macbook not detecting bluetooth hardware

Hello bezeeta,

We would like to see how we can help you with your Bluetooth not connecting to devices as expected. Is the Bluetooth symbol grayed out? Check out the steps in this link, though it may not be one of Apple's Magic devices, it should help with your issue: If you can't connect your Magic Keyboard, Magic Mouse, or Magic Trackpad to your Mac

Cheers!

When you click on the bluetooth icon in the top left of screen is just greyed out with nothing you can click on or does it say blue tooth not connected, found or available? Depending on the problem here are some things to try.https://www.makeuseof.com/tag/fix-bluetooth-not-available-mac/
