I will do my best to test it on 10.8.2 sometime today or tomorrow as I need to fix my wife's VX-7R with correct power levels since they are totally messed up from a bug.
Okay, tested with both my wife's Yaesu VX-7R with a counterfit prolific USB cable from KaWaMall, and my own Wouxun KG-UV3d with a counterfit Prolific Chip USB cable from some other reseller on eBay. Both work great with the driver above with MacOSX 10.8.2 on my June 2012 MacBook Air 11".
I downloaded it again and followed the installation steps. I used "sudo" at the start of every line/step they outline on that webpage, even though it didn't say to, better safe than sorry. The port shows up for me as: /dev/cu.PL2303-00002014.
Good luck, hope that works for you.
