Netbook owners waiting for a hack that lets them run Mac OS X 10.6.2 can breath a sigh of relief now that an industrious coder has come up with a patch. Apple's most recent Snow Leopard update isn't compatible with the Intel Atom processors used in many netbook computers, which left many in the "hackintosh" community wondering if they would be able to move beyond Mac OS X 10.6.1 on their third party PCs.
One forum member at the InsanelyMac Web site posted a patch that lets users install the Mac OS X 10.6.2 update on their netbook PCs. After about a week of testing, intrepid hackers have been reporting that the hack seems to be working fine.
Apple doesn't support Mac OS X running on anything other than its own Mac hardware. That doesn't, however, stop people from finding ways to install Snow Leopard on PCs from other companies, and netbook computers are especially popular.
Since Apple's OS updates seem to break on netbook computers, it's a good idea to wait for updated patches from the hackintosh community before updating.

The hackintoshers accomplish this by using the Darwin kernel source code, which is available under the Apple Public Source License. The Darwin kernel is essentially the UNIX underpinnings of Mac OS X. And it is perfectly legal and legitimate to modify the kernel and make it available in binary form, so long as the developer offers the source code changes to recipients or makes them public. It is also perfectly legal and in the spirit of the APSL to run the Darwin kernel on non-Apple hardware and even ship products containing the original or modified Darwin kernel.
In the particular case of 10.6.2, patch developers say that Apple is doing finer differentiation of processor families in order to optimize some things for some of the Intel processors that are in supported Macs.
Apple gets a great deal of benefit from this arrangement. For starters, many of the security fixes you see streaming out of Apple are possible because outside parties can examine the source code, identify potential flaws or (better) implement actual exploits, and submit them back to Apple. Assuming that the hackintoshers are paying for each copy of Mac OS X they install, the part of the EULA they are violating is the “only install on Apple hardware” part.
