Hi all,

I am a little out of my depth with my Chirp connection to my Yaesu FT7800
on my MacBook (OS 10.14)....('had no issues earlier with a Win 7 machine
and this cable).

Chirp is returning "could not open port /dev/cu.monic-SerialPortService:
[Errno 16] Resource busy: '/dev/cu.monic-SerialPortService'"

Mac OS Sys info returns:

*USB-Serial Controller:*


  Product ID: 0x2303

  Vendor ID: 0x067b  (Prolific Technology, Inc.)

  Version: 3.00

  Speed: Up to 12 Mb/sec

  Manufacturer: Prolific Technology Inc.

  Location ID: 0x14200000 / 7

  Current Available (mA): 500

  Current Required (mA): 100
  Extra Operating Current (mA): 0

Hopefully a Mac expert can point me in the right direction to debug??

Thanks in anticipation and thanks for considering my issue!

73,

Brendon (VK4MHZ)
