Not seriously, unless you believe Apple is going to start working with cops to kick in doors and inspect homess for non-Apple branded hardware for unsanctioned OS installs.

Even if a judge agreed with Apple's EULA (unlikely, and unlikely to be tested), that's not really enforceable in any practical sense unless you're selling computers with MacOS preinstalled. Then it's a matter of commercial licensing and distribution which they do have an interest in protecting.

So you're saying it's fine to break the law of you don't get found out?

Most people think its ok to break the law if you won't get found out AND they don't think breaking the law presents any moral issue.

Ever noticed how people tend to drive at a speed that seems safe given conditions? Respect for ethics is a virtue respect for the law for its own sake is a disease.
