If the mixer has audio line-out, and your MacBookPro has an audio line-in you can record the output of the mixer in Garageband. Your mixer has two outputs - 1) 2x RCA and 2) 2x 1/4' TRS. You will need a cable with one pair of connectors matching the mixer output you want to use, and on the other end a single 3/8' (aka 2.5mm) male stereo plug to connect to your MacBookPro.
Taylor Martin/CNET By default, there are several menu bar applications preloaded on the Mac, most of them giving you quick access to the most commonly tweaked settings, such as volume, Wi-Fi. Application specific volume control app for Maclink: http://www.volumemixer-app.com/.
In GarageBand you will record from the audio input. There is no 'connection' between the mixer and GarageBand per se.
Note: You didn't say what model MacBookPro you have. In the current lineup, only the 15' MacBookPro still has audio line-in. Check yours to make sure it has an audio-in port.
