Mac OS X 10.4.3 (intel) cracked.
According to various sources who've played with the build, you can again make OS X run on any newer PC
(your mileage may vary...). The interesting thing about it is that it was previously believed that since the 10.4.1 build which was on Apple's developer kit when it shipped, Apple had tightened the lock. However, it seems that hacker "Maxxuss" has applied the very same technology for the latest build as was used on the original 10.4.1 build.
Unless Apple is merely playing with the hackers - rumours are that Apple's actual
consumer hardware will be quite a bit different, and so would the operating system's locking code - it seems like Apple will
have an OS piracy problem...
