A:
This keyboard combo was made for Windows, not mac.
The mouse works on my macbook pro M1 Pro, but the keyboard is often unavailable, so it is not reliable and therefore useless
I installed the Logitech Options+ app (downloadable on Logitech website). This app only picks up the mouse, not the keyboard. You can change a few settings for the mouse (middle button, tracking speed, wheel speed), but none of the keyboard multimedia keys can be tweaked.
