If you search online to find a way to mirror your iPhone or iPad on your Mac, you’ll get several different results. Most are expensive, bloated software that you don’t need. Everyone seems to be quite hushed about a hidden feature built right into macOS that lets you mirror your iOS device. That’s right, you can do this already without any additional software and it’s totally free.
All you need to get started is your iPhone or iPad, a Lightning cable and QuickTime Player.
Mirror Your iOS Device Using QuickTime:
Get out your trusty lightning cable and your iOS device. Plug it into your Mac and close out whatever annoying apps automatically open upon doing so. You won’t be needing those. Instead you need QuickTime Player. Yes, open that.
Now head up to your menu bar. Click File and then select New Movie Recording. It might be tempting to ignore these instructions and select New Screen Recording instead, but I promise that would lead to nowhere.
You should now see your face if your default camera is the built-in webcam. Say hi. Now click the tiny arrow next to the record button to open a dropdown menu. Select your connected device to instead switch the input to that screen.
You should be successfully mirroring your device at this point. There will always be just a slight delay between animations on your iPhone or iPad and the animations you see on screen, but response time is still pleasantly speedy.
