Bluetooth is an integral part of our daily lives. It is reliable, however. Although it is uncommon, Bluetooth issues can sometimes occur. Many Mac users reported experiencing intermittent Bluetooth functionality problems after updating to macOS Big Sur. A few users also reported that the Bluetooth menu displayed an error message “Bluetooth Not Available”. If you try to establish a Bluetooth connection, or use a Bluetooth accessory, it is possible to encounter problems. This will make your Bluetooth accessories and devices stop working. If Bluetooth is not working properly, many macOS and iOS services (AirDrop. Handoff. Continuity. Universal Clipboard. etc.) will not function.
Bluetooth technology allows you to wirelessly attach various accessories to your Mac (keyboards, mice, trackpads, headsets, etc.) by pairing them (also known as pairing). If Bluetooth is enabled, the Mac will connect to these devices once it has been paired.
This article will explain what to do if Bluetooth stops working after Big Sur’s update.
Here’s what to do if Bluetooth stops working after Big Sur update.
The easiest way to fix Bluetooth connection issues is to unpair and set the device up completely from scratch. If your Bluetooth device continues to act up with Mac, you can follow the steps below to fix the problem.
How to fix Bluetooth issue on Mac Big Sur
Here are some solutions to Bluetooth problems after Big Sur Update.
1. REBOOT YOUR MACHINE
Let’s begin with the easiest. Rebooting your Mac is often the best way to resolve Bluetooth connectivity issues.
Navigate to the Apple menu > Restart to restart your Mac. This will resolve almost all Bluetooth problems, especially those that involve the Bluetooth module having crashed.
You might also want to unplug any USB devices and connect via Bluetooth.
2. RECONNECT BLUETOOTH DEVICE
Turn off your Bluetooth device if it isn’t connecting to your Mac. Then, turn it on again to check if it connects. It’s also a good opportunity to check the battery life of your device. You can charge it if it isn’t getting enough power.
3. RESTART BLUETOOTH ON THE MAC
You can restart your Mac’s Bluetooth radio if your device fails to connect. Click the Launchpad icon on the Dock to go to System Preferences > Bluetooth.
Click Turn Bluetooth Off and then click Turn Bluetooth on.
You can also access the Bluetooth settings menu from the menu bar. To restart Bluetooth, simply click on the Bluetooth icon and click Turn Bluetooth Off.
4. DELETE PLIST FILE FILES
MacOS stores information about Bluetooth devices on two files on your hard disk: one for you personally and one for all users. To resolve the Bluetooth not working in Big Sur, you can delete these files. Follow these steps.
Step 1: Start the Finder menu on the Mac.
Step 2: Navigate to the Menu Bar and then open Go> Go To Folder.
Step 3: Enter /Library/Preferences in the address bar.
Step 4: Find a file named ‘com.apple.Bluetooth.plist’ and drag it to the Trash.
Step 5: Click Go > Go to Folder again and type ‘~/Library/Preferences/ByHost’ in the address bar.
Step 6: Find a file that starts with com.apple.Bluetooth followed by numbers and letters (ending in .plist) and drag it to the Trash.
Step 7: Disconnect USB devices from your Mac and turn it off.
Now, turn off Bluetooth devices and restart your Mac.
5. RESTART MAC in SAFE MODE
You might be able to fix the Bluetooth problem on Big Sur by restarting your Mac in safe mode. Follow these steps.
Step 1 – Turn off your Mac.
Step 2 – Power on your Mac, and then press and hold the Shift button.
Step 3 – When the login screen appears, let go of the Shift keyboard.
Step 4 – Your Mac is now in Safe Mode. Check your Bluetooth to verify that it is working.
Step 5 – In both cases (working or not), you can restart your Mac as normal. Safe Mode will be exited by doing this. This means that you should restart your Mac, but don’t press any key.
Step 6 – Once your Mac has turned on, turn Bluetooth off again and test it again to make sure it works.
6. REMOVE SAVED BLUETOOTH DEVICES
If your problem persists after turning off your Mac and turning it on again, you can try your Bluetooth devices.
Another reason to get rid of devices is that too many devices can cause problems with connection. Although seven Bluetooth devices are the most common, there may be issues if you connect to more than three or four. Some devices require more data.
Step 1: Go to System Preferences > Bluetooth.
Step 2: Click on the x next to each device to clear out the Bluetooth device list.
Step 3: Connect the Bluetooth device again to verify that it is working.
7. UPDATE MACOS
After updating to the most recent macOS Big Sur update, I noticed Bluetooth disconnect issues with my MacBook Pro. Apple usually responds quickly to such issues with future updates. You can download the most recent patch from System Preferences and install it on your device if you’re in the same boat.
