    Can Yonah Cut It?

    By cyrana, in OSx86,

    AnandTech has a first look at "Yonah," Intel's successor to the “Dothan” Pentium M and the processor rumored to be Apple’s first choice for next year’s Intel Macs. It seems that the processor is a large improvement over its predecessor in many ways, although it’s still behind AMD’s dual core offerings in terms of power.
    From the article:
    Although we didn't consider it as such here today, Yonah will be quite impressive on notebooks. The thought of having such a cool running dual core processor in a notebook is honestly amazing, and the performance difference (especially for multitaskers) over what we have today will be significant.
    As a desktop contender, Yonah is a bit of a mixed bag. While its performance in content creation applications has definitely improved over the single core Dothan, it still falls behind the Athlon 64 X2 in a handful of areas. Intel still needs to improve their video encoding and gaming performance, but it looks like we may have to wait for Conroe and Merom for that.
    This is very interesting news, especially considering yesterday’s rumor about an Intel based Mac PVR. If Yonah truly is slated for that Mac Mini Media Mega Monstrosity (there are so many alliterative options…), will it have enough horsepower for the multimedia aspects of the machine?
    It seems clear that Yonah is a perfect fit for the other rumored Intel Macs in January, namely the iBook, Powerbook, iMac, PowerMac… oh, wait, we’ve heard rumors about all of them. If we believe the iBook/Powerbook story, it seems that Yonah will be the kind of low-watt, high-performance processor Steve talked about at WWDC 2005.
    It seems that time (well, actually, just a little over a month) will tell.
    Just a note that the 945G chipset (and similar variants) seems to be the intro platform, so if you're making a test box now, Dual Core+SSE3+NX+PAE+945(or similar) is your safest best). Also nice that the CPU seems as fast as a dual core 3.0GHz Pentium-D 830 even though it is just 2GHz, and is comparable to Athlon 64 models (most of the time, not in all tests). And, of course, it has the lowest power consumption of the CPUs tested, which makes it look nice for laptops (It IS a mobile CPU after all...)
    But I don't know how some of that media performance will impact the "Kaleidoscope" product...perhaps its more than enough for that function, but Merom and Conroe are going to be better for media.

    Think Secret is reporting that Apple’s first Intel-based Mac will be a Mac Mini built as a media center. From the article:
    Apple's Mac mini will be reborn as the digital hub centerpiece it was originally conceived to be, Think Secret sources have disclosed. The new Mac mini project, code-named Kaleidoscope, will feature an Intel processor and include both Front Row 2.0 and TiVo-like DVR functionality.
    The new Mac will supposedly be launched in January at the Macworld Expo. Steve Jobs is a man of vision, and it would appear that computing (and computer tech in general) is moving in the direction of entertainment - the smaller/prettier/easier, the better. Windows Vista will no longer have a separate Media Center edition, but wil instead have multimedia functions built into every distribution. It makes perfect sense for Apple to want to strike first in the home entertainment arena – I think it could lead to the capturing of a market that hasn’t largely been tapped commercially.
    If these reports are true, one must wonder if Apple can become the dominant force in living room computing. Is it possible that “Kaleidoscope” will become as ubiquitous as the iPod?

    We've received unconfirmed reports concerning a few interesting new toys under the hood of OSx86 10.4.3, including a vastly improved Rosetta and brand new ATI drivers - each far more complete than in previous builds.
    First, the Rosetta emulation platform in 10.4.3 build 8F1111A has been upgraded to feature full G4 support, including Altivec. This not only adds a new layer of compatibility to Rosetta, but also improved speed for Altivec-equipped applications. This upgrade is reportedly available as a small downloadable update to build 8F1111.
    Also, new ATI drivers available in 10.4.3 seem to offer much greater support for PC ATI graphics chipsets. Preliminary reports indicate that they may support most of the 9000 line, and parts of the X series, including mobile chipsets. Apparently NVIDIA systems have not been given this treatment. Is this discrepancy simply due to the pace of driver porting at Apple, or will ATI graphics hold a special place in the Mactel world?
    On a side note, the weekend brought a newly leaked copy of OSx86 10.4.3 build 8F1111, the most recent seed from Apple. This seed, with its universal binary of iTunes, is a newer version than the build which was recently cracked.

    Sources indicate that OSx86 10.4.3 – which, as reported in this space, contains increased hardware restrictions – has now been cracked in the same fashion as 10.4.1. It was initially thought that these restrictions would slow the progress of hackers, but it appears that they've done little to deter those tackling the challenge.
    There are many interesting aspects to this news. First, it appears that Apple’s security enhancements between releases simply were not effective. Also, not only has the hacker named Maxxuss been able to hack the kernel to run on non-Apple hardware, he’s also been able to make the OS available to those who don’t have the most cutting edge hardware available.
    While Apple has promised to lock their operating system to their hardware once its released, one must wonder what method they will use and if it will be stronger than the current TPM restrictions. While the TPM technology is itself virtually uncrackable, hackers have been able to fool the OS into thinking it doesn’t need the TPM authentication.
    Will Apple ever be able to create a truly hack-proof OS? Right now it seems the score is Apple: 2 (leaked) releases, Hackers: 2 releases. With Intel Macs likely on the way in January, it’s game point and Apple’s move.
    Stay tuned here for the latest news as it happens.

    As has been reported in several news outlets, Apple has filed for a patent which seems to be directly preparing the company for the upcoming Intel switch. Patent 20050246554 was filed by Apple for rights to what they call a "system and method for creating tamper-resistant code."
    According to the article:
    "Tamper-resistant software is software that is difficult to change, tamper with, and/or attack. Code obfuscation is one technique for achieving tamper-resistant software. Generally, the goal of code obfuscation is to make it difficult for attackers to determine what is happening in a block of code. If attackers use debuggers or emulators to trace instructions, code obfuscation can make the code difficult to understand or change."
    Also of note is the ability to select for the Macs to choose from one of the three operating systems: OS X, Linux, or Windows. This would seem to indicate that Apple is committed to earlier statements of supporting (but maybe not encouraging) multiple operating systems.
    Will the "tamper resistant code" be a part of Apple's mechanism for locking the OS to Apple hardware?

    For those holding out for an Intel Mac, don't spend too much this Christmas - multiple rumor sites report that insiders tell them to expect the first Mac based on Intel chips in January. Apparently, Apple wants to surprise the computing world with the new Macs ahead of schedule. This makes perfect sense, especially since the x86 version of the OS has now reached parity (for the most part) with its PowerPC predecessor.
    From AppleInsider:
    "Sources say at least one of the two aforementioned Intel Macs appears to be based around Intel's upcoming dual-core 'Yonah' mobile processor, which is expected to top-out at 2.16 GHz in its initial rev. However, further processor specifications remain largely unconfirmed at this time. [...]"
    "The analyst went on to say that Apple is likely to ship Intel chips inside consumer-oriented products -- like laptops -- first, because the company tends to include with those computers most of the software consumers initially need and want. "I see mostly benefit if applications like iLife are ready for Intel processors," Wilcox added. High-end applications not yet compiled natively for the first Intel Macs will continue to run seamlessly -- albeit slightly slower -- via Apple's integral Rosetta technology."

    Xcode 2.2 Final Released

    By hatoncat, in OSx86,

    Apple has released the final version of Xcode 2.2. This is the second release of Xcode to support Universal Binaries, and the first to lock out 10.4.1 Intel (the leaked/hacked release). Xcode 2.2 makes significant improvements to SEE opcodes and the Accelerate framework, as well as general Intel compatibility improvements.

    Many sources have reported that the latest build of Mac OS X 10.4.3 seeded to developers includes an Intel-compiled version of iTunes. Previously, iTunes was the only major non-system application to be PowerPC-only. It is now a Universal Binary but does have some ongoing known issues with it; Apple has cautioned developers of these issues as minor and will be resolved shortly.

    The Mozilla Foundation has established a page on their Wiki that has the latest Intel Mac builds for their most popular applications; Firefox, Tunderbird and Camino. They also announced full support for PowerPC and Intel builds, and upheld their comitment to supporting Jaguar and Panther versions on PowerPC via the lipo process; a tool designed to allow different methods of compiling applications.
    Lipo holds much potential for specialized Mac development, the lipo process will eventually be used to allow Mac developers to use Intel-released compilers for Intel code, while still using GCC3/GCC4 for PowerPC applications, thus giving each platform the best performance possible while still remaining a Universal Binary.

    Of an interesting note, Apple's Photo Booth, included with the new iMac, is the first consumer universal binary released by Apple. While Xcode is a universal binary since version 2.1, it is generally only targeted at developers. iMac owners have been reporting this news since the release of Mac OS X 10.4.3, which includes the ability to check what architectures are supported by an application in most info panels.
