As a datapoint from someone who uses razer software on macs: I use razer hardware with my macbook pro at work. I have a razer keyboard, a pretty LED firefly mouse pad and a pretty LED razer mouse and razer's "Synapse" software mostly works, but I definitely feel like razer has a long way to go with software in general. It forgets settings, the update process is weird, and compared with Corsair or Steel Series software it is definitely not as good. I tried the Razer nabu watch and its software was worse in every way when compared to a pebble. Bluetooth connectivity had issues, step tracking, sleep tracking, it was all significantly worse than a PT. I love razer hardware, but their software skills seem to be still catching up.
