How to draw on your Mac screen while presenting

THE SHORT ANSWER

macOS can't draw on the live screen by itself. Markup only works on screenshots. To draw over any app while you talk, use your call app's annotation tools (Zoom, Teams, Meet) or install a screen annotation app like ZoomIt for Mac (free) or Overlaid.

Pointing at things with your cursor works right up until someone asks 'which one?'. Drawing a quick circle or arrow on screen is faster and clearer, but your Mac doesn't have a built-in way to do it on the live screen.

Here's every option we know of, starting with the free ones.

METHOD 01

Screenshot Markup

Free, built in

Take a screenshot, then draw on it. Good for something you'll send afterwards, not for live presenting.

  1. 1Press ⌘⇧4 and drag over the area you want.
  2. 2Click the thumbnail that appears in the bottom corner.
  3. 3Use the Markup toolbar to draw, add shapes and text, then share or save.

GOOD

  • +Already on every Mac
  • +Fine for async feedback

NOT SO GOOD

  • −Not live: you draw on a picture, not the screen
  • −Breaks the flow of a call

METHOD 02

Your call app's annotation

Free with Zoom, Teams or Meet

Zoom, Microsoft Teams and Google Meet all have some form of annotation on a shared screen.

  1. 1Start sharing your screen.
  2. 2In Zoom, click Annotate on the share toolbar. In Teams, select Annotate from the presenter toolbar. In Meet, annotation is available to paid Google Workspace users.
  3. 3Pick a pen and draw.

GOOD

  • +No install
  • +Viewers can draw too, if you allow it

NOT SO GOOD

  • −Only works inside that one app
  • −Not in recordings made with other tools
  • −No keystrokes or zoom

METHOD 03

ZoomIt for Mac

Free, open source

Microsoft's official Mac version of the classic presentation tool. Freezes the screen, then lets you draw on it.

  1. 1Install with Homebrew: brew install --cask zoomit
  2. 2Grant Screen Recording when asked.
  3. 3Use its shortcut to enter draw mode, then draw on the frozen screen.

GOOD

  • +Free
  • +Also records, snips and has a break timer

NOT SO GOOD

  • −Draws on a frozen capture, so you can't keep using the app underneath
  • −Needs Homebrew to install

// WHICHEVER YOU PICK

THREE TIPS.

Share your whole screen

Annotation apps draw in their own transparent window. A single-window share won't include it, so viewers see nothing. Share the entire screen.

Use fading ink on calls

If your app supports it, set marks to fade after a few seconds. You'll never have to stop and clear the screen.

Go thicker than you think

Video calls compress hard. A thin line that looks fine on your screen can vanish for viewers.

// FAQ

QUICK QUESTIONS.

Only on screenshots, with Markup. For the live screen you need either your call app's annotation tools or a screen annotation app.

Yes, as long as you share your entire screen. Drawings from annotation apps are a separate layer, and single-window shares don't include it.

Yes, with Sidecar. Use your iPad as a second display and the Pencil works as a pointer, so any screen annotation app, Overlaid included, can be drawn on with it.
