Hi,
I made some small progress... I am currently mining on a MacBook Pro running OS X 10.7.5.
But... only using Win XP running in a Parallels 7 environment.
There I installed the 3.0.2 bfgminer (32 bit version) and the CP210x drivers:

Next step for tomorrow: Copy the VM to the Mac Mini and try it with all 4 USB ASICs and the Ztex
Boards (running natively on OS X).
