same issue here, using Macbook pro 2021, arm-based m1 chips. Cannot install the PL2303HXD&G_Mac Driver (Mac os 10) and the mac os on the laoptop is Ventura 13.1. using parallel desktop running Windows11 and system cannot identify the NGT-1-USB device, installed the usb driver but still no read from the Actisense NMEA Reader and navigation software. cannot upgrade the firmware too.
Looking for any good solutions ASAP.
