If you ever struggle to find your Mac’s cursor then I recommend that you use MouseLocator. This free application puts a halo around the cursor to help your eyes locate it. You can configure how long the halo is displayed. It can be displayed for as little as half of a second, permanently or somewhere in between. You can also control how long the cursor must be idle before the halo will re-appear.
I find that MouseLocator is popular with people who use very large monitors or whose eyes are tired. I do a lot of computer-based presentations and I consider MouseLocator to be an indispensable tool. When I’m projecting my laptop’s display onto a large wall, MouseLocator helps audience locate and track the cursor as I move it around the computer screen.
