Today I bought a Firefly v2 and then found out that the Synapse 3 is not available for Mac. It was such a bummer and I was about to return it, and then I found this awesome project (Thanks to Reddit)



I was amazed that this forum doesn't have a dedicated thread for this project and it was referenced in only a couple of posts here. So for anybody come here looking for a solution, there is a community driven project with some functionalities: https://github.com/1kc/razer-macos



Looking at the commit history, it seems to be quite well maintained with regular updates as well. For me so far it worked well on Catalina and it is supposed to work on Big Sur too
