The Mac OS has a market share of <10% so calling Apple a monopolist is absurd. I've been a Mac user since the market share was south of 2% and I've always believed that their will be an OPTIMAL market share figure and it's not 90+%.
Exactly. Any talk of "apple is a monopoly!" is completely ridiculous. Only offering software for their own hardware is perfectly legal and not "tying". Tying is only a problem when it's two unrelated products (and there's no question that a computer and its OS are related), or when it's being done by a company that has a monopoly, as happened in the MS case.
With such small market share, apple simply isn't in a position to do anything monopolistic or anti-competitive. Anything they do, consumers have the option of going with the other 90% of the population and just buying a PC instead.
The hardware isn't made by Apple any more, now it is made by Intel who also make the same hardware for Dell.
Do you really think Apple made G5 chips? Apple has NEVER made that much of the hardware, mostly just assembled stock parts. The difference with intel is that the parts are just more common. Apple makes the cases and the motherboards, same as they always have.
So, let's say that Joe's Burger Place decides to sue Burger King...
Food is a terrible analogy for this. You can't copyright a recipe like you can copyright software or patent hardware.
I think that you are mistaken and you can run the standard disk on a version with a BIOS, providing that the hardware is supported by the Kernel.
Nope, you can't install OSX on generic hardware without some sort of hacking.
