Later versions of OS X support both 32-bit and 64-bit Intel and PowerPC machines, but they're starting to set lower bounds on what it will run on - it won't install on my 2003 model G4 eMac, for instance. I expect that by the time OS X gets write support for ZFS, PowerPC will be history. I also suspect that Apple see ZFS as a mostly server-side feature, which reduces the importance of 32-bit machines even further. (Going off on a tangent, I was very amused by the self-styled pundits' amazement at the Intel Mac announcement. "Gee, we never saw that one coming!" I mean, Darwin had only had i386 and "fat binary" support for five years at that point.) DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
