How to Make a Screen Recording on a Mac
One of the best ways to teach someone how to do something is by showing them, which is where macOS's screen recording comes in. For example, I have used this process to demonstrate how random number drawings performed on my MacBook are truly random.
Before you decide to record, think about if your video could benefit from narration. If so, a USB mic or a headset with in-line mic may be worth plugging into your machine. Here's how to make a screen recording on a Mac.
1. Click Space + Command, and then type "quicktime player."
2. Select QuickTime Player.
3. Click File.
4. Select New Screen Recording.
5. Click the down-pointing arrow next to the record button.
6. Select an audio source if you want to narrate the video. If you want your video to be sound-free, select None.
7. Click the record button.
8. To start recording the whole screen, click anywhere on the screen. To record only a portion, click and drag your cursor to draw a box.
9. To stop recording, click the Stop button in the menu bar.
10. To save, first click File.
11. Then select Save.
12. Name your recording.
13. Click Save.
You've created a screen recording!
