The OS hasn't been qualified to work on your system in this configuration. I know of issues that can prevent booting if you force 32-bit binaries to be used on certain configs due to assumptions they make about their environment.

Hi list,

On a machine that supports 64-bit operation (MacBook4,1 in this case), is it possible to boot (or install) Snow Leopard to run wholly 32-bit?

I know kernel_task runs 32-bit by default, and individual apps can be set to do so (e.g. http://support.apple.com/kb/TS2827), but here I really mean *everything* -- launchd, Dock, Finder, the shell,...

I'm hoping the question is specific enough to spare me "Why would you want to do this?" Thanks for any pointers,

Francois Z.
