Highlight the Cursor

In Presentation Mode on macOS, press c to show or hide the cursor effect. It starts off each time you begin presenting or switch presentation modes.

On macOS 15 or later, open Deckset > Settings > Presentation and find Cursor Highlight. Choose Highlight to draw a colored highlight around the pointer, or Spotlight to dim the slide outside a soft-edged area around the pointer. The color control applies to Highlight and is disabled for Spotlight.

Choose the style in Settings, then use c while presenting to turn it on when you need it. The cursor effect is a presentation control; it is separate from the spotlight slide transition.
