    So I went down to the local Apple store to have a gander at the new iMacs the other day. Think I'm going to get one. :D

    The weird thing is that I opened up Terminal on one and had look at mach_kernel in the / directory, expecting to see two kernel architectures, x86_64 and i386. Lo and behold, there was a third one; architecture ppc. What gives here? I thought SL was supposed to eliminate that. :confused:

    There is probably just enough there to allow Roseta to work.

    I wasn't aware that Rosetta needed any ppc kernel to work. Could be wrong, though. :confused:

    It's probably a placeholder for the table. Unless you know the internals, having something marked ppc doesn't prove much.

    Snow Leopard betas had PPC kernel in them as well.

    The only PPC stuff removed from SL is the ability to boot from PPC(i.e., Extensions), and the 64-bit PPC libraries. All of the other 32-bit PPC stuff has stayed in to support Rosetta.

    Clearly it's because the iTablet will use a PPC processor. :rolleyes:

    You never know...P.A. Semi did build them once, if they want to run Mac apps and don't feel the Atom would do the job...
