Thanks for the tip. I actually have a keyspan serial port on my system.  I’ll see If I can find a 9 pin everything else cable.  But I mostly use a prolific device too, only because has a Kenwood style plug. 
Whats really odd is that I dont any issues with any other radios other than the KG-UV8* series, chirp won’t get stuck.  No issues with all the Baofeng, Btech, Yaesu’s  Windows VM running under MacOs as can use the Wouxun KG-UV8* driver is fine too.  Thats why Im kinda not thinking its entirely a serial driver issue, but more an interaction with that chirp code than anything.  I might still be wrong

I dont know if you’ve read my long winded email a couple weeks back regarding how the macOs version locks up the serial device hard while using the new Wouxon KG-8* drivers.  This can only be duplicated when chirp is running under macOS. So Im under the impression that it has something to do with the runtime.

There is absolutely nothing that something in userland (an application) should be able to do to lock up a piece of hardware, especially something so simple as serial communication. There is nothing in the runtime relating to low-level serial communication. The reason that it doesn't happen on other OSes is because their drivers are better. This is the reason I've pretty much stopped using MacOS for any of my serial activities (CHIRP or otherwise).

However, most everything I get nowadays has a USB converter in the cable shell. If I were to cut that off and rewire them all (which you could do) then I'd be able to continue, but that's just totally not worth it.
