It is not legal to install MAC OSX on any hardware other than Apple-branded computers.
"If you install the software without a license from the copyright holder, you would be infringing on their copyright. Copyright infringement, legally, is not a crime, but rather a tort. A tort is an infringement of a right that leads to a legal liability. It's generally up to the copyright holder to file an infringement claim against the infringer.

I didn't say it was a breach of the criminal law, I said it was illegal which it clearly is.
