I'm trying to record on my Mac book pro early 2015, but the Line-In port does not appear. I only have the "built in Mic" option. I have plugged different kinds of mini jack in the only in/out port, with the device already turned on...and NADA.

You don't have a line in.

Per the Technical Specifications for your MacBook, it has support for a line out, but not line in.


  • Stereo speakers
  • Dual microphones
  • 3.5 mm headphone jack
    • Support for Apple iPhone headset with remote and microphone
    • Support for audio line out (digital/analog)

Emphasis mine

To get a Line-In, I suggest using a USB-DAC or a USB Mixer so you can get a proper line level input and output. In fact, I try not to use any of the built in audio ports due to their poor shielding and "economy grade" components. You'll get better results with a proper audio interface.

    Thank you so so much. I switched from a Mac 2012 to this and the previous one had it. Crazy- I will buy an external usb adaptor or a Focusrite audio

  • @allan Wouldn't plugging in a 3.5mm headphone with a built in microphone, act as the line in though? Or are you saying the sound input is inferior to using a USB-DAC/Mixer? I thought all TRRS headphones (3 rings on the headphone jack) would produce the same input quality? I know Macs are compatible with the TRRS standard so it should act as both output and input.
