So I know "google is my friend" but I haven't gotten a straight answer on this. I've seen threads about cheap CPU upgrades for the 1,1. I've also read about the chameleon workaround for upgrading the OS to something more current. What I haven't seen is an answer to this: Can a CPU upgrade address the OS upgrade limitation of the 1,1 MacPro? In other words if I install a newer CPU in the 1,1 MacPro will that allow me to install something more recent than Lion?
