If your Bluetooth-enabled device is unresponsive and you've already replaced its batteries, you may need to uninstall and reinstall the device to your Macintosh computer. By removing the device's pairing from the Bluetooth settings in the Macintosh's System Preferences, you clear errors that may have occurred while it was paired to your computer. However, removing the device from the list of Bluetooth-paired devices also removes previous configuration settings, so you'll have to add those back to the device.
