I am running the Firefly mousepad under MAC OS Catalina Beta with Synapse 2. Even when the mousepad is plugged in and shows under apples USB devices area it says "Please connect a razer synapse enabled devices" in Synapse. I reinstalled Synapse and for a few minutes it did show the Firefly but the LEDs would not change at all. Once I restarted the app it came back not finding the device. I am sure this has to do with beta software but I figured if there's any hope that someone got past this I would post to see. Thanks!
