Are there 32bit-only 10.5 systems? Can it even be installed on a Mac
that lacks a 64bit CPU?
It's a bit difficult to find accurate information. I ask because Qt
supports down to OS X 10.5. 10.4 is not supported (at least not with
Cocoa, and Carbon was deprecated by Qt I think). If 10.5 can't be
installed on 32bit Macs, then it makes sense to build for 64bit.
The same goes for the PowerPC 10.5 Macs though. Can 10.5 be installed
on 32bit-only PPCs?
