Rosetta basically translates the PPC code to x86 instructions that the Intel CPU can understand. Because of this problem in trying to suppport both PowerPC and Intel Macs, Apple allowed for creation of what is called a Univeral Binary in order to run the same app natively on either architecture (the app actually contains the code for both architectures).įor those OS X applications that don't have a Universal Binary and are only for PowerPC Macs, Apple has created a hardware emulation environment called Rosetta that is only installed on Intel Macs when OS X is installed (Leopard will be the first retail OS to sell that will install on both Intel and PPC Macs.currently there is no retail OS X version that will install on Intel, only PPC). ![]() Remember that the Intel chips and PowerPC chips are very different architectures, so they can't really understand the code that was written for the other architecture. WarCraft 3 as far as I know hasn't been updated to a Universal Binary (this is an app that can run natively on both PowerPC and Intel Macs). ![]() ![]() This has been discussed quite a lot here.
