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? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
