Airplay On Apple Tv

By • 8:48 am, July 11, 2012 • • If your Mac wasn't made in the last year and a half, you won't be able to do this. With OS X Mountain Lion, AirPlay Mirroring is finally coming to the Mac, allowing some Macs to stream audio and video directly to their Apple TV. ‘Some’ is the operative word here. Much to the disappointment of the vast majority of Mac owners who will be installing Mountain Lion on their machines in a couple weeks time, AirPlay Mirroring will only work if you have an iMac, MacBook Air or Mac Mini from mid-2011, or a MacBook Pro from early 2011. Office 2011 for mac mega. There’s been a lot of conspiracy theories floated about this requirement. Some have argued that it’s forced obsolescence on Apple’s part, trying to force older Mac owners to upgrade their machines. Others have suggested that the reason Apple requires a Mac from 2011 or later is because of in Intel’s chips that didn’t debut until last year.

The truth of the matter, however, is far less sensational. The reason you need a 2011 Mac to make use of AirPlay Mirroring in OS X Mountain Lion is because the graphics in older Macs just don’t cut the mustard. How can that be? It’s simple: the secret sauce that Apple requires to make AirPlay Mirroring work is on-GPU H.264 encoding, or the ability to compress video on your device’s actual graphic chips without calling upon the CPU. “At least as far as Apple’s concerned, it’s not really possible for older Macs to support AirPlay Mirroring,” Sid Keith of, an OS X app that allows you to mirror video to the Apple TV. “Without physical hardware support, mirroring eats a huge chunk of CPU, which means performance would be hindered to a point Apple would never allow.” “Without physical hardware support, mirroring eats a huge chunk of CPU, which means performance would be hindered to a point Apple would never allow.” It’s not just Macs that can’t use AirPlay Mirroring if they are older than 2011: even on the iOS side of things, you need a minimum of an iPhone 4S or an iPad 2 to use AirPlay Mirroring on your Apple TV. Because older iOS devices don’t have on-GPU H.264 encoding either.

White Unibody MacBook Q&A @ EveryMac.com. With EveryMac.com's 'White Polycarbonate Unibody' MacBook Q&A you can get answers to all of your questions about the MacBook models that are molded as one piece of white polycarbonate (which Apple refers to as the 'Late 2009' and 'Mid-2010' MacBook models, and that share model number A1342). Airplay Mirroring in Mountain Lion on Mid 2010 Macbook Pro? I just bought and installed Mountain Lion for my Macbook Pro and the first thing I wanted to try out was the mirroring feature. Unfortunately, the mirroring icon does not appear in my upper bar.

“The new generation of Intel and AMD chipsets that debuted in 2011 are definitely required for this to work up to Apple’s specifications,” agrees AirParrot’s lead developer, David Stanfill. “For the modern [Intel and AMD] chipsets Apple has written drivers to access the on-GPU H264 encoding,” says Stanfill. “Since the image of whatever is on screen is already in your graphics’ frame buffer, all Apple needs to do is the scaling (the most expensive part of AirPlay Mirroring, which is why you have ‘Best for AirPlay’ resolutions that are 1:1), the color conversion (H.264 video needs YUV color space vs. RGB), and the actual encoding itself right on the GPU.
