My bluetooth has disappeared from my macbook air - any ideas on how to reinstall or locate it?

I am NOT amused at all. I have had nothing but problems with my Macbook Pro Retina (2nd gen). NONE of the fixes stay fixed for more than a few weeks. I am ****** that Apple has hobbled my important tool making it useless to me.

Hi, I agree with you totally. One problem Apple has with its support is that they allow searching within the Apple environment and will send you to articles that are 5 6 or even 7 years old. I have tried to get them to allow OS and version and the current year to be included searches. That way it guides me to pertinent up to date help. They need to date and stamp every help article with the year also. What worked in 2013 will not work today.

Hi Lisa.lisajane.jane,

Welcome to the Support Communities!

I'm sorry to hear you are having issues with bluetooth after updating your software.

Have you restarted your computer? That is usally a good first troubleshooting step after a software update.

If you are still unable to pair your bluetooth devices to your computer, then please follow the instructions below:

You can read more details by clicking on the two links above, but these would be two good troubleshooting steps to try.

I hope this information helps ....

Have a great day!

This worked perfect! Any idea how it could have happened? I did not install a software update?
