WheelClickНове

Your Mac has no middle button. WheelClick gives it one, on the trackpad and on the Magic Mouse. Links open in new tabs, tabs close with one click, and Blender, Fusion 360 and Unity pan and orbit as they would with a real mouse.

Four ways to middle-click on the trackpad: three-finger click, three-finger tap, fn+click and Force Click. On the Magic Mouse, click with three fingers.

Plugins when you want more: middle-drag for CAD and 3D, Windows-style autoscroll, and three-finger swipes for volume and brightness. Ignore any app in one click.

Three-finger click and tap are free forever. Everything else is $4.99 once, no subscription, with a 14-day trial.

Lives in the menu bar. Rated 4.8 on the Mac App Store. From the maker of MiddleClick (2,950+ GitHub stars).
