Today, Bluetooth is one of the most popular wireless technologies, allowing you to connect two or more devices to perform daily tasks with less hardware. With a wide range of possibilities, it’s completely up to you to decide how to use Bluetooth on Mac — but linking your computer to wireless keyboards, mice, trackpads, and speakers is a good place to start.

Installing Bluetooth devices is usually pretty straightforward: first you turn on Bluetooth on Mac, then you follow a few basic steps to make your device discoverable for connection. But sometimes there’s a catch.

How to turn on Bluetooth on Mac?

Most Macs come with the built-in Bluetooth capability, so all you need to do is make sure it’s turned on:

  1. Go to System Preferences in the Apple menu

  2. Click on Bluetooth

  3. Select Turn Bluetooth On

While you’re at it, tick the box beside the “Show Bluetooth in menu bar” option at the bottom of the screen. The menu-bar Bluetooth icon will serve as a shortcut to indicate if the Bluetooth is on, if any devices are connected, or even if particular device’s battery is low.

Connecting Bluetooth devices to Mac

Now that you know how to connect to Bluetooth on Mac, your computer is ready to get in touch with other devices. The process of establishing a connection between a specific device and your Mac is called pairing. Pairing makes other devices recognizable by your Mac and allows for easy automatic connections to be made.

The good news is that Bluetooth devices that came with your Mac are already pre-paired and should connect automatically when turned on. In case you’ve bought an Apple Bluetooth device separately, here’s how to pair it with your Mac:

  1. Connect the device to you Mac using a cable (if available)

  2. Turn the device on

  3. Go to System Preferences ➙ Bluetooth ➙ Turn Bluetooth On

  4. After the device pairs with your Mac, it will appear in the list of available devices ➙ click Connect

  5. When the device is charged, unplug it for wireless use

When connecting non-Apple Bluetooth devices, the key is to enable pairing or discoverable mode on the device in question. The exact way to do this will vary, so check the instructions from the manufacturer first. As a rule, devices only stay in discoverable mode for a few minutes — to save the battery. So hurry up!

How to connect Bluetooth headphones to Mac?

In most ways, Bluetooth headphones are no different than other Bluetooth-enabled devices. Start by making sure your Bluetooth headphones are charged and in discoverable mode. After that you’re just a few clicks away from having them connected to your Mac:

  1. Go to System Preferences

  2. Click on Bluetooth ➙ Turn Bluetooth On

  3. On the right you’ll see a list of devices. When your headphones show up ➙ click Connect

The same steps can be followed if you wonder how to connect Mac to Bluetooth speaker.

Solve Magic Mouse not connecting to Mac Bluetooth

Connecting your Magic Mouse to MacBook Bluetooth is identical to connecting Bluetooth headphones. Simply follow the steps described above and everything should work out just fine.

  • Make sure it’s on

  • Try restarting it

  • Click the mouse button to see if there’s any response

  • Make sure the battery isn’t dead

If none of the above helped and your mouse is still not showing up on the Bluetooth devices list, try the following:

  1. Go to System Preferences ➙ Bluetooth ➙ check that Bluetooth is on

  2. Plug in your mouse with the Lightning cable

  3. Go to System Preferences ➙ Mouse ➙ Set Up Bluetooth Mouse ➙ wait for your Mac to search for the device and connect to it

How to easily wake Bluetooth connection up?

Bluetooth not working on Mac doesn’t happen that often, but when it does it can get quite frustrating. No need for despair — sometimes devices disconnect simply because they haven’t been used for a while. Just make sure to take the following checklist into account before looking into any further Mac Bluetooth troubleshooting:

  • Check the battery. If the battery is low, the device will have difficulty connecting. The Bluetooth icon in the menu bar will warn you too.

  • Make sure you turn on Bluetooth on Mac. Simple but often overlooked step.

  • Bring the device within 30 ft from your Mac and avoid any interference from household devices (cordless phones, baby monitors, microwaves, and wireless networks that use the same 2.4 GHz band) and metal objects.

If nothing helps, try these tips below to reset Bluetooth on Mac.

Tip 1: Turn Bluetooth off and back on

Restarting can sometimes fix the problem. Simply click on the Bluetooth icon in the menu bar at the top of your screen, choose Turn Bluetooth Off and then Turn Bluetooth On. 

Tip 2: Disconnect all USB devices

If turning your Mac Bluetooth off and on didn’t help, try disconnecting all your USB and Bluetooth devices and then connecting them back on again:

  1. Go to System Preferences ➙ Bluetooth

  2. Click on X beside the device to disconnect it

  3. Restart your Mac

  4. Wait for a few minutes and reconnect your devices

Note that there can be too many connected Bluetooth devices. The maximum number is seven, but at times you might encounter problems once you go over three or four, as some devices need more data than others.

Tip 3: Delete the Bluetooth .plist files

If you still have Mac Bluetooth not available, try deleting Property List files. They sometimes could become corrupted and stealthily affect Bluetooth connectivity. To remove the .plist files:

  1. Choose Go from the Finder menu at the top of your screen ➙ Go to Folder

  2. Type in: /Library/Preferences ➙ Go

  3. Find the com.apple.Bluetooth.plist file and delete it

  4. Go back to Go in the Finder Menu ➙ Go to Folder

  5. Type in: ~/Library/Preferences/ByHost ➙ Go

  6. Find com.apple.Bluetooth.xxx.plist file and delete it 

Now shut down your Mac and keep it turned off for about a minute. After the restart, it will automatically generate new .plist files, which should fix the issue of MacBook Bluetooth not available.

Tip 4: Reset the Bluetooth module

If none of the above troubleshooting solved the problem of Bluetooth not available on Mac, resetting the Bluetooth module will attempt to debug any issues on a deeper level. Here’s how to reset Bluetooth on Mac:

  1. Hold Shift + Option and click on the Bluetooth icon in the menu bar

  2. Click Debug and select “Remove all devices”

  3. Click Debug again and select “Reset the Bluetooth module”

  4. Restart your Mac and re-pair your Bluetooth devices

Tip 5: Optimize and remove your system junk
