Thanks Scott.

I follow what you are saying and understand how my MBP is in between bootable releases.

However, I believe Dan was claiming that 10.6.4 (an official minor release) may not be bootable on all Macs released (and supported - to exclude older Macs).

That sounded somewhat strange to me.  Is there precedence for this?

I THINK what is happening, is that your Mac and it's system build comes with specific support for your CPU. I don't think that support arrives via a 10.6.4 type update, although it MAY be in the combo updater (not sure there). So while the updater may be smart enough not to SQUASH your CPU support, it isn't setup to add it to everybody's OS (hence it won't do anything on your older system). It's probably a facet of Apple rushing to support CPUs, but not necessarily regression testing all that code against a plethora of existing environments.

My plan for now is to wait for 10.6.4 (hopefully soon) then update my old MBP and clone again to the new MBP. I assume this will work?

I would assume not, although def. use a combo updater, but I still worry that wouldn't work.
