Description

Mac Computer running 10.11.6, I downloaded the newest version 11/28/20 Chirp, when radio plugged in and I try and download from radio I only have two options for serial port, I am using a baofeng cable and never had problems until I upgraded my system software. I have attached a screen shot of the options for serial ports. Not sure where to go from here.

I'm going to guess that you don't have a compatible driver installed for the USB-to_Serial chip in your programming cable installed. Most Baofeng labeled programming cables have an unauthorized copy of the Prolific PL-2303 chip. The latest macOS driver provided by the chip vendor is incompatible with unauthorized copies of their chips. More recently these programming cables have began shipping with the WCH CH340 USB-to-Serial chip.

I'm really not well versed at using an Apple mac computer. I had a MacBook Air given to me and pretty much all I have ever used it for was testing CHIRP. I use google search to figure out what commands I need to use to get something done.

What I did to workaround the Prolific driver/chip issue was to purchase a 3rd party driver for the PL-2303 chip. It works great for all of my many programming cables with "fake" Prolific chips.

I have also attached the notes I created for determining which chip is in a programming cable using my MacBook Air. I went through my more than 20 programming cables and use my MacBook air to identify the chip in each programming cable and label it accordingly. The notes include links to each chip vendors driver download area. There is also a link for the 3rd party driver vendor that provides the Prolific compatible driver that I purchased ($9.11) and use.
