[Ham-Mac] OS X Yosemite

[Chris Smolinski]

A note that Yosemite, like 10.9, has the FTDI usb/serial driver built in. So you should not need to do anything special if you use my USB CI-V adapter, or any other devices based on the FTDI chipset, unless the software makes use of the D2XX interface, instead of the usual virtual serial port.  Some SDRs use the FTDI chip with the D2XX interface; you may have issues in that case.
