How Encrypted Binaries Work In Mac OS X
An anonymous reader writes "By now we know that OS X uses encrypted binaries for some critical apps like Dock, Finder and LoginWindow. Amit Singh explains the implementation of this protection scheme which makes use of the AES crypto algorithm and a special memory pager in Mach. The so called Do Not Steal Mac OS X (DSMOS) kernel extension helps along the way by decrypting things for the special pager when apps get executed. A funny thing is that if you print the pointer at address 0xFFFF1600 in your own app you get as output Apple's karma poem for crackers! According to the article there are 8 protected binaries in OSX including Rosetta and Spotlight meta data demon. Interestingly Apple's window server is NOT one of those."
Actually they're up to about 6% marketshare in the USA, and I think about 8% in the EU. And as for relevance, Apple, like Google are figureheads. When Apple do something, the rest of the market take notice. Like Widgets in OS X 10.4.....after Apple released this, Microsoft weighed in with 'Gadgets' (Yes, I know widgets come from Konfabulator, but Apple made them famous, and after Apple did so, Yahoo! bought Konfabulator, something that wouldn't have happened without Apple copying it in Tiger). So what Apple do is important because you tend to find 6 months after Apple do something, everyone else does too. I wouldn't be at all surprised if Microsoft use the encrypted binary idea in Vista SP1 or whatever comes after Vista (too late to put in Vista). I also wouldn't be at all surprised if Microsoft totally screw it up.

The fundamental purpose of Copyright law is to allow a creator to control how their works are disseminated. Obviously, Apple wants you to buy their hardware if you want to run their software, and they're perfectly within their rights to do so.
Say Chevy offers Radiohead $1 Million to use one of their recordings in a stupid truck ad, and Radiohead refuses. By your logic, Chevy should then have the right to use the recording anyway, because since Radiohead refused to sell them the song they're not losing any money.
You may think it's right, but hundreds of years of copyright law would disagree.
ENDUT! HOCH HECH!
Say I'm a black man. I go into a store to buy some bread to feed my family. The shop keep says "that bread aint for sale". I say I have a moral right to take it. Irrefutable.
Nice strawman. Because we all know, any attempt to control my property is equivalent to trying to starve a poor black family.
Your razor blade argument is equally crap. Those blades belong to the store owner. I don't care what you thought, you have no moral or legal right to steal more blades or to force him to give them to you. End of story. Irrefutable.
If you don't like it, shop somewhere else.

OSX is denying the user one of the fundamental Freedoms.
Uh, it might be a "fundamental Freedom" if you had a "fundamental Right" of some sort to do as you wish with other people's IP. Unfortunately, you don't. A significant number of people make a good living for themselves and their families working for companies that, while being very understanding and supportive of the free software movement in its proper place, gain competitive advantage over their peers by employing the best intellectual talent to solve problems with technological solutions that if copied would eliminate any sort of advantage that company may have in solving a certain problem.

If you purchase a physical item, do you still think of it as the seller's property after you've paid for it and taken it home?
When I purchase a car, the car is my property. Honda is not trampling on my liberties by not giving me all the CAD files and whatnot that were used to make my car.
