How to clean up your Mac before screen recording

A screen recording is a screen share that never ends. Everything visible gets captured, permanently, and usually at a resolution where file names are perfectly readable. Ten minutes of setup saves re-recording the whole thing.

Clear the frame

Do these before you hit record, not after, because a recording cannot be edited the way a live call can be corrected.

1. Hide desktop icons. File names are the most common leak in published tutorials.
2. Hide desktop widgets. The calendar widget shows event titles; the stocks widget shows what you hold.
3. Auto-hide the Dock, or at least remove the recent apps section from it.
4. Hide the Stage Manager strip if you use Stage Manager — those thumbnails are live and readable.
5. Turn on Do Not Disturb. A banner in an otherwise good take means recording it again.

Turn off the screenshot thumbnail

This one is specific to recording and catches almost everyone. Take a screenshot while recording and macOS floats a preview in the bottom-right corner for several seconds — straight into your footage.

# save screenshots to disk with no floating preview
defaults write com.apple.screencapture show-thumbnail -bool false; killall SystemUIServer

# undo
defaults write com.apple.screencapture show-thumbnail -bool true; killall SystemUIServer

The System Settings route is in the screenshot thumbnail guide.

Things that only matter on camera

• Your menu bar is in every frame. Some apps display account names or ticket titles there; check yours at recording resolution, not at a glance.
• Browser autocomplete. Typing a URL on camera offers your history as a dropdown. Use a clean browser profile for recordings.
• Notification badges in the Dock show unread counts, which date a recording and look untidy.
• Your wallpaper appears every time a window moves.
• Screen resolution. Recording at full retina resolution makes text unreadably small when played back in a smaller frame. Drop to a lower scaled resolution first.

Do a ten-second test take

Record ten seconds, stop, and watch it back at the size your audience will actually use — often a phone or an embedded video player rather than a 27-inch display. You are checking two things: whether text is legible, and whether anything is in frame that should not be. Both are cheap to fix now and expensive to fix after you have recorded twenty minutes of narration.

Then put your Mac back to normal afterwards. A machine configured for recording is a mildly irritating machine to work on, and hidden desktop icons are exactly the sort of change people forget they made and then spend a week confused by.

Common questions

How do I stop the screenshot preview appearing in my recording?

Turn off the floating thumbnail with defaults write com.apple.screencapture show-thumbnail -bool false, or in the Screenshot app's Options menu.

Do notifications appear in screen recordings?

Yes, banners are captured like anything else on screen. Turn on Do Not Disturb before you record.

What resolution should I record at?

Lower than your display's maximum. Text recorded at full retina resolution becomes unreadable when the video is played back in a smaller frame.

Does hiding desktop icons affect my files?

No. It changes only what is drawn on the desktop; the files stay in your Desktop folder and are reachable in Finder.

Should I use a separate user account for recording?

For published tutorials it is the most thorough option, since nothing personal exists in that account at all. For occasional recordings, hiding the clutter is usually enough.

If you record regularly

Make the setup and teardown one action each rather than a ten-item routine, otherwise it gets skipped on the day you are in a hurry — which is the day it matters. Meeting Mode applies and reverses the whole set in a click.
