Bluetooth gives you the freedom to use devices such as keyboards and headphones wirelessly, but it is not always reliable. If you encounter problems with Bluetooth in macOS, you can follow these steps to resolve them.
Initial Basic Steps
Before you go to the Apple Store or start thinking about replacements, follow some of these more general troubleshooting steps first. Often the basic steps can solve a Bluetooth connection problem.
Check the pairing status
A good first step is to ensure that your device is paired and properly connected to your Mac. Go to the Bluetooth settings menu to check this. Click on the Launchpad icon in the Dock and then click on System Preferences> Bluetooth.

Reconnect with your Bluetooth device
If your device is not connected to your Mac , switch your Bluetooth device off and then on again to see if it reconnects. This is also a good time to check the battery level on your device. If it has insufficient capacity to function, take the necessary steps to resolve this.
If your device has sufficient power but does not reconnect automatically, click the Launchpad icon in the Dock. From there, go to System Preferences> Bluetooth and then click "Connect" next to your device.
If you see the Bluetooth icon in your menu bar, you can also use it to connect (or reconnect) your Bluetooth device.
To display the Bluetooth icon in the menu bar, select the check box next to "Show Bluetooth in menu bar" in the Bluetooth Settings menu.
Each paired device has an entry in the Bluetooth menu on the menu bar. To disconnect your device, move the mouse pointer over the name and click & # 39; Disconnect & # 39 ;. Click "Connect" to reconnect.
Restart your Bluetooth radio
If your device does not reconnect, you can restart the Bluetooth radio on your Mac. To do this, click on the Launchpad icon in the Dock and go to System Preferences> Bluetooth.
Then click on "Turn off Bluetooth" and then on "Turn on Bluetooth".
If it is switched on, you can also do this via the Bluetooth settings menu on the menu bar. Click the Bluetooth icon, click "Turn off Bluetooth", and then click "Turn on Bluetooth" to restart it.
Remove your Bluetooth device  If none of the previous steps works, you can try to remove the troublesome Bluetooth device completely from your Mac before considering more intrusive steps.
To do this, click on the Launchpad icon in the Dock and go to System Preferences> Bluetooth. Right click on your device and then click on "Delete".
After the device is removed, you can try to pair it again. However, first make sure that the device is configured correctly. For example, you may need to set up a Bluetooth keyboard for the correct keys to work.

Restoring factory settings All connected Apple devices  Apple hardware usually works best with other Apple devices, but that doesn't mean that accessories such as Airpods always work perfectly with macOS.
It may seem drastic, but you may consider resetting your Airpods or other Apple peripherals if you cannot restore or stabilize Bluetooth connectivity. This may be harder to do with an iPhone, but it is a simple process for smaller devices (such as Airpods).

Instead of performing this action for each device, you can do it on all connected Apple devices in the Bluetooth debug menu.
The Bluetooth icon must be visible in the menu bar to do this, so we start there.
Switch the Bluetooth icon in the menu bar
If you do not see the Bluetooth icon in the menu bar, click the Launchpad icon in the Dock and navigate to System Preferences> Bluetooth.
Click the check box next to "Show Bluetooth in menu bar" to enable it.
Enter Bluetooth Debug Menu and Factory Reset Apple Devices
When the Bluetooth icon is visible in the menu bar, press and hold Shift + Option and press click on the Bluetooth icon. The Bluetooth menu appears and contains an additional "Debug" menu and other hidden connection information.
Click on "Debug" and then on "Factory Reset All Connected Apple Devices". This only works if your Bluetooth device is currently connected to your Mac; If this is not the case, follow the reset instructions for that device instead.
Accept the warning and click "OK" to start resetting all connected Apple devices.
Once the factory reset process has been completed on all your devices, you must pair and reconnect them in the Bluetooth settings menu, either from the System Preferences menu or the menu bar.
Remove all Bluetooth devices or reset the Bluetooth module
From the Debug options you can also remove all Bluetooth devices from the Bluetooth configuration or fully reset the macOS Bluetooth module.
Again, to do this, the Bluetooth icon must be visible on the menu bar. If this is not the case, click the Launchpad icon in the Dock and navigate to System Preferences> Bluetooth. From there, click the check box next to "Show Bluetooth in menu bar" and the icon should appear.
Press Shift + Option and click the now visible Bluetooth icon to open the Debug menu.
Delete all Bluetooth devices
In the Debug menu, click "Delete all devices" to delete all Bluetooth devices stored in the macOS Bluetooth configuration.
Click on "Delete" to confirm the action.
Reset the Bluetooth module
You can also completely reset the Bluetooth module from the Debug menu. This will clear the Bluetooth configuration, reset the Bluetooth hardware, and disconnect all connected Bluetooth devices.
Click on "Reset the Bluetooth module" to start.
Click on "OK" to confirm.
After the process is complete, restart your Mac and reconnect your devices. If you use a Bluetooth keyboard or mouse, you must reconnect it before restarting your Mac.
Check the system log
The above steps will help you solve common problems. However, if you continue to experience problems, you can consult the system log for more information.

It can help you limit potential conflicts or problems with your Bluetooth hardware or devices. Use Spotlight to access the log.
Press Command + Space, type "Console" in the text box, and then press Enter. You can also click the Search icon in the menu bar to start Spotlight. Click on the "Console" option when it appears.
Click on the "Reports" entries on the left to browse through the system log. You can also & # 39; Bluetooth & # 39; type in the search bar at the top to display relevant listings.
You cannot solve a problem directly from the system log, but it can help you diagnose a deeper problem with settings or hardware.
