How to Disable Shake to Find Cursor on Mac OS
One of the new feature additions in newer Mac OS releases is the ability to quickly locate a mouse cursor on screen by shaking the mouse or trackpad cursor around, which causes the cursor to enlarge briefly, making it very easy to find on single or multiple display setups.
This is a useful feature particularly if you find yourself losing the cursor from time to time, but some users may not appreciate the cursor growing anytime the mouse or trackpad is shaken around or moved quickly. Thus, some Mac users may wish to disable the shake to find cursor feature in Mac OS X.
