It's about 9 months Vista has been there officially and not a beep by WCG, yet for most it works, so why would another More Wow is Now OS X variation not work? Suggest you give it a whirl and tell and share. Sure it will be appreciated by the under represented platform users (on these fora).

There is a stable 64 bit version of BOINC for Windows and Linux. Charlie Fenton (the Mac developer) has said he'll release a 64 bit version when Leopard is released. I'd imagine it will have to go through a bit of alpha testing before it's released to the general public though.

The Berkeley download page will give you the 64 bit option is you're running a 64 bit OS.

Note that BOINC just does management. It's up to an individual project to offer 64 bit binaries for the science apps.

My Vista/Fedora (dual booting) host is 32 bit on both. There are folks running the 64 bit version of both Windows (XP and Vista) and Linux (pick your favorite distro).

This thread at BOINC Stats is the most up to date list I know of for projects that send either true 64 bit apps or 32 bit apps to hosts running a 64 bit BOINC.

African Climate @ Home seems to have a problem with the new Leopard OS for Mac. See http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=16774

Are all the other projects verifying correctly on Leopard?
