what do you mean with userland. I am trying to boot with arch=X86_64 flag.

At this point my biggest problem is I am trying to run in 32 bit an application that I didn't use since I had 10.6.2 and neither in 10.6.3 nor 10.6.7 works.
It crashes with Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00000000537465a3.
the application is compressor (from apple)
Mi idea was to try to boot in 64 bit to see if compressor runs.
But with your comments, I suspect my confusion is deeper.

I would appreciate a brief conceptual explanation of what I can do.

Regards!
