No, no specify. Universal means that the .app is for OS X and *always* contains *both* ppc and x86 code. So it WILL run on either a powerpc or intel based Mac, under OS X. The app may still be restricted as to what version of OS X it requires because of the features it uses and/or the way the developer built it. (eg: The upcoming Firefox 3.6 is Universal and requires Tiger or better. The upcoming Firefox 3.7 is Universal but requires Leopard or better). Note that "Universal" is basically moot when it comes to Snow Leopard because SL only runs on x86-based Macs. >Carbon Apps can run on either Intel under OS X, or under either 9 or >OS X on PowerPC machines Carbon apps are powerpc based, but can run under OS 9 or OS X (again, with the same restrictions as above). If run on an intel-based Mac, then they automatically use the Rosetta ppc->x86 translator. There is no such thing as a Carbon Universal app - to be Universal, you must use Cocoa - the native code-base of OS X, instead of Carbon. Just to add some confusion... You can run a carbonized app in Classic (OS 9) within OS X. Kindof strange to want to do so, but it works. Apple dropped support for Classic (the OS 9 emulator) in Leopard, and never supported it at all on intel-based Macs, regardless of OS X version. Sheep Shaver restores (most of) that support on the intel-based Macs. - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
