@quasaur The issue at hand here is the driver hasn't been written for Apple Silicon by Prolific yet.
There are a number of (not-free) apps in the Apple App Store that can supplant the driver need and allow you to do the direct-action in the OS to the device -- I've used a few of these over the years myself. And I haven't found a single USB->Serial device it cannot process yet.
You may find recommendations in the forum here from other users for Console applications for macOS that would fit the bill. I know of at least two that have 15- or 30-day free, no subscription trials that you can test run with to see if they fit your needs.
