Hi! Recently I have bough a keyboard and a mouse from razer, but I could not configure them because Razer Synapse it is not working on the latest macOS. However, I was just about to return them since I cannot configure them properly. Just when I was about to give up i found this soft Razer macOS ( https://github.com/1kc/razer-macos ) that lets you configure and play with the devices lightning. Also, for the audio EQ, the best soft that I find is "Boom2:Volume and boost eq" that you can find on app store. Hope this helps anyone with the same problems. Greetings!
