Does airplay from apple tv work the same for macbook air mid 2011 and macbook air mid 2012 model? Or is the 2012 model faster? Is there any delays?

Hi Jorgeper,

The Airplay technology on both will work and is the same. The later model will be a bit faster but considering the lag you will get on both is barely an issue.

There is a delay over Airplay that you will notice with your bare eye.

I found it working fine for presentations and some work but playing movies is not there just yet. It does work but even on the latest fastest MacBook Pro and Apple TV 3rd generation there is a visible lag and occasional stutter.

This will also depends heavily on the WiFi connection you use and if you can connect the Apple TV via ethernet port (cable) this improves the speed.

I use my 2011 MBA to show videos and movies as well as to play music over my home theatre. Works great. Which computer you have isn't likely to matter - the big question is whether your WiFi network is up to the task. If your WiFi base station is far away from where your computer will be or if you have any kind of interference you may have some stuttters.

I was referring to better specs / faster performence of the computer in general.

The real bottleneck for Airplay is the speed of the WiFi network.
As mentioned above it always helps to wire static devices such as Apple TV.
