A hackintosh computer is a standard personal computer that runs Apple Mac OS X as opposed to Windows or Linux. Hackintosh computers are a violation of the Apple EULA, as it states that "OS X shouldn't be installed on non-Apple-branded computers (Macintosh computers).
However, there are grounds to believe that this condition is only there to deter companies from making such computers and selling them for a profit (as in Psystar Inc. in the United States, later sued in court by Apple), not really to deter individuals.
My question is: Is the EULA valid?
Is the EULA enforceable in Islam? (like, does it apply if I remove it from the operating system?). It says that you automatically agree to its terms by merely using the operating system. Isn't that an enforced contract?
The condition of the non-Apple-branded computer seems to be a monopoly over the operating system (I sold the product to you BUT you can only use it however we wish and ONLY on our computers). Is such monopoly halal?
The company has R&D centers in Israel. Does that make any difference (supporting Zionists by using a product which may or may not be developed in Israel vs. harming somebody who supports Zionists by abusing their product?)
Edit: EULAs are not enforceable in my country. Please check yours for such enforceability.
