I want a certain setup but I'm not exactly sure what I need and I'm hoping I can give you guys my scenario and maybe you can point me in the right direction. I own an iPhone and an iPad 3. I want an iMac and ATV. I want to be able to stream high quality video from the iMac in my office to my HDTV in my living room. Also mirror and do all the cool stuff Mavericks will offer. Its confusing to me because I want flawless playback so I'm figuring I should wait for the next iMac with .11ac. It gets a little tougher because the router is in the living room and putting it in the office is not an option hence waiting for a .11ac equipped iMac. So what would I need to do? I'm thinking a .11ac equipped Airport device in the living room connected to my router along with the ATV then a .11ac equipped iMac in the office? Is that right? Can you even connect an ATV via Ethernet for mirroring through the router (like a PlayStation 3 with streaming) or does it need to use wifi? If so since it only does .11n then is all this effort a waste of time? Or am I over thinking this and there is a better way of doing this?
