Apple’s Mac OS X Leopard is 64-bit done right, unlike Microsoft’s Windows Vista kludge

“Windows Vista will come in a multitude of flavours: six at the last count. And it’s said that all of these, bar the starter edition, will come with the added 64-bit support needed for modern CPUs – but the 64-bit versions will be completely different installable builds,” Dean Pullen reports for The Inquirer.

“The 64-bit installation will come with a 32-bit emulation layer called WOW (Window on Windows, and nothing to do with orcs and elves) which will, as you can probably guess, allow you to run your old 32-bit apps on your shiny new 64-bit Vista, via emulation. 32-bit hardware drivers will not work,” Pullen reports.

“There will be just one version of workstation-based Leopard (plus an accompanying server edition), and it will come with 64-bit and full non-emulated 32-bit support,” Pullen reports.

Pullen reports, “Starting with Xcode 2.4, the OSX Universal binary format has been extended to support 32-bit and 64-bit for both PPC and Intel processors inside the same file, giving OSX quad universal binaries. Users don’t have to choose between processor architectures nor 32-bit or 64-bit processors, either at the OS or application layers, it’s all abstracted away from them – as it should be.”

“Note that the non-emulated support in OSX is for applications and drivers. 32-bit programs on Vista 64 need to work on WOW emulation to run in Vista, and 32-bit drivers are a no-no. Lack of driver support is the main reason Windows XP x64 hasn’t been widely adopted, and why the Vista fudge will ensure hardware incompatibilities between the two Windows versions remain for sometime to come,” Pullen reports. “This is quite a boon for OSX, and one that should be highlighted frequently and often.”

  1. What’s interesting is that the original article is from the Inquirer. That site’s articles are 99% anti-Apple. So, anything vaguely positive is quite remarkable. Of course, the guy who is usually blasting Apple didn’t write the aforementioned article.

  2. I got iTunes.
    I got maybe 16 gigs of stuff in iTunes
    … yeah, ok almost 17 gigs of stuff in iTunes
    absolutely positively none of it, NONE of it is .m4a files.
    WTF is Sputnik talking about? Or is he just a stupid pimply assed teenager trying to sound like a computer geek.

    Pimple faced pimple assed teenager!

  3. Sputnik! Welcome back, slow day in Redmond or is it just your turn in the rotation? Love this one-
    If I need a robust 64 bit os for a particular advanced scientific operation, I can purchase a 64 bit Vista™…
    All anyone’s buying now is 64 bit Vaypa™. I’ll have Mac OS 10.5 before the big M$ has Windows 2001, uh -2004, wait -2005, ok -2007 available for sale.

    Give my regards to Macdude at lunch-

  4. Sputnik needs to add a disclaimer at the bottom of every post explaining to people that it’s an exercise in sarcasm. I guess all the replies he gets admonishing his post is half the fun for him, but to the rest of us it’s basically thread-jacking. I enjoy the wit and sarcasm but I hate how the thread then turns into an “I-hate-Sputnik”-fest for those who don’t know any better.

  5. “”Starting with Xcode 2.4, the OSX Universal binary format has been extended to support 32-bit and 64-bit for both PPC and Intel processors inside the same file, giving OSX quad universal binaries.”

    That should give Adobe enough time to make PhotoShop a quad universal binary by 2009! ” width=”19″ height=”19″ alt=”grin” style=”border:0;” />

  6. Hey, If I can get my next door neighbor to buy an imac, than any one of us can work constructively to get friends and family to switch.

    M$ R&D money spent on chairs? In that case, Balmer is not allowed to touch my Herman Miller office chair when I get it!
