              Anyone out there using this programmer with a Mac? Need a response to this problem:
I bought this programmer because it said it was OS X compatible. When
I plug it in, I don’t see a serial port in /dev/. System Profiler
does see the device though.
Is there a driver I need to install? Something else?
Use this thread to discuss this issue.
             
            
              
            
           
          
            
            
              I don’t have the exact model you have, and i don’t use mac osx, i use linux, but i still might be able to help.
this is the one i use, and i think it is basically a clone of yours.

“he USBtinyISP doesn’t act as a serial port, and thus won’t show up in /dev. You’ll need to use avrdude to access it through the libusb library (which, I admit, might be an overly technical way to describe it).”
