Q: macOS Sierra - No Sound

I just updated to macOS Sierra. Now I have no sound what-so-ever.

 

Checked all the usual things (speakers, volume, settings, etc.).

 

Is there a macOS 10.12 sound driver or anything that I can reinstall?

Mac mini, iOS 10, null

    You can always try a restart of the computer, to sort various glitches.

    Yep, tried that, as well as running Disk Utility. Still no love.

    Thanks Kappy, I will give that a try.

     

    I have booted into a 10.11 backup and the sound is working, so that confirms that it's a 10.12 issue and not speakers or anything else.

     

    Re-installing now...

    System Preferences > Sound

    Check to see if Mute is checked.

    Thanks guys. When I booted back into 10.12 from the 10.11 backup, the sound mysteriously came back.

     

    Appreciate everyone trying to help

    I find that sound is often muted for me. Even in Apple Mail, I have to first select to play a sound in a rule, THEN the sounds works. Somethings strange in the neighborhood....

    Went to boot up this morning and the sound was gone again.

     

    I will follow the instructions as outlined by Kappy and update post if anything happens.

    Holding down the Command and R keys is doing nothing. Tried with two different keyboards (bluetooth and usb).

     

    Any other way to do this?

    Went to this page;

     

    About OS X Recovery - Apple Support

     

    Was able to log into internet recovery. Used Disk Utility (older version) and when done selected reinstall OS X.

     

    It wanted to install a much older version of OS X (10.7 Lion) so I booted out.

     

    Using SuperDuper backup of 10.11 to reinstall 10.11. I will upgrade to 10.12 from there.

     

    Looks like this will be an all day job...

    The Disk Utility on Recovery should have been the new Disk Utility not the old one. This indicates to me that you had a bad update. The next upgrade should fix your problem.

     

    Note: you can run the macOS Install OS X Sierra again if needed. Make sure you copy the installer in Applications before you run the installer. Apple deletes the file automatically after running.

    Do you happen to know what it's called? I couldn't find anything in Applications regarding Sierra...

    OK Thanks. Nothing in Applications like that so it must have been already deleted, or never put there.

     

    Guess I'll copy 10.11 from SuperDuper and then update to 10.12 from there.
