Companion software for hardware accessories has historically been terrible. I can't recall an instance where I wanted to keep companion apps besides drivers running in the background.
Whenever possible I would only open them for as long as I needed to configure something, then killed the process if it wasn't necessary.
Thankfully on the Mac I haven't encountered a need for those yet.
It really is quite incredible the unrewarded, often thankless (except that which we're doing now) effort that must go into that.
I had an issue recently with missing drivers for a network card (my fault, I deleted the kernel modules, it had been and now is again working), and it just made me think exactly what you're saying, how glad I am that someone's provided this.
I’d include Razer in the dumpster fire pile. In my estimation, the custom drivers of most HID products seem to be as bad as printer drivers back in the late 1990s/early 2000s. Actually worse because of all the RGB nonsense and cloud bullshit.
I use a razer orbweaver as a macro keyboard, and even though its still for sale it doesn't work with the current version of Synapse. So if you have an orbweaver and another peripheral, you need to run both synapse 2 and 3.
