How To Quickly Fix Mac Bluetooth Not Working

7 min read

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 easily fix Mac bluetooth not working problem?

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 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 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

Finally, it’s natural for your Mac hard drive to get cluttered with all kinds of user and system-generated trash over time. Bluetooth connectivity suffers too. So the next time you see MacBook Pro Bluetooth not available, try doing a thorough but quick system optimization with CleanMyMac X. 

CleanMyMac X is a powerful and easy way to bring your Mac back to its mint condition: without user or system cache files, language logs, malware, login items, and more. And it only takes one click to scan:

  • Navigate to System Junk
  • Click Scan and wait for the process to finish
  • Review Details and Clean anything you don’t need

How to fix Bluetooth problems on macOS Big Sur

If you are having Bluetooth connectivity issues on a Mac running macOS Big Sur, you have several options.

First, try the tips listed above. Next, if the problem is that you can’t turn on Bluetooth on your Mac at all, try reloading your Mac in case it just froze due to a system error or memory/processing power shortage.

For situations when Bluetooth is buggy, check your System Preferences for software updates — if your Big Sur hasn’t been updated to the latest version, chances are that a bug has been fixed with a system update, so install any suggested system updates from Apple for your macOS.

If your Macbook Bluetooth is still not finding devices, recheck if the devices are on and Bluetooth is switched on on them (if it’s not automatically on or always on). You can also reload the devices you are trying to connect to relaunch the signal. Make sure they are in range.

If you are still having issues, you might need to factory reset your device to get the system to work properly.

MacOS Monterey Bluetooth problems

If your Bluetooth doesn’t work on Mac with macOS Monterey, first and foremost, check for system updates from Apple by going to the Apple menu icon in the top left corner of your screen > System Preferences… > Software Update. Make sure your Monterey is up to date before attempting other fixes as the bug you are encountering might’ve already been fixed.

In addition to the universal solutions we’ve mentioned here, like reloading your Mac and Bluetooth devices, checking all devices have in fact Bluetooth turned on, are within range, some of the user-recommended steps to remedy the issue we found online include the traditional resets of NVRAM and SMC, and removal of .plist.

The latter we’ve covered in one of the sections above and the two former are as follows.

To reset NVRAM: shut down your Mac, turn it on, press Option + Command + P + R right away and hold for about 20 seconds.

To reset SMC: just restart for M1 Macs; for Intel-based notebooks with T2 chip, shut down, hold Control + Option + the right Shift key for 7 seconds, without releasing, press the power button and hold all the keys for 7 more seconds, release and after a few seconds turn on your Mac. More detailed instructions for T2 chip and other Macs, read Apple’s official guide here.

If you are experiencing problems connecting to a Bluetooth keyboard and/or mouse, go to System Preferences… > Bluetooth > Advanced and check these options:

As you can see, sometimes the question of how to turn Bluetooth on Mac is not as simple as clicking the respective icon in your menu bar.

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

turn on bluetooth mac

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!

  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
