Record your screen in QuickTime Player on Mac
Using Screenshot in the QuickTime Player app, you can make a video recording of your computer screen. You can open the recording in the app and save it on your Mac.
In the QuickTime Player app on your Mac, choose File > New Screen Recording to open Screenshot and display the tools.
You can click Options to control what you record — for example, you can set the location where you want to save your screen recording, or include the pointer or clicks in the screen recording. See Take screenshots or screen recordings.
Click Record. To stop recording, click the Stop Recording button in the menu bar (at the top right of your screen) or use the Touch Bar.
Depending on where you chose to save the recording, an app may open.
