AudioHardwareServiceHasProperty error

Hi! do you know something about this? 

the message says ¨AudioHardwareServiceHasProperty is deprecated first deprecated in osx 10.11¨


hope you can help me!

It's not an error, it's just a warning.

Like it says, that function has just been deprecated by Apple in their latest SDK. It'll carry on working for at least a few years though, no need to panic! We'll replace it with an alternative at some point soon to avoid the warning.
