> Apple had to create a 32-bit version of the OSX operating system for Intel’s x86 architecture before quickly phasing it out because Intel was late releasing its 64-bit Core 2 architecture designs.

I've read before that internally, OSX always had a working x86 port, to ensure the OS is actually portable should the need for a switch arise. Like it did in the past with older macos versions. So in that case they even got lucky because it was the very architecture they switched to.



Also, they didn't have a lot of 64-bit stuff in PowerPC land during the transition, software- and hardware-wise.
