Many times the best place to look for something you’ve lost is down the back of the sofa, however, this is not helpful if the item lost is the cursor on you Mac’s screen. A feature that has been available since the release of El Capitan in September 2015 is the ability to make your cursor reveal itself by simply moving your mouse quickly or running your finger rapidly back and forth across the trackpad, this makes the cursor increase in size. Once you’ve located the elusive cursor, stop and it will shrink back to its normal size.
Open System Preferences and select Accessibility.
Once the Accessibility panel is open select Display on the left side and ensure the ‘Shake mouse pointer to locate’ checkbox is ticked (img.1).
