Mac OS X 10.6.2 may fix a laundry list of bugs and headaches for most users, but it doesn't run on Atom processors so "hackintosh" netbook owners are out of luck. Prior to the release of the Mac OS X 10.6.2 update, resourceful netbook owners have been able to hack Snow Leopard to run on their Intel Atom-based computers.
Internet forums and blogs began confirming rumors that the Atom chips in their netbooks wouldn't run Mac OS X 10.6.2 shortly after the update was released. One commenter on the the MyDellMini forum commented "So, I can tell you 10.6.2 DOES NOT WORK with the Mini10v. OSX tries to start, but it hangs before you can see the apple and system ist trying to boot again... you are in a loop."
Stell's Blog noted "The netbook forums are now blowing up with problems of 10.6.2 instant rebooting their Atom based netbooks. My sources tell me that everytime a netbook user installs 10.6.2 an Apple employee gets their wings."
Despite the disappointment hacked netbook owners are experiencing, Snow Leopard was designed to run on Apple-specific hardware. Since netbooks like the Dell Mini10v aren't actually Macs, Apple doesn't code Snow Leopard to include compatibility for those devices.
The ability to run Snow Leopard on Atom-based PCs was likely a little more than a stroke of luck, and losing Atom support may well be a side effect of bug fixes and code changes for the processors Apple officially supports in the Mac Pro, iMac, Mac mini, and MacBook lineup.
Considering how resourceful the hacker community is, however, it's likely that someone will figure out how to run Mac OS X 10.6.2 on their netbook soon.
