Has anyone successfully partitioned 10.5 or 10.6 OS on to a 64-bit machine made for 10.7 and up? If so, how's the reliability?

Thanks in advance.

If the computer came with Lion or Mountain Lion doubtful Leopard or Snow Leopard will run on it. As a rule of thumbs there is no going back to an OS released prior to the manufacture of the computer.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

There are no drivers for the newer systems on the older versions. Typically they will refuse to even install.

I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.

@louishen...I was considering workarounds to first move my loaded Powerbook to an Intel Mac through Rosetta (not supported after OS 10.6.8), and partitioning that onto a 64-bit system. Too iffy though, or plain impossible.
