Hey, bro, I think I've found a solution: I installed the SoundControl software, enabled the "Force Soft Volume Control" option. Yay, the volume is now adjustable! Hope this helps you too! Screenshot. Source: about 1 year ago

I haven’t installed it yet, I’ve got a few days off and don’t want to waste the trial period. This is the one I bookmarked from the ones I found: https://staticz.com/soundcontrol/. Source: over 1 year ago

IDK whether a 3rd party software audio mixer would help; you may download a trial here: https://staticz.com/soundcontrol/. Source: over 1 year ago

I've used Smooze [1] in the past. It has a ton of features, but I really just need it for turning off mouse acceleration and making the scroll wheel usable. Glad to see an open source option. [1] https://smooze.co/. - Source: Hacker News / 12 months ago

Smooze is the best app I have found to make using mac with a non-mac mouse even remotely usable. Really wish Apple would care a little more about mouse support. Source: about 1 year ago

Mac unfortunately isn’t the best at supporting third party mice and their additional buttons, for your specific case, the only app that I know of that offers a similar option would be smooze. Source: about 1 year ago

What mouse are you using? - SteerMouse is a nice app that can remap buttons. - Smooze I think also had some options for buttons. Source: over 1 year ago
