update 3:    This also works when the mount is connected to the Mac by USB
cable. But you have to download and install a driver.

Connecting the handset to the computer and looking in the USB section of the
System Information “app” you can find that there is a USB-Serial controller
attached made by vendor Prolific Technology, Inc with device ID: 0x23a3. After
looking for references listed on the internet for this device, I came across a
posting that said the Prolific company had device drivers listed on the Mac App
Store. This is true, they do have at least two drivers there. Taking a wild
guess the 0x23a3 device used the 2303 device drives, I installed it (when you
download it from the App Store, it is installed, you then have to immediately
go to the Privacy & Security tab in the System Settings app and give the driver
permission to run. Do that and just to be sure, restart the computer, With the
handset attached to the computer via the USB cable, start KStars and EKOS and
go to the Indi Control Panel and select the iOptron HEM15 tab. You will need to
change the Connection Mode to Serial, select System Ports, and for the Ports
select the newly installed driver for the handset. Mine is
currently.cu.PL20303G-USBtoUART1430, baud rate is 115200. Maybe restart Stars
and EKOS just to make sure everything sticks. One thing to note: if you open
the Terminal app and type 'ls /dev/tty*.*'without the quote marks and press the
return key, you will get a listing of all the USB connected devices, so if the
driver name changes after this posting, you can still find out what it is.
