MouseUp is a menu bar app for macOS that repairs the two things desktop mice get wrong on a Mac: clicks that register twice and wheels that scroll in steps instead of gliding. It works with Logitech, Razer, SteelSeries, Corsair, Microsoft and Apple mice without installing the manufacturer's own driver.

A 200 ms click debounce drops the second half of a ghost double-click, so a worn switch keeps opening one window instead of two.
Wheel input becomes smooth scrolling, with Cmd plus scroll mapped to zoom in any app and the mouse side buttons wired to Safari back and forward.
One lifetime license covers 2 Macs on macOS 12 or later, with lifetime updates, priority support and a 7-day refund, after 16 releases since March 2026.

Battery level, DPI and polling rate for supported mice are read in the same panel, which makes Logi Options+, Razer Synapse and SteelSeries GG unnecessary. Black Friday takes the lifetime license from $7.99 to $4.00 through December 5.
