Additionally, Apple's unique Universal Binary specification packs both 32-bit and 64-bit code into each application, making Snow Leopard's 64-bit capable apps backwardly compatible with 32-bit Macs. Snow Leopard does not share this problem, because it has no problem running 64-bit apps using its 32-bit kernel. This sticky bit has kept 64-bit adoption on Windows very low despite the significant advantages related to making the move.

Windows XP/Vista/7 users also benefit from running 64-bit apps, but Windows can only run 64-bit apps using the 64-bit kernel provided with the 64-bit "edition." This prevents mainstream generic PC users from realizing the benefits of the move to 64-bits unless they are equipped to make the full jump, which requires lining up 64-bit kernel drivers for all their hardware. Moving to 64-bit apps on other processor families, such as PowerPC, does not yield the same boost, but rather only incurs additional overhead, one of the reasons Snow Leopard is Intel-only.

Snow Leopard's upgrade to 64-bit system apps provides an overall speed boost due to limitations in the original design of Intel's 32-bit chips the move to the new 64-bit 圆4 processor model, originally developed by AMD, solves these issues. Running the 64-bit kernel or not, the singular version of Snow Leopard always runs 64-bit apps when running on 64-bit hardware in contrast, no 32-bit editions of Windows can run 64-bit apps, even on 64-bit capable hardware.

What Snow Leopard does do is bring all Core2 Duo, 64-bit Macs (pretty much everything sold since 2007) up to speed with 64-bit system apps, from the Finder and Dock to iChat and Mail to background processes such as launchd and the system-wide spell checker. The response will identify the machine as either having 32-bit or 64-bit EFI. If you're wondering whether your Mac has a 64-bit EFI firmware, you can type the command "ioreg -l -p IODeviceTree | grep firmware-abi" into the Terminal. Users who want to run the new 64-bit kernel on late modeled Macs (pretty much anything released after early 2008) can do so by booting with the 6 and 4 keys held down.

This problem has helped repress the popularity of the 64-bit editions of Windows over the last several years, but won't hold up 64-bit Mac adoption because there is only one edition of Snow Leopard, one that runs on all Intel Macs and simply adjusts itself to the limitations of the given hardware. This prevents mainstream users from running into problems related to incompatible kernel extensions and device drivers (such as printer software), which aren't yet 64-bit.

While there are certain advantages with the move to a 64-bit kernel, including new security enhancements, the primary benefit of a 64-bit kernel is being able to directly work with significantly more than 4GB of RAM, something that most existing consumer Macs and generic PCs can't do anyway.įor this reason, Snow Leopard also defaults to running its 32-bit kernel even on consumer models with 64-bit EFI. However, running a 64-bit kernel on these machines is of limited benefit. The 64-bit edition of Windows XP or Vista will run on 64-bit Macs with 32-bit EFI via Boot Camp because Windows doesn't use EFI it still lives in the simpler world of BIOS. It's true, 64-bit Core2 Duo machines prior to 2008 still run Snow Leopard's 64-bit apps using a 32-bit kernel, because Apple's 64-bit kernel requires both a 64-bit processor (a Core2 Duo or better) and 64-bit EFI. It seems fashionable to describe Snow Leopard's new 64-bit kernel as a problem for Mac users with 32-bit EFI (the startup firmware that launches the operating system).

Here's the second in a series looking closer at some of Snow Leopard's well-known, but often misrepresented or misunderstood features. As jingle-pundits desperately try to denigrate Snow Leopard as a "Service Pack," Apple's new operating system reference release actually expands the reach of the Mac platform in several important and under-reported new directions.
