Restart and Reset Processes
Restarting and resetting processes can often resolve Bluetooth connection issues on your Mac. Follow these steps to troubleshoot and fix the problem:
1. Restart your Mac: Sometimes a simple restart can resolve connectivity issues. Click on the Apple menu in the top-left corner of your screen and select “Restart.”
2. Reset the Bluetooth module: This can help refresh the connection. Go to System Preferences and click on “Bluetooth.” Press and hold the Shift + Option keys together, then click on the Bluetooth icon in the menu bar. From the dropdown menu, select “Reset the Bluetooth module.”
3. Remove and re-pair devices: If you’re having trouble connecting a specific device, remove it from your Mac’s Bluetooth settings.
