How to record your screen on a Mac using the QuickTime application
To record your screen instead of taking a photo, simply launch the Quickytime.app from Finder or Launchpad and press Control+Command+N on your keyboard.
- When the black box appears labeled “Screen Recording,” click on the Record button.
- Follow the on-screen instructions to finish recording your screen.
If you are a diehard Apple fan and also own iOS devices, you can take screenshots with them by pressing the Home and Lock buttons at the same time. The image will be saved to your camera roll and you can access it through the Photos app.
