A few weeks ago, the sound on my Mac just died. Nothing was coming from the internal speakers, the headsets, or external systems. When I get into the sound icon from system preferences, I'm told that there are no input or output devices available. Everything but the sound works fine, except if there's an interview in a story, music, or any audio, I get dead silence.

Is this a fatal breakdown or can it be fixed for under the $2300 I paid for it originally?

I didn't expect it to help, but I tried to restore everything with the Time Machine--no luck there.


  • What if you plug something in the headphone jack - does that work?

  • Could you connect bluetooth audio as an alternative? If you need a motherboard fix it's way expensive normally ...

  • You might be able to get someone to open it up and check for loose connections for a couple of hundred.

Did you try to run the Mac in Safe Mode? Were the results the same?

What about setting up a new user profile (make sure its an admin)? Is the sound still not working with the new user?

If safe mode and a new user are not showing any results that are different from what you currently experience then do the following:

Option-Command-P-R: Reset NVRAM or PRAM. If your Mac is using a firmware password, it ignores this key combination or starts up from macOS Recovery.

The last resort should be to contact Apple Support for any further testing and then they can determine if repair is necessary. Before calling Apple Support, make sure you have an external hard drive (only for your Mac) and back it up so that you can secure your contents and files safely before repairs are done.
