Native Compatibility with 32-Bit Application Code On other platforms, switching to a 64-bit computer requires migrating to a 64-bit operating system (and purchasing 64-bit applications) or running a 32-bit operating system in a slow emulation mode. With the PowerPC G5, the transition to a 64-bit sys...
