I see that it's been tested up to MacOS Sierra. I wonder if this could be used on Catalina.

I've read online that even USB floppy drives are no longer supported in macOS. Which is disappointing.

It can be used up to Mojave. The current drivers don't work on Catalina. We hope to release an update soon, but there is no ETA.

Regardless of the support of standard USB floppy drives this one wouldn’t work anyway because it uses a custom protocol.
