|In the current developer build of 10.6.2, Apple appears to have changed around a lot of CPU related information. One of the effects of this is Apple killing off Intel’s Atom chip.
Among other things, Sleepenabler.KEXT is now ineffective and will need a new version. It is now suggested to run CPUPM with a proper DSDT.
Stellarola also notes that similar restrictions in Leopard 10.5.9 may disable the Atom, and so advises any pre-Snow Leopard hackintoshed Atom netbooks to stick with 10.5.8.
Who know’s how this will be implemented or how long it will take them to figure away round it. But hopefully this won’t end the use of Mac OS X on third-party hardware.
