After trying to run synapse I came across this software. Honestly, this made me not to return the razer products, since they do not support macOS users, but I really like their products so finding this software really makes me happy. Kudos to the one who made it !
On launch, Razor macOS presents only a blank, black window with "Please select a device to configure," but no controls or anything else. MacOS 13.5.1 (22G90).
Advice?
