Rather than a 604, consider a 502. Not sure what the OP is referring to with the software being way worse - Logitech G-Hub works perfectly on the Mac and has a huge amount of tracking, sensitivity, and precision settings available. The scroll wheel on the 502 is plastic, and on the 604 is metal. The 604 does have a lot of additional programmable buttons, if that is useful.
The 502 and the 604 are then best mice I've used. I did have an MX Master a few years ago (not the current model), and found its tracking accuracy to be poor.
