I have a sound problem on my 2010 Mac mini. I found a solution that uses a sudo command in the Terminal app. But this method only works one time, so when the computer turns off and then back on, you need to start over..

Please bear with me - I'm new in this Mac universe.

From this site, I’ve found that you can use a Launch Daemon to execute it.

I can't seem to figure out a working file.

My sudo command for the sound fix is:

sudo kextunload /System/Library/Extensions/AppleHDA.kext

After that type:

sudo kextload /System/Library/Extensions/AppleHDA.kext

Remember, sudo requires an administrator password.

My idea here is to run this at startup so I don't have to type it every time.

Can someone help me write it?

  • A few things..it’s not a “sudo command”. sudo allows you to run any command as another user, in this case root. Since you mention running as a launch daemon, then those commands are already run as root, so sudo isn’t necessary. There are existing posts on how to do this – Allan Mar 03 '20 at 20:13
  • You just need to have the service run as root. This should have everything you need to know. – Harv Mar 03 '20 at 20:15

    I understand that you’re new to Mac’s, but unloading and reloading a driver (that’s what kexts are), especially on start up is way outside the norm for any computer. It’s better to address the underlying issue rather than budge together a “fix” that doesn’t really solve a problem – Allan Mar 03 '20 at 20:19
