> It is doubtful that a PPC system can boot an intel MacOS HD. One is RISC the other CISC. That's the point of fat binaries: they contain .text sections for several architectures. Even the installation DVD was a single one, for both platforms. Some more modern example of the same concept: Terminal: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e] Terminal (for architecture x86_64): Mach-O 64-bit executable x86_64 Terminal (for architecture arm64e): Mach-O 64-bit executable arm64e
