iPhone Not Running OS X 476

Posted by kdawson from the but-but-steve-said-it-was dept.
rochlin writes "We know that Steve Jobs has said the iPhone won't accept third-party apps. The iPhone looks to be running on a Samsung provided ARM core processor. That means it's not running on an Intel (or PPC) core. That means it's not running OS X in any meaningful sense (Apple can brand toilet paper as running OS X if they like). Darwin, the BSD based operating system that underlies what Apple has previously been calling OS X, does not run on ARM processors. The Darwin / Apple Public Source licensing agreement says the source would have to be made available if it is modified and sold (paraphrased; read it yourself). A Cingular rep has said the iPhone version of the OS source will not be made available. It will be closed, like the iPod OS and not like Darwin. So if it ain't Darwin, it ain't OS X (in any meaningful way). An InfoWorld article on an FBR Research report breaks down iPhone component providers and lists Samsung as the chip maker for the main application / video cpu. So, that leaves the question... What OS is this phone really running? Not Linux or the source would need to be open."

      That means it's not running OS X in any meaningful sense (Apple can brand toilet paper as running OS X if they like).

      How does it mean it's not running OS X in any meaningful sense? I'd say having Cocoa/AppKit (and therefore an Objective-C runtime), Core Animation, and other OS X technologies constitutes being OS X.

      So if it ain't Darwin, it ain't OS X (in any meaningful way)

      Again, what is with this "meaningful" crap? Objective-C, Cocoa, AppKit, and the like are OS X. OS X is the NextStep-derived stuff running on top of Darwin. It can most certainly be OS X without Darwin. In fact, it might be Apple's first steps toward moving off of Mach sometime in the future.

        Agreed...

        The keynote very specifically listed:

        Syncing, Networking, Multi-tasking, Low power, Security, Video, Cocoa, Core Animation, Graphics, and Audio...

        Some of the above is very "duh", but having Cocoa, and Core Animation are two things that I would consider to be part of OS X... so even if the thing doesn't run the Darwin kernel, if it's compatible at the application layer I'd consider it OS X enough. ;)

        Seems like people are splitting hairs here...

          Back when Darwin was part of OPENSTEP, it ran on:
          1. i486
          2. SPARC
          3. Motorola 68K
          4. PA-RISC
          After Apple bought it, they ported it to PowerPC. It hardly seems a strech to expect that they could port it to a fifth platform, especially one they designed themselves. And, as you mentioned, they have no more obligation to release the source than they did for OPENSTEP; it's their code, they can do with it what they wish. The license agreement is a binding agreement between the copyright holders and people who want the code, not between the copyright holder and themselves.

        I'm not sure why you bothered to reply to this article; it's so utterly wrong in so many ways. First of all, Apple holds the copyright to Darwin and can use it however they want. Just because they license it to YOU under a license that requires YOU to share code you modify, Apple is not bound by that license. Secondly, it would be silly for Apple NOT to leverage some of the Mac OS, but it would be just as silly for them to port the entire desktop OS. I think of this as about the same as saying the XBox OS is Windows 2000. It shares many APIs, it's branched from the same codebase, but it's targeted and maintained for a completely different goal.

      Looks like it really is a scaled-down version of Mac OS X. From Macworld Expo:

      The iPhone is running an optimised but full version of OS X that weighs in at "considerably less" than half a GB, according to Apple vice president of worldwide iPod marketing Greg Joswiak.

      Joswiak confirmed that the operating system sits in the flash memory of the device and that Apple will "provide updates to the operating system like we do today."

      Joswiak claimed that the reduced size of the operating system was a result of expertise of the team at Apple, rather than cutting out functionality or removing core technologies. "Remember that OS X on a Mac features a lot of applications that we don't have to ship on the iPhone," he added.

        It's pretty easy to figure out what they probably did: a port of XNU sitting under the most/all the higher level frameworks, and little of the BSD layer except the APIs. And like Joswiak said, thy can cut out a LOT of stuff without crippling the OS or APIs. A sizable chunk of /System and /System/Library can be cut out because it contains support for things not needed on a phone/ipod/internet device, then of course pretty much all of /Applications and that leaves you with a slim, but real, OS X.

    I think you are confusing OSX with Mac OSX. Mac OSX is the OS that Apple sell and put on their computers. At no point in the Keynote or after has anyone said that the iPhone runs Mac OSX. They have simply said that it runs OSX. To my mind this means that it is running a subset of Mac OSX. At the very least the iPhone OSX appears to be missing Carbon (no loss to me), the Finder and other "built in" apps and quite possibly Quicktime. Whilst Steve said it had Cocoa that normally just refferrs to the main Kits: Foundation and the App Kit. This does not include PDFKit, QTKit and so on.

    Whether is's based off Darwin or not is hard to say. At a certain level that does not matter. What would matter if Apple decide to open up to third part developers is the APIs that are available. There may be a small subset that want POSIX on their phone but for actual application development Cocoa with some custom PhoneKit is probably all that is important.

What OS is this phone really running? Not Linux or the source would need to be open."

    We know that Windows CE does not use the NT kernel. This means that it is not using the same kernel as Windows XP and Windows Server. That means that WIndows CE is not Windows in any any meaningful sense. (Microsoft could brand toilet paper as running Windows if they like.) The NT kernel, the Mach-like microkernel that underlies what Microsoft has been calling Windows since the end of DOS, does not run on mobile phones or PocketPCs. The Microsoft Windows EULA is totally proprietary, and its source is carefully controlled. A Verizon Wireless rep said he had no idea what I was talking about. The WinCE source code is closed, like that of the Zune or XBox, and not like Linux. Now, Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor.

    At it's lowest level, the Mac OS X kernel (XNU) is based on Mach 3.0 with a BSD "personality" to provide (mostly) POSIX kernel APIs and helpful functionality such as a network stack. The OS X userland is mostly ported from FreeBSD and NetBSD. On top of that is Cocoa, Carbon, Java and all of the other APIs normally used for application development.

    As an interesting note is how Jobs described the OS the phone uses. He said "OS X." Normally Apple refers to their desktop operating system as "Mac OS X." That tells us a few things about what's really going on inside the phone.

    My educated would be: the phone does run the Mach part of XNU, likely runs at least parts of the BSD subsystem and the I/O Kit device driver interface. Apple has also said that the iPhone supports PDF. This leads me to guess that parts of WindowServer and CoreGraphics are there. The references to Widgets support this as well. Widgets also tell us something else: WebKit is available. Calling the browser Safari supports this.

    So, it's not the Mac OS X that runs on this laptop, but it would appear that enough of the existing OS X technology is there to call it OS X. Though, all of this is total speculation the product isn't on sale so it really can't be analyzed.

    Finely, I'm still not entirely sure the no third-party apps bit is a forever thing. We don't know anything but what they've said, but I'll wait until Apple's World Wide Developer Conference (which interestingly is usually just about the time the iPhone ships) before I'll pass judgement on that.

    A lot of people are claiming to know what an iPhone really is like inspite of not having seen one or even known of their existence before a couple of days ago.

    It may be a striped version of OSX but it obviously is a version of OSX since it has some very OSX features like Core Animation which doesn't even show until Leopard. Even things like Widgets are OSX. They've been working on the phone for years so I'd assume they adapted the OS to the chip they are using. Using even a notebook processor would be silly. The power requirements would limit you to one five minute phone call per charge.

    What really seems to be pissing everyone off is it's a computer under the hood and Apple isn't open sourcing it. Apple has always been big on protecting their hardware and I'm guessing that's why they aren't providing the code. It's meant to be a phone at this stage and they don't want to deal with all the hassles of people screwing up their phones trying to get Pong to run on it. Also that has to be the crown jewel for virus writers so why help them? I'm sure they'll open it up to development eventually but it's likely to be years and only when it starts crossing the line into becoming a full on portable computer. It's a staggering smart phone, deal with it.

It's a lot more common to run phones on ARM cores, but PPC can do it. A power PC core would make it much more likely that the iPhone is running on some variation of a Darwin based OS X. 2. Apple doesn't have to make any Darwin based operating system open if they don't want to. Their license restricts everyone else. So there was no material basis for my Suggestion that the iPhone isn't running OS X. It might not be, but my reasons were mostly wrong.
