Fix Bluetooth Devices Keep Disconnecting From Mac With These 8 Steps

Bluetooth is a widely used feature. It's a very useful tool, and when it stops working correctly, it's not fun. If your Bluetooth devices keep randomly disconnecting from Mac, there could be a few reasons for this problem. It can either be problems with Bluetooth, your Mac's software, the device, or a few connected devices, a minor error in the Bluetooth files, and hardware issues.

What To Do When Your Bluetooth Devices Keep Disconnecting on Mac?

If an issue is with software, you can either restart your device or update the software. If a problem lies with the connected device, you need to check if it's damaged. You can also try to connect to another mac and check if it works with another device. If it works with another Mac, the problem is probably with your Mac.

If the reason for Bluetooth not working is a corrupted Bluetooth file or a small error, try to delete its PLIST files and reset the Bluetooth module. If a connected Bluetooth device is almost out of battery, you need to charge it. Otherwise, it will keep disconnecting.
