
- In the drop-down menu, click Reset the Bluetooth module.
- Confirm by clicking OK.
- Restart your system.
System bugs are possible even on macOS. For example, many users have complained about Bluetooth errors on macOS Monterey, and Apple has already fixed this bug. Please ensure your system is up to date and, if needed, update your system.
- Open System Preferences.
- Click Software Update.
- If you see information that a new version of macOS is available, click the Upgrade/Update button.
NVRAM stands for nonvolatile random-access memory. It stores macOS settings for quick operation tasks. Resetting NVRAM can help you fix many software issues, including Mac Bluetooth problems. Follow the steps below:
