system_profiler SPBluetoothDataType
Again, look for recognizable devices and their connection statuses.
Troubleshooting Common Bluetooth Issues
Restarting Bluetooth is often the first step in troubleshooting connectivity issues. However, if problems persist, consider these additional troubleshooting steps:
1. Ensure Bluetooth Is Turned On
Navigate to the Bluetooth section in System Preferences to ensure that Bluetooth is enabled. If the Bluetooth toggle is off, turn it on and attempt to pair your device again.
2. Remove Known Devices
Sometimes, issues occur if your Mac attempts to reconnect to a device that is no longer available. Remove old devices by going to System Preferences > Bluetooth, selecting the device, and choosing to remove it.
3. Reset the Bluetooth Module
Resetting the Bluetooth module can also resolve persistent connectivity issues. Hold down Shift + Option and click on the Bluetooth icon in the menu bar. You will see a “Reset the Bluetooth module” option; select it to execute the reset.
4. Check for Interference
Bluetooth operates on the 2.4 GHz frequency band, which can often be crowded with signals from Wi-Fi networks, microwaves, and other devices. Ensure that your Mac is away from potential sources of interference, and consider changing your Wi-Fi router to operate on the 5 GHz band if applicable.
