Workaround Restores Mac OS X 10.6.2 Compatibility With Intel Atom Processors

InsanelyMac reports that a member of its forums has created a workaround allowing users who have modified their Intel Atom-based netbooks into "Hackintoshes" in order to run Mac OS X to upgrade to OS X 10.6.2. The 10.6.2 update had specifically disabled native compatibility with those processors.

The changes Apple made to the latest mach_kernel removes support for this processor, leaving updated netbooks in a useless state. Fortunately, insanelymac user "teateam" patched the new kernel just two days after Apple rolled out the update. The original post can be found here. Many users are reporting success with this patch, so if your an Atom user looking to update to 10.6.2, give it a try, and let's not forget to give "teateam" a round of applause for saving all our hackintosh netbooks!

The reasons for Apple's disabling of Atom compatibility in 10.6.2 remains unknown, although some of speculated that the company is attempting to make it more difficult for users to create their own netbook Macs ahead of a possible tablet launch next year.

Don't Hackintoshers know where to go to find this information?

Don't care much one way or t'other about this. I just want the mysterious :apple: iTablet to come out ASAP. :p

They must've disabled support in the kernel in some pretty simple and obvious way if it could be hacked in two days.

If it _was_ intentional, I'm a little disappointed in them. ;)

If Apple does put out a tablet device early next year, it won't be an Atom, but it won't be anything like a Dell Mini-V anyway.

If Apple does get around to make a netbook style computer will they have missed this idea as people will then move on to other non-Apple ideas.

The patch did a binary edit to change 3 bytes in the kernel (see machine translation of post).

I'd guess that there's a table of allowed CPU ID codes, and the patch just changed one entry for a similar CPU (he used Core Solo) to have the codes for the Atom.

The theory that Apple's streamlining the OS by removing support for Atom is pretty much a dead one now. Apple removed a table entry.

...then why bother disabling the netbook hacks? Seems like a different target audience.

Its clear now that Apple had something Atom-related in mind and now don't so dropped the CPU id as superfluous. Nothing sinister, no target audience in mind.

If you want hackintosh to live on without Apple disabling it every other update, STOP POSTING INSTRUCTIONS on a site that probably half of Apple employees follow for entertainment!

Thing is, there's a big difference between taking out a CPU id to make sure the OS won't start and simply not supporting the atom in the OS. Apple has done the former as the Atom ran Leopard / Snow Leopard anyway. There was no special functionality code written by apple so it would run (Leopard predates the Atom processor).

So it's not like Apple are not supporting the Atom, they've actually intentionally made sure it won't start which is not right.
