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.

Under 10.5 (we can’t discuss 10.6 on this list), there is only one kernel, which runs both 32-bit and 64-bit binaries. Although it actually contains a 64-bit version of the code under 10.5.8, I don't think it's ever actually booted as a 64-bit kernel outside of Apple’s internal development labs.

Stock 10.5.8 /mach_kernel, as shipped by Apple, only contains 2 architectures, x86 and ppc. It doesn't contain a x86_64 version. Apologies for the confusion. -- http://nevali.net _______________________________________________ Do not post admin requests to the list. They will be ignored.
