Given the challenges many MacOS El Capitan folks have associated with getting CHIRP to program their handheld transceivers and scanner because of the requirements for Apple signed drivers and for "real" 2303 USB to serial cables, I thought I would post a configuration that I have working successfully.
Environment: MacOS X 10.11.5 on 2012 Macbook Pro retina
Transceiver: Yaesu VX-3R
Cable: Farmunion Usb Programming Cable for Yaesu Vertex Vx-3r, https://www.amazon.com/gp/product/B00XL3EYB4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Driver: mac-usb-serial.com, PL-2303 Driver (V2.5.1) for El Capitan; yes, it costs Euro7.47, but it seems to be worth it; I wasn't able to make any other driver work.
Chirp version: MacOS X chirp-daily-20160625.app
1. You should be sure to remove conflicting PL-2303 drivers from Prolific or Winchiphead before installing the mac-usb-serial.com version. Then run the PL-2303 Driver installer you got from mac-usb-serial.com.
2. Once you've installed the driver and connected up the USB cable to the radio mic/headphone port on the top, you have to place the VX-3R into "Clone" mode by holding down the F/R key while pressing the Power button. The radio should read "Clone"
3. Launch Chirp. You'll get a blank screen.
4. Select "Download from Radio" from the "Radio Menu"
5. You should now see a port listed that looks something like /dev/cu.Repleo-PL2303-0000xxxx. Select that from the Port pulldown. Also select Yaesu as your Vendor and VX-3 as your model. Hit OK.
6. Now go to your radio and hit the "Band" button. You should now see the Radio say -- TX --.
7. After about a minute, CHIRP should now show the memories on your radio. You can now edit those as you like and then upload them back to the radio.
8. To upload your modified memories to the radio, select "Upload to Radio" from the Radio menu in CHIRP. Do not hit OK yet.
9. Your VX-3R should still be in Clone mode. If it isn't, turn it off and restart it by holding down F/R and hitting the Power button.
10. Hit the VX-3R V/M button, and the Radio should now say "-- RX --" on its display.
11. Hit the OK button on the Radio dialog box you pulled up in Step 8. CHIRP should now show progress in cloning to the radio.
12. Your radio should now be programmed.
One final thing. Should you want to pull frequency lists into CHIRP from RadioReference.com, you have to do a couple more things:
1. Get a Premium subscription to RadioReference.com; Web interface frequency lists are only available to premium subscribers.
2. Install the SUDS library onto your Mac using the following command:
sudo easy_install -z suds
3. Restart CHIRP.
You should now be able to either Query or Import frequency lists from RadioReference.com
I hope this saves someone else the day or two I spent figuring out this combination.
