Sevenmac Magazin got themselves some screenshots of Apple's new OS X update, Snow Leopard, and it looks like apps with 32-bit modules will need to run in 32-bit mode even if they are 64-bit.
We know that Snow Leopard isn't going to be any kind of massive overhaul, but more of a refinement of the existing OS. It's aiming for stability, speed, and power management.
All the other screenshots that Sevenmac have just look to be proving that they actually have a working version of Snow Leopard. This one, though, is definitely weird. You have to restart the preference app in 32-bit mode in order to access the Network preference pane? Is it because this developer version only has the 32-bit version of the Network PP done? Is that going to be a recurring issue, that 64-bit apps that have to somehow work with 32-bit code needs to start/restart in compatibility mode? It would be super annoying if the OS doesn't handle it transparently, so this has us scratching our heads.
It is, though, probably a side-effect of Snow Leopard's tighter 64-bit compatibility. For more on that, and why 64-bit is going to make 10.6 cool, head over here to Giz Explains.
