I just want to update this post/video and say that AirDroid will not work with Android 4.3 as far as using the Screenshot aspect. The app still works but not the mirroring on 4.3.
I have been using Android solely for 3 months now, since the end of January and the one thing I couldn't figure out was how to mirror my screen on my iMac like I can with my iPad and AirPlay. AirDroid is an app I have been using since the beginning but didn't realize it worked as a mirroring app. It does, someone commented on a post on Google+ about this yesterday. Now I can finally do Android App reviews. Yay for me.
