When I started using SketchUp Pro on my old iMac, I was using a Macintosh mouse with a small roller and that work great.
Then I tried a Magic Mouse and that was not so great since there is no roller on it.
After that I bough a mouse with a roller wheel and this worked great on all Mac that I used.
Actually I use Logitech MX Master 3 for Mac and it works perfectly with SketchUp and all other softwares on my MacBook Pro.
