Is there a 3rd party program that can change the cursor size? [duplicate]
Occassionally I use Mouse Locator when giving demos to help the audience track my mouse movements. Mouse Locator doesn't increase the size of the mouse pointer per say, instead it "paints a target" around the pointer when you start moving the mouse. The target makes it easier to locate the pointer location. Omnidazzle also does this, but the effects are flashier.
If you open System Preferences>Universal Access>Mouse & Trackpad, you can adjust the cursor size to be larger. To my knowledge, there is no third party application that will do this since it is allowed natively. Hope this helps!
Yolo mouse, It can change both size and color you are also able to change on the fly. You can also import different styles and use them ans well in small medium and large.
