<div dir="ltr">Here is what I found. The driver is the issue with Yosemite. The built-in FTDI driver prevents the osx-pl2303 driver from loading.

The driver that works for me is the Lion driver from <a href="http://miklor.com">miklor.com</a>.</div><div><br></div><div><br></div><div>Then manually load the driver (first time only, it will load automatically after that) with this command in Terminal:</div><div><br></div><div><pre style="border:0px;font-family:'Courier 10 Pitch',Courier,monospace;font-size:13px;margin-top:0px;margin-bottom:1.625em;outline:0px;padding:0.75em 1.625em;vertical-align:baseline;font-stretch:normal;line-height:1.5;color:rgb(51,51,51);background:rgb(244,244,244)">sudo kextload /System/Library/Extensions/osx-pl2303.kext</pre></div><div>This creates the device cu.PL2303-000012FD, be sure that is what you select in the CHIRP Radio dialog in the Port drop-down.

it should run with no issues. I use Chirp on a mac but not 10.10. I<br>
think I'm at 10.9. If you are still having trouble I'll upgrde and see<br>
if we can work through it as others will undoubtely have the similar<br>
