I was just reading https://en.wikipedia.org/wiki/Data_General_RDOS#Antitrust_lawsuit which discusses Digidyne v. Data General:
When Data General introduced the Data General Nova, a company called Digidyne wanted to use its RDOS operating system on its own hardware clone. Data General refused to license their software and claimed their "bundling rights". […]. The precedent set by the lower courts eventually forced Data General to license the operating system because restricting the software to only Data General's hardware was an illegal tying arrangement.
The macOS EULA forbids installations of macOS on a "non-Apple-branded computer".
Am I missing something? - Why does this precedent not make hackint0shes legal?
