Salivations!
I've been working on my MAC with Arduino for nearly a year without issue. I got a couple XBEE boards and installed x-ctu (version 6.1) and started having troubles.
x-ctu could not recognize my xbee boards until I installed the FTDI USB Serial Drivers. But now, I can't communicate with my Arduino. I'll click the Upload button, I will see the LEDs flash as usual, but the upload fails with the message avrdude: stk500_recv(): programmer is not responding on one Arduino, or avrdude: stk500_getsync(): not in sync: resp=0x00.
I've searched and tried different solutions, plugging and unplugging, insuring no shorts, correct chip placement, different ports, correct board, restarting... Also installed latest Arduino dev environ (1.0.5).
This has to have occurred because of the x-ctu and FTDI driver install, just not sure how to fix it.
Appreciate the help.
