Calm down, 10.8's AirPlay restrictions are technical - not planned obsolescence

Summary: Apple has restricted AirPlay mirroring in OS X 10.8 Mountain Lion to 2011 and newer Macs and its got users of older hardware howling mad. But it's not planned obsolescence on Apple's part, the feature requires Intel Quick Sync Video for optimal performance.

10.8 AirPlay restrictions, technical limitation or planned obsolescence? Jason O'Grady

One of my most anticipated features in OS X 10.8 "Mountain Lion" ($19.99, Mac App Store) is AirPlay mirroring. Introduced in iOS 5, AirPlay mirroring allows you to mirror your iPad 2 or 3's screen wirelessly to any display with an HDMI input -- flat panel monitors, televisions and projectors -- via a $99 Apple TV. And it's brilliant.

Monday night is "tech night" at my friend's house and we used to take turns plugging our iPads into his flat-panel television (to demo apps and play funny YouTube videos, etc.) with the Apple Digital AV Adapter -- a klunky $40 dongle that connects to the dock connector port on the bottom of the iPad.

AirPlay mirroring does away with the dongle and cable and replaces it with an Apple TV. Instead of "cabling up" to the TV, simply select the Apple TV from the source list and stream video to your TV over Wi-Fi. It's even more useful for giving presentations using a projector.

Ever since AirPlay mirroring came out for iPad I've wanted it on my Mac and that's what 10.8 delivers. But with a catch.

With 10.8 Mountain Lion installed you can mirror your Mac display (not just your iPad) to an Apple TV -- great for watching movies from Hulu and network TV websites. It's especially useful for cable cutters without traditional cable service.

The problem is that AirPlay Mirroring will only work with Macs shipped 2011 or later. Here's the requirements from the footnote on Apple's 10.8 features page:

AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).

(Note that the Mac Pro is noticeably absent despite being revised on June 11, 2012.)

Since the listed Macs are only a year old, a lot of users with older Macs will be excluded from this new feature. Apple's discussion forums are lit up with users howling mad about the snub and "planned obsolescence." (This thread alone has 1,600+ views).

Did Apple put in an artificial restriction to sell more Macs? Or does AirPlay mirroring need the faster CPU/GPU/networking found in newer Macs? 

Software like AirParrot ($10) points to a genuine plot by Apple to separate you from your hard-earned money. It works with Snow Leopard (10.6) and Lion (10.7) and with Macs as far back as mid-2009. (You can get a free 10 minute trial from their Website.) The problem is that although it works, performance on older Macs isn't optimal. 

Although I love a conspiracy as much as anyone, it looks like Apple's decision might be attributable to a legitimate hardware requirement, or at minimum, a subject judgement call on quality.

The best theory is that Apple uses Intel's Quick Sync Video architecture for AirPlay encoding in Mountain Lion which is why it requires 2011 or newer hardware. Apple doesn't make a habit of releasing features that it knows will result in sub-par performance. As one TidBITS commentor notes "This is the same reason they don't show the water-drop animation if you don't have a graphics card that can reasonably support it."

According to some accounts Intel Quick Sync Video is 5x faster than GPU encoding, and 10x faster than software encoding. So it looks like Apple's restricting AirPlay mirroring in 10.8 to modern Macs to provide the best user possible possible. Imagine that.

It looks like everyone else will have to use AirParrot.

  • Sure

    Come on! Yeah, they want to let Intel provide the best experience rather than doing any work on their end or paying for Air Parrot. I will say this, Apple is a frugal company for being so filthy rich. But as they say, a penny saved...

    • Are you serious?

      The hardware was not there pre-2011.

      Apple chose hardware that could perform the task in later models.

      Either way Apple has done the work.

      What do you think Apple sits inside the computer and decides if they can be bothered doing the labour of encoding?

      Apple has designed the software architecture and a lot of the hardware architecutre.

      Apple has developed all of the code to do the job with or without the Intel chipset.

      Apple has decided that the overhead of using the software without the hardware acceleration is not good for the user.

      They have not decided that the Intel genie will magically do their work for them

      Are you stupid, ignorant or a shill astro-turfing?
      • before you ask

        I am one of those who bought 10.8 hoping for the AirPlay feature.

        If this was not a resonable move by Apple I would be quite upset right now.

        I have considered buying Air Parrot, but if a software encoding is going to cause issues I need to think carefully.

        In my case for the moment it doesn't matter too much to me as my iMac is right by my TV, so I just need an extra HDMI cable to plug the Mac back in like it was before.

        The previous HDMI cable is now on my AppleTV.

        My AppleTV of course still provides play from iTunes, I assume this is because the video in iTunes does not need re-encoding for AirPlay.

        Also iTunes sharing means I get to use AppleTV to access my iTunes Library.

        So although a little disappointed, still very happy I got the AppleTV and not majorly disadvantaged.
        • Why didn't you buy AirParrot for half the price of

          the OS upgrade?
      • Name Calling

        I'm none of those things Richard, I'm just telling the truth.

  • So AirPlay is not an Apple R&D but rebranding of Intel Technology


    Why am I not surprising at all? So much innovation as in integration.
  • Airplay was on Mountain Lion Beta 2 worked on 2008 Macbook pro

    It was included beta 2 Mountain Lion - it was working on 2008 Macbook pro but it was not included final release...go figure...time to upgrade to Retina Display Macbook Pro - got $2700?
  • Stream 1080p video via airplay

    This is a whack of data delivered from iTunes on my 2010 MacBook Pro to my Apple TV2 ,I know the ATV2 is only 720P but the file isn't. Yet the cutting edge OSX is not able to mirror my desktop on the same hardware? I think this article is weak.

  • If the GPU is Intel based ;).

    "According to some accounts Intel Quick Sync Video is 5x faster than GPU encoding"

    If the GPU is Intel based ;).

    I'm willing to bet that a Radeon or GeForce can still run rings around it.
