How to Record an App Demo on Mac

Updated November 14, 2026 · By KIM YOOGEON, maker of Quibble

To record an app demo on a Mac, set up clean sample data, plan one task to show, record your screen while you do it, trim the mistakes, and export an MP4. Zooms, highlights and captions help viewers follow small buttons and small text.

This guide is about the recording itself: how to show one Mac app on screen. If you need help with the story, the script and the sales side of a demo, read how to make a SaaS product demo video.

Step 1: Prepare the app

Most problems in an app demo come from the setup, not the recording.

  1. Use sample data. Fill the app with believable fake data. Do not show real customers or private files.
  2. Start from a known state. Log in, open the right screen and reset any settings you will change.
  3. Quiet your Mac. Turn on Do Not Disturb and quit chat and mail apps so no notification pops up.
  4. Make things readable. Use a larger text size in the app if you can. Small text is hard to read on a phone.
  5. Clear the desktop and close windows you will not use.

Step 2: Plan one path

Choose one task and list the clicks in order. Example: "Create a project, add a task, mark it done."

Keep it short. A viewer who wants to see one feature will not watch a tour of ten. Do one run without recording, so you know where every button is.

Step 3: Record the demo

With the free Apple tools, press Shift-Command-5, choose a window or area, and click Record. This gives you a video and nothing else. It works for a simple demo.

With Quibble:

  1. Open the app you want to show.
  2. If you want your face in the corner, turn the Camera switch on first. Then press ⌥⌘R to start recording, and choose what to record.
  3. Do your path. Move the mouse slowly, and say what you are doing.
  4. When a small thing matters, hold ⌘ and draw around it. A yellow circle or box is drawn into the video.
  5. Press ⌥⌘R again to stop. The editor opens.
The video zooms into the clicked button, then back out

You do not need a perfect take. If you make a mistake, pause, start the step again, and cut the mistake out later.

Step 4: Edit

A demo edit is mostly removal.

  • Cut loading and wrong clicks. In Quibble, press B to turn on the Split tool, and click the timeline where the bad part starts. Click where it ends, press B again, click the part between, and press Delete.
  • Check the zooms. Zoom on clicks is on by default. You can turn it off with Use Zoom or add one by hand with Add Zoom.
  • Fix the captions. They are ready a few seconds after you stop, in English or Korean. Fix any wrong word.
  • Choose the frame. For a vertical video, use the Frame tab and choose Fit or Fill with 9:16. See vertical screen recording on Mac.

Step 5: Export

Press Done Editing. Quibble makes the finished MP4. If you press it again after more edits, the new MP4 replaces the old one. For music and titles, use Send to CapCut, which makes a folder with your video and SRT captions.

Why zooms, highlights and captions help an app demo

These are aids, not magic. A clear path and a short video matter more.

What Quibble does not do

  • It records the Mac screen, not a phone's screen.
  • It runs only on Macs with Apple silicon, with macOS 15 or later.
  • It has no cloud upload or share links, and no Windows version. You share the exported file.
  • For many tracks, music or effects, use a larger editor.

Cost

You can record and edit without a key. Saving the finished video needs a license: $7.99 per month, $79 per year, or $129 once.
