Apple Sets Oct. 24th Release For Mac OS X 10.3

dricci writes "Yahoo! has posted a press release from Apple, regarding the release date of the next major Mac OS X update, 10.3 ('Panther'). The update will be available 8:00 p.m. on October 24th at Apple Retail Stores and Authorized Resellers for $129.00 US (Family Pack for up to 5 users will be $199). Pretty much the same pricing structure they had for Jaguar. It looks like 'old world' Beige G3 support has been discontinued -- the update requires a Mac with built in USB."

    The only problem I find with the support is that the Wallstreet line PowerBooks, especially after adding a 500Mhz G4 upgrade was one of the best lines Apple ever made. I liked the Pismo line too, but the dual storage bay capability of the Wallstreet was a real plus. Floppy to floppy copy Expansion bay hard drive to floppy copy, or Zip and SuperDisk transfer was a real plus when I had to copy files for a client. I also upgraded my drive to DVD/CDRW combo drive.

    That said, 10.3 is the release of Panther you have been waiting for. Dramatic increases in speed and launch times - and I just have an older prelease from WWDC.

      Each version of OS X gets faster because, among other things, Apple has been optimizing.

      For example, in Panther, the Type 1 rasterizer had a lot of time spent on it, to the point where rasterization alone saw a huge improvement in performance (10.3's rasterization is almost twice as fast as 10.2).

      Of course that doesn't mean text draws *twice* as fast as there are many other factors involved in getting text on the screen. But it does mean that text draws faster in 10.3 than 10.2.

      Another example. Cocoa. Cocoa's invalidation model was really piss-poor. Often waaay more of a window would get repainted than was truly necessary. 10.3 greatly improves so any Cocoa-based app with many views will be much faster and more responsive.

      Another example. Carbon and and its controls. Rather than have all the controls rasterized in QD which in turn had low-level transformations to CG, eveything is now done directly with CG primitives. For example, the animating progress bar in 10.3 uses 1/10th the cycles as compared to 10.2.

      Yes: the OS is fundamentally 32-bits, but the kernel and key parts (math libs etc) are 64-bits under a G5, making it faster. This design decision allows running 32-bit apps seamlessly alongside 64-bit apps.

      Ie, does it allow applications to address more than 32 bits (4GB) of RAM? What's sizeof(void *)?

      Heres the rundown, from an Apple response in SCITECH:


      Hi all,

      There seems to be a bit of confusion on this topic. The short answer is
      The PowerPC G5 processor is fully 64-bit Mac OS X supports many, but not all, services using 64-bit integers.
      Currently, sizeof(void *) == 4

      I realize that some people take a rigid position that 64-bit computing = 64-bit OS = sizeof(void *) == 8. Which may be understandable given their problem space, but reality - especially when dealing with mass-market personal computers, not speciality workstations - is a bit more complicated, and different people benefit from Mac OS X's level of 64-bit support in different ways.

      Sincerely,
      Ernest Prabhakar

      Apple

      Mac OS X Jaguar (10.2.7 and later) features a redesigned kernel and updated system software math libraries specifically for the 64-bit PowerPC G5 processor. The updated kernel delivers the most substantial benefits of 64-bit computing by breaking through the 4GB physical memory barrier enabling the kernel to use all the RAM that can be added to the new Power Mac G5 (currently 8GB).

      The key functions of the system math and vector libraries have been hand tuned to make maximum advantage of new and faster math functions that the 64-bit G5 is capable of. This is a great because unmodified applications that use the system math functions will get an automatic speed up when run on the G5. For example, the square root function is implemented as a software algorithm when run on a G3 or G4 but on a G5 when a square root calculation is requested the math library uses the super-fast hardware instruction that the G5 has.

      This approach brings the maximum benefit of 64-bit processing to the desktop personal computer market and does so with full native-speed compatibility with existing 32-bit applications. Because the PowerPC instruction set was designed initially with 64-bit instructions in mind, this transition is a smooth and simple one for our developers and customers.

      Apple has also supplied a new compiler, GCC version 3.3 which generates optimal code for the new G5 machine model. Importantly, this compiler produces code that executes efficiently on G5, G4 and G3 systems so a single Mac OS X application runs on each of our support processor architectures. This allows developers to build and qualify a single version of their applications for the 32-bit and 64-bit Mac systems.

      Mac OS X Panther takes the same approach to the G5 as Jaguar but will be able to optimized additional math functions based on feedback from the developer community.

Actual real-time rendering of outline fonts came in 13 years ago, with Adobe release of Adobe Type Manager, but it was still pretty crude and ugly, with no antialiasing. Apple introduced antialiased text in OS 8.5, about 5 years ago (Microsoft offered it in an upgrade to Windows 95). The idea of antialiasing is an old one, but it wasn't until the mid 90's that computers had enough power to do it to text in real-time at a respectable (albeit slow by modern standards) rate.

  21. Re:Why is USB required? by Kazymyr · · Score: 2, Informative

    No, it's just because all of the machines with built-in USB are NewWorld, and all the macs without built-in USB are OldWorld (including the beige G3s). Saying that it won't support macs without built-in USB is marketspeak for "we've dropped support for all OldWorld systems".

    Cancel your orders, and re-order. Then: "call 1-800-767-2775 and have the phone tree direct you to the Operator and ask for Customer Relations. Make it very clear that you would like your complaint to be Officially Logged and heard by Upper Management." That is from an Apple rep in a discussion forum. I called and they logged my complaint, with a followup request.

  23. MacOS X 10.3 really is that much faster by laird · · Score: 2, Informative

    Well, rendering text has been "realtime" for 30 years, because the sophistication of what rendering text means has grown in complexity to take advantage of faster CPU's. Sure, on a 1.77 MHz TRS-80 I could edit text (16 lines of 64 characters!), but all text was white on black, monospaced pre-defined characters (not a graphics display, no fonts much less bolding or italics), and word wrapping was a special command that you issued when you were done writing because the computer took several seconds per page to format. On my current Mac (733 MHz G4, fairly slow by today's standards) I'm driving a huge 24-bit deep bitmapped display, where everything displayed is rendered anti-aliased, then mapped onto a display where it's alpha blended. It doesn't allow me to write much faster (OK, saving to a hard drive is a lot faster than saving to cassette tape) but it's doing 400,000 times as much work in order to do realtime spell checking, text wrapping, line layout, proportional spacing, etc.

    And to bring it back to the question of whether applications spend any time executing OS calls, _all_ of that work is being done automagically by the operating system. In fact, I can build my own (simple) word processor using Cocoa in minutes, by snapping together prebuilt framework components that understand fonts, layout, etc., so there's almost no application level code at all.

    Well, I guess the question of whether the HTML rendering engine is "in the OS" is a philosophical one -- one could argue that only the lowest levels (kernel, filesystem, VM, drivers, etc.) are really the OS. Or you could say that all of the Cocoa and Carbon frameworks and below (including QuickTime, the HTML rendering engine, etc.) is in the OS, which I think is what any Mac developer would say, since that's all stuff provided by Apple that applications can use. Or you could say that "everything in the MacOS X box" is in the OS, which would include applications.

    That being said, when people say "MacOS X 10.3 is faster than 10.2" they're talking about the performance of the total system, not attempting to differentiate between the performance of the filesystem, drivers, GUI, frameworks, applications, etc., so the distinction you're trying to draw is not terribly relevant.

    So while I guess you might be right in saying that applications spend fairly little time executing time in the OS if you define the OS as only the kernel, I think I'll stick with my definition of OS: the total software system as provided by Apple. And pretty consistently for nearly 20 years now (I've been developing Mac app's a long time -- I used to use the Lisa Pascal cross-compiler) well written Mac app's typically spend over 90% of their time in OS calls. So when Apple tunes their code, it really does have a strong impact on overall application performance.
