This may not be new for many iOS developers who tried Yosemite beta but new for a new Yosemite user.<p>I was using Reflector all the time to share my iOS device screen with my MacBook for demos. With OS X Yosemite, QuickTime has a fantastic feature to record from iOS device connected to your mac (over lighting cable).<p>- Connect your iPhone/iPad runs iOS 8.
- Fire up QuickTime player and new movie recording
- Choose iOS device from the drop down menu next to record button.
- Even the microphone and camera can be used.<p>Looks like this is more of a developer feature to prepare app preview videos for AppStore.
