    Can anyone post the output from the "Audio" section in the System Report? I am curious to know the differences between the audio processor in the new MacBook versus that in the MacBook Pro.

    Thank you!

    Everything appears to be identical with the MBP except for the "Audio ID". Mine (15", Mid-2014, dGPU) says 94.

    Does anyone know what the Audio ID refers to?

    No idea, but they just seem to be using Intel's standard audio chip. So, I don't expect many differences.

    I think the MacBook only I/Os at 16-bit, which is quite a big difference.

    The MBP switches up to 24-bit and 32-bit float. Could someone check in Audio MIDI Setup..?

    Can confirm that the MBP does 24-bit integer and 32-bit float at (up to) 96 kHz. Have no idea about the MacBook.

    Sorry, yeah, I know. I meant could someone check Audio MIDI Setup on their MB. :)

    I don't see anything higher than 16-bit in the built-in audio output options, but I don't have an external device to connect it to.

    Checked one out in store and the output is 16-bit while the mic input is 24-bit. It makes sense to have higher dynamic range on the input if you have to go for one of the other, but both would have been preferable, of course, particularly given that the built-in mic is for Face Time and Skype, not recording vocals!

    Ah well.
