Some people find it hard to find the mouse pointer at times, particularly on a large screen or when working in Dark Mode or in apps with dark interfaces. Yes, there is a slight difference between a cursor and a pointer, but you can use them interchangeably*. You’ve long been able to increase the size of the pointer generally and also zoom it temporarily by shaking it, but in macOS 12 Monterey, Apple now lets you change the color of the pointer. That could be a boon to those who have trouble seeing it otherwise. Go to System Preferences > Accessibility > Display > Pointer, click the Pointer Fill Color box, and choose a different color in the color picker. You can also choose a different Pointer Outline Color if that’s helpful. After customizing it, if you decide you prefer the old black-and-white version, click the Reset button.
(*In tech-speek, a cursor is any indicator used to show the current position for user interaction on a display device, such as your computer monitor or iPad screen, that will respond to input from a text input or pointing device. The mouse cursor is a pointer, when it is displayed as an arrow, or pointer stick.)
