re: #279 engineer dog

i think i heard that these days Apple computers have an Intel cpu. I know that for many years they used Motorola cpus when at the same time most other pcs, the ones that come loaded with a Windows OS, were using Intel cpus

now, all programs running on a computer, including the OS which is ultimately just another program, need to speak the language of the cpu, known as ‘machine’ language. Intel cpus and Motorola cpus use different machine languages, so to run an Apple OS on a “Windows machine”, that is, an Intel cpu machine, in the old days, required that the Apple OS be re-written in Intel machine language. If Apple is now using Intel chips, it becomes merely a matter of loading whatever OS you want on to your machine, usually using different partitions of the hard drive to manage different OS, and other programs that manage switching between OSs

i’m pretty sure this is all correct, but please check me for errors

You are correct. I am running 10.4.11, which is the last flavor of the Mac OS that can be run on the old RISC chips. Sad, but it seems that I will have to buy a Mac with Intel chips to upgrade my OS.

Piss.
