Do you mean separate mic input? Because it has the same combo headphone jack as all existing Macs. So it has mic input.

As a pro audio user, a built-in mic input is useless anyway. We have external USB3, TB, or Firewire interfaces for that. Lower noise, better DACs, phantom power, HiZ and XLR inputs, etc.

Beyond pro, nobody uses mic input unless they are using an iPhone headset on their Mac. Everyone is using USB mikes/headsets.
