If you’ve installed OS X onto laptop with an Intel Atom processor, do not update your version of Snow Leopard until further notice. Rumor has it that Apple has removed Atom support from 10.6.2. This means your Hackintosh will fail unless you mess around with the kernel.
Here are Atom users future options…
A) Stay with Leopard 10.5.8 (10.5.9 might have the same effect as 10.6.2)
B) Stay with Snow Leopard 10.6.1
C) Upgrade to 10.6.2 and use either the stock 10.0.0 kernel or use modded Snow kernels
The thinking is either that Apple is trying to stamp out Hackintoshes wholesale or they’re preparing a new update for an Atom-powered device down the line.
