Developers just got an early preview of Apple’s upcoming iOS 11 update for iPhones and iPads today during the company’s WWDC 2017 keynote in San Jose.

The new update packs some huge new features that make iOS more powerful and easier-to-use than ever. Apple’s update is so jam packed that some of the best new additions didn’t even get some stage time at WWDC.

I recently scored an awesome second-hand sofa for my office, which means that I can sit back behind my 27-inch iMac and watch TV and movies on the big screen. But I’m used to watching everything on my iPad, I’ve been using AirServer to turn my iMac into an AirPlay screen. It works flawlessly, and this alone would be worth the $15 price.

But now a new update adds screen recording, plus support for using your keyboard’s media keys to control playback from the iDevice

Yesterday, we showed you how to record your iPhone or iPad’s screen using Reflector, an app that runs on your Mac and records the iOS device’s screen via a little AirPlay magic.

Today, let’s talk about recording your Mac’s screen. I was surprised to find out that QuickTime Player (which is already on your Mac) will do this for free. Here’s how to make the magic happen.
