Arduino Install fails on MacOS 10.7.5
The Arduino UNO is not functional and in fact when you have 10.7.5 an error such as: “Serial Port Already in Use” /dev/tty-ZCASDFASF in my case: /dev/tty-EdwinHernandez-1 is already in use may prompt. However, this is not what is going on. The USB on the Arduino from OSEPP UNO R3 PLUS is not listed in the VID/PID of the FTDI Driver
