Nope, still not working.
So the saga continues. While tinkering around with a developer build of the next version of Snow Leopard Mac OS X 10.6.2, modders found that netbooks running an Intel Atom processor were unable to boot Apple's latest OS version.
Of course, the only way for anyone to discover this change was if someone was trying to run Mac OS X on a PC-based netbook. Nevertheless, this lead to much speculation that Apple is actively trying to lock out the netbook hackintosh crowd.
Then word came that a newer build of 10.6.2 brought back Atom support, making the modding community feel good and safe again. Sadly, it turns out that newer build was a fake and that the very latest developer seed still doesn't have Atom support – at least not on known hackintosh configurations.
So for now, it seems that hackintosh netbook owners will be living in uncertainty.
