The graphic card you have in your mac (intel GMA 950) is a well known trouble maker with openGL… we actually cannot do anything to change this, it's a problem from this crappy cards and it's the same on mac/pc/unix… It's not even a driver problem. You'll get graphical errors on the output/preview and interface of modul8 with this crap…
Sorry about that, but the only advice I can give you is to change your computer if your budget allows that… It seems that apple changed its strategy as the macbook has NVIDIA again now.
For your groupA/B "problem", you only selected what you want to see in the preview window. If you want to output either group A or B, you have to check the fade checkboxes located in between the two layer groups, then you have a cross fader that allows to do what you were looking for.
