How to Reset Bluetooth on a Mac

Bluetooth, often known as “personal area networks”, is a handy tool for short-distance communications. Maybe you use Bluetooth devices every day without even noticing it.
Whether you need to connect a Bluetooth headset, pair a Bluetooth keyboard, uninstall a paired Bluetooth accessory, or pair a Bluetooth speaker, you may encounter all kinds of Bluetooth problems.

Advance Checks

If you haven’t tried any troubleshooting for the problem device, we recommend that you read the following suggestions carefully before resetting Bluetooth on your Mac.
Check compatibility: If a Bluetooth device fails to link with your Mac, you should eliminate the possibility of compatibility issues. It is possible that the device requires a newer version of macOS or does not support the Mac at all, such as Apple Watch. For details on device compatibility, refer to the device’s package or the manufacturer’s website.
Close the device: Bluetooth can reach 30 feet, but don’t think it will always succeed. If the device can’t be paired or it disconnects, move it closer to the Mac.
Prevent Bluetooth interference: Bluetooth interference may be a factor too. Before trying to pair the device with a Mac or using the device again, try to leave an area that is known to cause interference.

In some cases, applications will interfere with the operation of Bluetooth. Clearing the cache can help solve this problem. To avoid any complications, you should first clear the Mac’s cache file before restarting the Bluetooth. If it looks too complicated, don’t worry — try our handy tool, Cleaner One Pro, which can scan your mac quickly and solve multiple problems.

But sometimes, even these suggestions won’t help. If you find yourself in this situation, you’ll need to reset the default settings on the Bluetooth module of your Mac.

Restart your Mac.

After resetting your Mac’s Bluetooth in System Preferences, the Bluetooth module on your Mac will be reset and returned to factory settings, so you’ll need to reconnect all wireless devices. If your Bluetooth devices are turned on, can be found on your Mac, and are in range, you should see them listed there. To connect a device to a Mac, select the device, and then follow the on-screen instructions.

If the Bluetooth problem still exists, you can contact Apple Support, or make an appointment at the Genius Bar nearby.
