Hence, wanted to know whether there are different installation images available for 32-bit and 64-bit OS. On Wed, Aug 19, 2009 at 3:46 PM, rohan a<info1686@gmail.com> wrote:
Thanks for this.
However, why then are there 4 binary types : x86, x86_64, ppc32 and ppc64 when the kernel itself is a 32-bit.
Will it be able to take advantage of the other 32-bits ?

Hi All, Does Mac OS X 10.5 provide separate 32-bit and 64-bit kernels ?Or there is only one type of kernel supported.
What I mean is that like Windows has separate version x86, x86_64, IA is there something like this for Mac OS X 10.5 as well ?
If not are there only 2 version: Intel i386 and PowerPC ?
and does the same thing run on 32-bit and 64-bit hardware ?
Most (if not all) of the answers are in the 64 bit Transition Guide and in The Universal Binary programming Guide.
