Getting a Mac ready to record a screencast

· 7 min read

Most botched screen recordings fail for the same four reasons: a notification slides in, the desktop behind the window is a mess of files, the screen dims or locks partway through, and the recording is at a resolution nobody can read. All four are settings, and all four can be dealt with in about ten minutes before you press record.

Here is the order that works, from the things that ruin a take to the things that just make it look unpolished.

Stop anything that can appear on screen

Notifications are the one that forces a re-record, because a message preview is not something you can cut around.

  1. Open Control Center in the menu bar and click Focus, then turn on Do Not Disturb. Choose For 1 hour so you do not leave it on all week by accident.
  2. In System Settings > Notifications, check that Show previews is set to When Unlocked at most. A banner with no preview is still a banner, but it leaks nothing.
  3. Quit chat and mail apps outright. Focus modes cover notifications, not badge counts appearing in the Dock or a window flashing to the front.
  4. Turn off Time Sensitive overrides for anything that does not genuinely need them, otherwise a Focus mode will still let some alerts through.

Then handle the screen itself. In System Settings > Lock Screen, set Turn display off on power adapter when inactive and Start Screen Saver when inactive to Never for the session. Talking for two minutes over a static screen is exactly what triggers a screen saver.

If the Mac is going to sit with the lid closed on a stand, keeping a MacBook awake with the lid closed covers the honest limits of that.

Clean up what the camera sees

Your desktop is part of the recording whether you planned it or not.

  • Hide desktop icons. Right-click the desktop, choose Use Stacks, and forty files become four tidy piles. To make them vanish entirely, move them to a folder for the duration.
  • Trim the menu bar. Command-drag menu bar icons to reorder or drag them off. A row of fourteen icons dates a video and distracts from it.
  • Set the Dock deliberately. Either pin it visible with only what you will use, or turn on auto-hide so it stays out of frame. The worst option is auto-hide with a slow reveal, which makes the pointer look like it is fighting the machine. The delay is adjustable: see make the Dock appear instantly on a Mac.
  • Use a plain wallpaper. A dark solid color compresses better and keeps the viewer’s eye on the window.
  • Open a clean browser profile if your bookmark bar has client names on it.

One more that is easy to forget: turn off autocorrect and smart quotes if you are going to type in the video. Watching a word get silently rewritten derails a demo, and smart quotes break any command you type in a terminal. Turn off autocorrect, smart quotes and substitutions has the exact toggles.

Set the recording itself up properly

macOS records screen video without anything extra. Press Command-Shift-5 to get the capture bar, with options for the whole screen, a window or a selection.

In the Options menu of that bar:

  • Microphone: pick the one you mean. The built-in mic records the room, including the fans. A headset or a dedicated mic is a bigger quality jump than anything else in this list.
  • Show Mouse Clicks: on, for anything instructional. Viewers cannot see your fingers.
  • Save to: choose a folder with room on it. Screen recordings are large, and the Desktop is the worst place to put them.
  • Timer: five seconds, so the first frame is not you reaching for the trackpad.

One resolution note matters more than people expect. On an external display, the scaling setting decides how big the interface looks in the recording, and a “more space” setting makes text unreadable once the video is compressed. Set the display one notch larger than you would work at, and record with the app window sized to the area you want rather than full screen. Why text looks blurry on an external monitor explains what scaling does underneath.

Finally, do a 30 second test recording and actually watch it. Test for audio level, for whether the text is legible at half size, and for anything in frame you did not intend.

Turning the whole setup on and off in one step

The annoying part is not any single setting. It is that there are a dozen of them, they live in different places, and after the recording you want your normal Mac back: notifications on, the screenshot thumbnail back, sleep back to sensible.

Mainspring exists for that kind of switch. It surfaces settings macOS hides as one-click power-ups, each one a real macOS setting labeled in plain English and snapshotted before it changes, so it flips back in one click. Relevant ones here include the instant Dock with no auto-hide delay, a custom screenshot folder, screenshots without the shadow or the floating thumbnail, Dock size and magnification, reduce transparency, silencing interface sounds, and never sleeping with the lid closed.

Two features fit a recording day specifically. Recipes are curated bundles applied as a set and reverted as a set (Screenshot Studio and Declutter and Focus are the ones to look at). Scenes let you build your own mix of power-ups, and a scene can apply itself on a trigger such as connecting a display, which means plugging in the capture monitor can be what puts the Mac into recording mode.

It runs locally with no account, needs macOS 13 Ventura or later, and is $29 once for up to 3 Macs with a free one-day trial. If you record twice a year, the manual checklist above is genuinely fine.

The pre-flight checklist

Run this from top to bottom before every recording. It takes two minutes once the settings are already made.

  1. Do Not Disturb on, chat and mail quit.
  2. Display sleep and screen saver set to Never.
  3. Desktop tidy, menu bar trimmed, Dock decided.
  4. Command-Shift-5 options checked: mic, clicks, save location, timer.
  5. Power connected. A Mac on battery can throttle during a long capture.
  6. Disk space checked. An hour of screen recording is many gigabytes.
  7. Thirty second test, watched back with headphones.

Afterwards, undo the sleep settings. A Mac left set to never sleep is a Mac that sits awake in a bag.

Questions

How do I record just one window instead of the whole screen? In the Command-Shift-5 bar, choose the fourth option, Record Selected Portion, and drag a box. There is no window-only mode for video the way there is for screenshots, so size the window first and draw the selection around it.

Can I record system audio as well as my voice? The built-in capture tool records microphone input, not what is coming out of the speakers. For a demo with sound, the practical workaround is to narrate over the section instead, or to add the audio separately when editing.

Should I use a separate user account for recordings? If you record regularly, yes. A clean account gives you an empty desktop, a default Dock, no personal bookmarks and no notifications from your own apps, and you never have to undo anything afterwards.
