You have some great Producer Software on your Mac, every Mac comes with GarageBand, I’ve had a Mac for years and have never really used Garage Band for much. I have developed a few voice-overs for a few projects, but that was about it.
What I have found out after watching this Tutorial is that you have a powerful production tool for making Demos for any kind of music, just using your acoustic guitar and singing.
You can learn a lot right from this one tutorial. Listen to this guy as he takes you from the basics to mapping out your whole song than recording, it will take you a little bit of time, but you should have a demo sketched out within a few hours after watching this demo, it’s actually kind of funny too.

I have added a Focusrite external device for my microphone and bought at B-2 Microphone and Headphone Kit from Behringer, and now have a decent sound and monitoring for making my demos.
