41CL and Mac Mojave - USB-to-serial device no longer in /dev

[smp]

Thanks very much, Sylvain, for your response.

I do not need drivers. Mac Mojave has built-in support for my Prolific device. My problem is, even though I can plug my USB-to-serial device in, and my computer will work with it just fine, it does not show up in the /dev list, so I cannot direct the 41CL update where to go.

It used to be that in the /dev list I would see tty.usbserial after I plugged in my device. This no longer happens in Mac Mojave 10.14.2. When I use /dev/tty.usbserial in my Java command for the update, it responds with an error message that it couldn't open the serial port.

My other Mac applications find the USB-to-serial device automatically, without me having to direct them to it. But the Java Update application needs some direction in the command line.

Thanks for trying... Looks like Mac Mojave has done me in.
