OS Battle: which is the best? (OS X, Windows, Linux ...)

[Love]

I haven't followed the TPM issue/nonissue, but I would point out that if it is "against the law to install Mac OS on anything other than an official Apple machine" then it is not an Apple stipulation, but a matter of federal or state law. And I strongly doubt that the US government has made it illegal to install MacOS X on a non-Apple-specific hardware platform. Perhaps you meant that it's a stipulation in the end-user-license-agreement (EULA) for MacOS X?

Well, I think you are just being pedantic here. However you want to play around with the semantics, it is considered an EULA violation / copyright infringement (against the law) to install Mac OS on anything other than an official Apple machine.

Also, Apple machines are ubiquitous on a global scale, not just the United States. The United States government obviously does not have lawful jurisdiction over any other country, so your point falls there.

Yet you provide no proof. I at least had the courtesy to link to an article written by an Apple expert who wrote an entire book on OS X...

My apologies for not providing evidence.

Here is the FAQ section on the official "OSx86" website (LINK). In the section with the heading "Do I need Apple hardware to run Mac OS X?", it states: "Not anymore. Projects such as OSx86 have succeeded in allowing the Intel-based version of Mac OS X to run on non-Apple hardware largely by bypassing the TPM in software".

I think you have some misconceptions about "hardware". You could find a laptop that has identical internal components as the MacBook Pro in terms of the CPU, memory, GPU et cetera; the only real difference would be the presence of the TPM in the Intel based MacBook, which is exactly what Mac OS looks for during the boot process. If TPM is not present, Mac OS will not boot or install. Hackintosh / hackboot bypasses the search for the TPM.
