You have two options: (a) if you want to record your entire screen, click anywhere on your screen to start the actual recording (b) or you may drag to select an area. When you are ready to start recording, click the red record button. You may also need to move your mouse off of this window so it doesn’t appear in front of your face. You may want to arrange your screen (where will your camera be etc?) before you start your recording. You can record your full screen or part of your Mac screen. You can change some settings by clicking the arrow next to the Record button.

Spotlight in the top right-corner of your screen, then type “Quicktime.” You can open Quicktime through the following methods:
