The transmitter is in the mic itself, the receiver is what you want to connect to the Mac. I can’t see the rear panel of the receiver but it probably has an XLR output connector on it. You will need to connect this to whatever your Mac has, which might be a mini jack or you can also get a USB converter too.
So you will need a cable and/or jack that takes an XLR connector on the receiver end and ends up with a mini plug or USB connector on the other.
