How do I use QuickTime Player provided with the Mac OS to Perform screen projection

  1. First connect the iPhone to the Mac using a USB cable.

  2. Go to the Application Center and open QuickTime Player.

  1. In the menu bar of File, find New Movie Record.

  2. In the QuickTime Player recording interface, find the red Record button and click the arrow next to it.

  3. Select your mobile phone from the drop-down menu, and you can project the mobile phone screen onto the computer.

Of course, this method, in addition to the screen, can also record your phone’s screen operations into a video. But this method doesn’t work with video and audio screens, because the Mac doesn’t play the phone’s sound simultaneously.
