I've been struggling with the Synapse 2 for Mac that partially works in OS Catalina. From what I've read and now heard from Razer, there is no promise of the software coming anytime soon.
As an alternative, I'm also exploring Logitech's hardware. I use both the Hex v2 and the Tartarus v2 as a work device and love the form factor, but need something I can depend on.
Has anybody been able to hack their own version of the Synapse software for Mac? I'd happily chip in.
