Sims 4 Studio Tutorial For Mac?

Is there a tutorial for Sims 4 Studio for Mac anywhere? None of the online instructions I've seen so far look anything like my program. I've successsfully recolored a Maxis mesh, but I can't do anything more complicated like removing the reflections from buttons. Thanks for your help!

Edit: Looks like I've solved the button-reflection issue. Making the specular blank seems to have eliminated the button reflections without allowing regular Maxis bottoms to show through. A tutorial would still be great though!
