I’ve got a quick tip to make your Mac mouse pointer larger and easier to see and find. Start by clicking the Apple icon at the top left and choosing System Preferences from the drop-down menu.
When the System Preferences menu opens, choose Accessibility.
The Accessibility menu will open.
In the left pane, scroll down to Display.
Click on the Cursor tab.
Tick the box next to shake the mouse pointer and if you shake the mouse or move your hand across the trackpad the mouse will temporarily increase in size to make it easier to find.
To permanently adjust the size of the mouse, move down to the Cursor size silder bar. Drag the slider bar to increase the size.
