When I first put Yosemite on my late 2011 Macbook Pro, CHIRP continued to run fine to program my Baofeng UV-5R. Then for no apparent reason, since I didn't change anything, all I could get was "The radio did not respond." I am using the latest daily build of CHIRP. So then I went to the net to research Yosemite and drivers and found the Terminal command to allow unsigned drivers to load and the command to load the kext for the driver that had been working. This appeared to work for a while, I was able to download from radio and upload to radio, and I thought all was hunky dory. Then in a day or so, once again it stopped working. Nothing I try works, I have tried all the various drivers on miklor.com, although they don't even mention Yosemite, they stop at Mavericks.

I have a programming cable from cheapham.com, which I assume is a generic chipset, since it cost all of $8. This cable works reliably on my 2006 white Macbook and my 2006 iMac, both running Snow Leopard, so I can program my Baofeng with CHIRO, but I sure would like to be able to use my Macbook Pro. Is a new more expensive "genuine" FTDI programming cable going to fix the problem on Yosemite? Which one from which vendor?

Thanks!
