SteerMouse vs USB Overdrive (2026): which should you pick?

Pick SteerMouse if

• Fits if you have a third-party USB or Bluetooth mouse with extra buttons on a Mac
• Works for per-app button setups

Look elsewhere if

• Not for you if you use Apple's Magic Mouse or Trackpad, as neither is supported
• Skip it if you use Windows or Linux, since it is Mac only
• Pricey if you upgrade often: major upgrades like 5.x to 6.0 are charged
• Watch out: settings from version 4 are not carried over to version 5, and older Macs need older builds

Pick USB Overdrive if

• Fits if you use a trackball or gamepad on a Mac and want it remapped
• Works for people who can live with a login reminder instead of paying

Look elsewhere if

• Not for you if you use an Apple mouse, trackpad or keyboard, as none is handled
• Skip it if your Mac is older than macOS 15, since version 5.4 needs it
• Watch out: version 4 or earlier must be uninstalled before 5.x
• Watch out: the vendor says it may ask for a voluntary upgrade fee at a future major release

SteerMouse

• Does not support the Apple Magic Mouse or Magic Trackpad, and some special buttons may not work.
• Version 5.8.2 needs macOS 12 Monterey or later; older macOS versions use older builds.
• Major upgrades, such as 5.x to 6.0, are charged for.
• Settings from version 4 are not carried over when moving to version 5.

USB Overdrive

• Does not handle any Apple mouse, trackpad or keyboard, because that would remove native macOS support.
• Version 5.4 runs only on macOS 15 and later; older releases are for earlier systems.
• Version 4 or earlier must be uninstalled before installing version 5.x.
• The vendor says it may ask for a voluntary upgrade fee at a future major release.

Scroll tuning

Adjusts scroll acceleration and sensitivity, and has an auto-scroll option for hands-free scrolling.

Cursor snapping

USB Overdrive

Wide device support

Works with USB and Bluetooth mice, keyboards, trackballs, trackpads, joysticks, gamepads and other gaming devices from almost any vendor.

Scroll axis options
