In my opinion, this is not possible!
The jack plug cables work for photo cameras with MIK input with TRS plug (2 rings). For smartphones (e.g. iPhone) you need a TRRS plug (3 rings) - as this input is a headphone and mic input.
If the MacBook had a "3.5mm jack mic input", it would work. But it probably doesn't have one? That's why usually only a USB microphone works with Compis.
But maybe someone else knows more? (-:
