Mac OS X Leopard developer features leaked

“Apple Computer’s recently previewed Mac OS X 10.5 Leopard has made quite a stir, not because of what was shown at the World Wide Developer Conference but of what was excluded from show, cited ‘Top Secret.’ However, the build released to attendees at the conference includes a huge number of ground-breaking changes to the underlying technology in Mac OS X and the APIs exposed to developers,’ AeroXperience (AeroXP), a Windows Vista Developers Community, reports.

AeroXP has received information detailing several of the API improvements to Leopard, including:

• Leopard will feature resolution-independent user interface and there are several functions to get the current scaling factor and apply it to pixel measurements. It is a good idea to use vector controls and buttons (PDF will work fine) or to have multiple sized resources, similar to Mac OS X icon design, so you can scale to the nearest size for the required resolution.

• Carbon, the set of APIs built upon Classic MacOS and used by most 3rd party high-profile Mac OS X applications, now allows Cocoa views to be embedded into the application. This could provide applications like Photoshop and Microsoft Office access to advanced functions previously only available to Cocoa applications.

• Time Machine has an API that allows developers to exclude unimportant files from a backup set which improves backup performance and reduces space needed for a backup.

• Core Image has been upgraded to allow access to RAW images directly

• Leopard also gives developers access to a “Latent Semantic Mapping” framework, which is the basis for spam protection in Mail. It allows you to analyze text and train the engine to restrict items with specific content(like spam e-mail for example).

• Quicktime 7.1 is included, and the underlying QTKit framework is greatly improved. There is improved correction for nonsquare pixels, use of the clean aperture which is the “user-displayable region of video that does not contain transition artifacts caused by the encoding process”, support for aperture mode dimensions, improved pitch and rate control for audio and a number of developer improvements, like QuickTime capture from sources like cameras and microphones, full screen recording or QuickTime stream recording. Live content from a capture can be broadcast as a stream over the network.

Mac OS X 10.5 Leopard to feature ‘resolution independence?’ – May 21, 2006

  1. “Native Windows without Windows” is a BAD idea, because it would be relatively trivial to create Windows viruses that will execute “natively” on the Mac. Viruses, after all, are self-contained, self-replicating APPLICATIONS.

    Just trying to anticipate just all the unintended scenarios resulting from “Windows without Windows” should give anyone nightmares.

  2. This news is certainly not the “Top Secret” features that Steve referred to in the keynote.

    What this is is the “under-the-hood” aspects of what we saw in the sneak preview, i.e. the “boring stuff.”

    Based on the comments so far, it seems Apple made the right decision not to talk about them in the keynote, but any developer worth squat will know how significant these changes are. Resolution indepdence is huge. RAW image support in Core Image is huge. I’m sure we will be getting more informed analysis as developers dig through their Leopard Sneak Peek discs and digest all the new stuff.

  3. Cubert,
    Yeah, I heard it.
    Also, spotlight right now allows the searching and starting of applications. I don’t know what new things they talked about in the keynote, because all the things they talked about are already available (except for searching the internet)

  4. Somebody Fix QuickTime’s streaming behavior. RealMedia’s Player kicks it’s ass on streaming content. Anybody who tried to watch the WWDC Keynote in the early hours after it was posted knows exactly what I mean. I have a very fast Cable connection and the stream was like something from M$ back in the day.

  5. Dukey, I wonder. At 0:54 in the keynote, His Steveness was demoing Voiceover, and compared the Tiger voice, the Vista voice, and the Leopard voice reading the same standard text. He didn’t fire up Vista, how did he get the Vista voice to run? Did he pull a Milli Vanilli and pre-record? Or were we treated to a quiet preview of the Red Box?

  6. More stuff from the article MDN didn’t list:

    “Complete 64-Bit support for Intel and PowerPC through all frameworks”

    “Automator includes a new user interface and allows things such as action recording, workflow variables and embedding workflows in other applications.” (yeahhh!)

    “A new Calendar Store framework allows developers access to calendar, event and task information from iCal to use in their applications or to add new events or tasks.”

    “A new control for creating matrices of views is available, NSGridView. This allows a grid to be created from any view in the system, including OpenGL or Web Views.”

    “Core Animation allows layers to be used as backing stores for a view, windows to use explicit animations when resizing (can be three dimensional, akin to the Time Machine view). Any view can now be put into fullscreen mode and a CoreImage transition effect can be used. Using Core Animation you can create anything including GPU-accelerated Front Row-style user interfaces without having to write OpenGL code. A Core Animation layer can include OpenGL content, Core Image and Core Video filter effects and Quartz/Cocoa drawing content, like views and windows.” (more eyecandy – yeahhh!)

    “Text engine improvements include a systemwide grammar checking facility, smart quote support, automatic link detection and support for copying and pasting multiple selections.” (multiple clipboards – yeahhh!)

    “”Sharing accounts” are possible, with users being restricted via an access control list (ACL) to certain applications or files. Developers can integrate with this by restricting access to a specific piece of content by connecting it to a sharing account. Sharing accounts have no home folder.”

    “An Image Kit is included, to allow a developer to easily create an application that can browse, view, crop, rotate and pick images, then apply Core Image filter effects through an interface. A slideshow interface is also open to developers, allowing any application to display a fullscreen slideshow of images.”

    “Leopard also gives developers access to a “Latent Semantic Mapping” framework, which is the basis for spam protection in Mail. It allows you to analyze text and train the engine to restrict items with specific content (like spam e-mail for example).” (I know it’s above, but makes me go “hmmmmmm”)

    “Mail stationery is open to developers, allowing any web designer to create fantastic-looking Mail templates, with defined areas for custom user content.”

    Now, people, tell me this is just a “crappy dot update” as people have been saying since Monday!

  7. “Native Windows without Windows” –New Type is right.

    I’d much rather see an easy way for Windows developers to port apps to OS X…I mean monkeys-f***ing-footballs-easy.

    X Code 3 perhaps?

    There are some pretty cool windows only apps out there in the world, especially in niche markets. But I dread the idea of giving any kind of beachhead, however small, to malware. Maybe Parallels w/ 3d support will be enough.

  8. Macromancer,

    You’re right, I don’t want it to happen.. Why would anyone develop for OSX if Windows versions of apps would work just fine on OSX? Do you really want all your applications looking like Windows apps? I don’t…

    Besides, MS would sue the shit out of Apple if they ever tried this. Apple would essentially be using Microsoft’s technology (the Windows API) and eliminating the need for Microsofts flagship product. Can you even comprehend the legal ramifications of this? Well, let me spell it out for you. This would go down as the largest unfair business practice lawsuit in history, years in courts… etc. etc.. And trust me, ultimately, MS would win.

    Besides, Phillip Schiller clearly said “Absolutly not, dual-boot is our solution.”

    So yeah, keep dreaming… It will never happen.

  9. Apple’s strategy seems to be to drive OS X technologies so far ahead of the competition, that Mac OS X will become the platform of choice for developers, for consumers, and even for enterprise users.

    Apple making moves with open sourcing the Calendar server is just the first step in displacing the whole Outlook/Exchange beast that literally keeps companies suckling on Microsoft’s teat. The Linux community has failed spectacularly with trying to produce an alternative to Outlook/Exchange, but it looks like Apple is now making serious movements in that direction.

    Exactly, Apple is making it irresistable for developers not to develop for OSX. This whole Windows apps without Windows nonsense would do the exact opposite. I do not even worry, because as I said, legally it can not happen. I just wish people on these boards would think logically and realize this.

    Apple wants developers to develop OSX apps, not Windows apps.

  11. “A new Calendar Store framework allows developers access to calendar, event and task information from iCal to use in their applications or to add new events or tasks.”

    How cool would it be to select and right-click some text in a document, email, or on a web page that includes date and/or place info and add it to iCal as a task or To-Do?

  12. “Exactly, Apple is making it irresistable for developers not to develop for OSX.”

    On that note, I think it also explains Apple’s thinking behind the current ad campaign. The “I’m a Mac” and “I’m a PC” is intended to be antagonistic. Why? Because it gets Apple talked about. Try explaining the wonders of Spotlight to the average user – I suspect that eyes will glaze over more often than not, even if said person will find Spotlight useful once they learn how to use it.

    The ad campaign is designed to be antagonistic to a degree because it gets everyone talking about Apple and the Mac. Mostly, it seems to get Windows fanboys all huffing, puffing and in a red-faced tizzy, but ever seen a cat play with a mouse before a kill?

    Ever seen a champion boxer make seemingly ineffectual jabs here and there, occasionally allowing his opponent to land harmless body blows? What happens? The opponent begins to lose his cool and as he gets more desperate and enraged, begins to make mistakes, until finally, WHAM! one well-placed knockout punch ends the fight.

    Seems like to me that Apple is setting up Leopard to be that knockout punch. Time will tell, of course, but the next few months should be very interesting.

  13. i keep reading that OSX won’t get a lot of traction in ‘business’ because they don’t ‘support’ ‘business’ very well. I don’t know what that means. Networking? Reading files off a server? Sharing well with others? Whatever those things are, i’d like Apple to give more reasons for big companies to buy Mac.

  14. “I keep reading that OSX won’t get a lot of traction in ‘business’ because they don’t ‘support’ ‘business’ very well.”

    These comments refer to their unresponsive (and sometimes arrogant) attitude to corporate or educational customers. I know because a friend of mine runs IT for a school here in Philadelphia. He hates dealing with Apple because of this and is switching everything over to PC’s (unfortunately). He’s a reverse switcher.

  15. There is improved correction for nonsquare pixels

    That’s interesting.

    Last time I saw non-square pixels were the rectangular ones on the Apple IIGS twenty years go.

    Apparently they’re present on other platforms?

    Makes it kind of a pain to rotate images… ” width=”19″ height=”19″ alt=”grin” style=”border:0;” />

  16. The only thing Mac OS X doesn’t support for large businesses is ActiveX controls. My floundering mega-corp is chok-full of Windows-embedded network apps. They could easily be rewritten to support Macs.

    Aside from that, I dn’t think there’s a limitation beyond education.

    Come on, surely you know how big business works.

    It’s Ok to spend countless dollars & endless hours fiddle-fsking around making Windows work, but God help you in asking for ANY resources to port anything to Mac.

    And big companies wonder why they flounder. The idea of a small lean company running Mac OS is almost enough to make one an entrepreneur. ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

    This is an easy one…

    What they mean is that OS X doesn’t support legions of IT professionals. I remember someone on here (an IT guy) once explaining that he would allow people at his job to use a Mac only if they agreed to do their own tech support. Of course, anyone who was familiar with a Mac agreed readily.

    The people who buy computer systems can only work with information they’re given. The people who make the recommendations want job security, that means Windows and all its (job securing) problems.

    Now watch, some IT guy will come up with all kinds of reasons (stuff many of us have never heard of) and try to justify Windows. Well, I use XME at work (some kind of XP Pro) and it sucks.

    At work (unfortunately) I’m stuck with Windows XP Pro on a Dell (something-or-other, it’s a little black box) and the computer guy who came when we upgraded to these sad little crap-boxes told me the company pays something like $2200 a year for each one (leased). He said the price includes parts if they break, but not labor since the company employs so many computer guys.

    Everyone hates them and everyone is now starting to see that I’ve been right in telling them that every time the company “upgrades”, the machines get slower and less reliable.

    At home, on my dime and my time, only a Mac will do. My iMac (iSight) is the finest home computer available at any price. Walt Mossberg said so.

  19. I doubt these are the “top secret” features that Steve was alluding to.

    The average consumer wouldn’t even understand any of this.

    I’m betting that the only builds with the “top secret” features are those that are internal only.

  20. TheConfuzed1, you’re almost certainly right.

    What this post refers to are the guts of the Developer preview. It’s the non-obvious stuff that hack writers like Thurott overlook because, well, they’re hacks who lack the ability to actually investigate and disseminate data.

    It’s amazing how much disinformation is out there. People are already spreading this baseless idea that Time Machine = System Restore, and they’ve been doing it because they haven’t seen Time Machine nor the guts of Time Machine and basing their disinformation on assumptions.

    We need more detail stuff like this to make it clear Leopard is, in its earliest iteration, a huge change from top to bottom. It’s kinda sad that the very people who always complain about Apple’s “eye candy” are so easily fooled by surface appearances.

    The important point? Leopard is gonna be a killer cat by looking at the developer preview, even if its mostly camaflaged in the glow of the keynote.

  21. I agree that these things are not the “top secret stuff”. These were easily found by looking into Leopard’s API’s. The top secret stuff will be consumer oriented and not entirely necessary for developers to know too far in advance (ie. Finder improvements, better Spotlight GUI, improved Front Row, and maybe a delayed “one more thing”).

  22. I’m sure some of this IS among the “top secret stuff” they decided not to tell us about. Partly because they didn’t want Redmond to even think about including it, but mostly because, to quote clydeuhhh, okay <eyes glaze over>
    Half that stuff will make your Leopard experience so much ‘better’, but you’ll never have a clue as to how or why – even if they tell you. So … why bother telling you! When they announce Leopard has “200 new features”, you really don’t want to have more than half of them mentioned, much less described to you.
    They mentioned Time Machine because it’s flashy and would be hard to copy. They mention Dash Code because Vista already has that ‘set’ and, though it sounds great, it means little. Spaces is already out there – by 3rd parties. iChat is already out there for both – more 3rd parties. The only real news was how great it looks and feels and that they brought it into the distribution. Forgot – Mail, their robust email client is still playing catch-up to MS’s less robust email client … we now get pretty pictures and linking with iCal (etc) so SOHO users have one less excuse not to switch.

  23. > “Native Windows without Windows” is a BAD idea, because it would be relatively trivial
    > to create Windows viruses that will execute “natively” on the Mac.

    No, that’s not true. Windows has virus problems because the basic design is insecure. Applications have unrestricted access to the Windows core. You could quite easily run a Windows app in a restricted environment that would prevent any security holes in the app from damaging the OS X core.

    > Besides, MS would sue the shit out of Apple if they ever tried this.

    You ever heard of WINE? You can already run Windows apps without needing windows on a varity of UNIXes, OS X included. The only thing holding it back from perfection is lack of financial investment. See http://www.winehq.com/

    Apple could make Windows apps run natively in OS X but I don’t think they would want to. It would be a lot of trouble. Every time MS changes their API Apple would have to do the same. Witness the history of MS Office document format changes and how competing office products have had problems importing and exporting every time MS changed the format.

    More importantly I think Apple wants people to run their Windows apps on OS X alongside Apple equivalent products and discover that the Apple apps are better.

  24. What is the big deal if developers make apps for Mac or Windows, who cares? It is not like Apple will miss any cash income from a 3rd party vendor writing an app for Windows only. It only drives the point home about how much more compatible Apple is than Windows. An application is an application, ported, native or whatever lingo you want to throw at it. you still buy it regardless. No one benfits except for the author. If anything, it makes the applications more compatible from platform to platform.
