How to Record Your Screen On A Mac Using Quicktime
Open QuickTime Player.

A Screen Recording box will pop up on your screen.
Click on the white down arrow and select use the built-in microphone for audio.
Once you are ready to record, you can choose to record part of the screen or the whole screen. If you just want to record part of the screen click the red record button. You will see a message that tells you to drag to record part of your screen, so drag a marque across the area you want to capture. Once you have the area selected, click the record button again.
Alternatively you can record the whole screen. Just click on the red record button and then click the screen anywhere to begin recording.
Once you are ready to finish recording, right (control) click on the QuickTime icon in the Dock and choose Stop Recording from the menu.
