System Preferences > Mouse or Trackpad (more Mac users use the trackpad than a mouse these days) give you plenty of options for tracking speed, right click, and gestures. If you’re happy with your Mac’s pointer, good for you. If not, there’s SmoothMouse. It’s free. And smoother.
Mouse? Or, Pointer?
Most of us understand the term ‘mouse’ even if all we use is the built-in trackpad on our Mac notebooks. Personally, I prefer onscreen pointer, which is more precise and fits both.
Regardless, SmoothMouse is a Mac Preference Pane utility which adds more controls to the mouse and trackpad.
According to the SmoothMouse developer the Mac’s mouse and trackpad controls could be improved and that’s what SmoothMouse does.
Simply put, the way OS X handles the onscreen pointer’s movements across the screen results in a lag (which some can see and some have documented and some cannot see), which is more reduced in Windows PCs.
SmoothMouse improves the acceleration of the onscreen pointer (mouse or trackpad for average folks). If you don’t notice the lag then try SmoothMouse. If you can’t see the difference, than it’s not a utility you want or need.
Gamers, graphic designers, and Mac users with larger displays (more pixels), and connected displays generally notice the lag issue more than average Mac users.
SmoothMouse works much the same way for mouse as it does for trackpad. Select the Acceleration option from the dropdown menu. Adjust the Velocity from slower to faster using the slider bar. You’ll need a little trial and error to find a position that works for you and your Mac’s screen.
In my tests on a Retina display I could see an improvement of pointer acceleration across the screen, but not on every application; especially some games. I can see why Mac graphic designers would appreciate the extra controls provided in SmoothMouse and you can’t beat the price tag (none).
