Help!

[Ok guys this is my first post here so please be kind to a total newb looking to get this up and running!
I've been using emulators for years now and have experience in all the popular ones such as MAME, Model 2, Daphne and suchlike, in fact I have a half cabinet set up at home for all my emulator purposes!
Recently though I've made the switch and bought an all singing, all dancing iMac which I'm just about getting to grips with.
I've managed to get the model 3 emulator sort of up and running but unfortunately I keep running into the same fault as most people running Mavericks where the roms crash after a few seconds of running, after studying various posts on here I'm lead to believe that the emulator needs to be recompiled with a couple of lines of code changed to function properly, unfortunately I'm so new to Macs that I don't have the first clue where to start, I'm certainly no coder and have absolutely no experience of Xcode or any of the other tools mentioned but I am willing to learn if it means getting Daytona 2 and Starwars Trilogy up and running!
My question to you guys is can anyone explain in laymans terms how to go about starting, are there any guides available that explain in a simple way what would be required of me and also do you guys think it would be easy enough for someone with absolutely no experience of mac operating systems to fathom? Nearly every emulator I've ever used has come with an easy to use front end so even using the terminal to run it is new territory for me!
Thanks for reading and I really hope one of you guys can help me out as I'm desperate to put my new toy through its paces in the emulator world!
Thanks in advance!
