According to OS X Daily, Snow Leopard version 10.6.2 will end support for Intel's Atom processor. This is an unfortunate blow to Hackintosh users who run OS X on netbooks, which are largely Atom-based. Those users will have to stick with an older copy of the Mac operating system, such as 10.6.1 (the latest Snow Leopard version) or 10.5.8 (the current Leopard release), as it is assumed that 10.5.9 will also bring the same Atom incompatibilities.
The move would highlight Apple's ongoing attempt to prevent users from running Mac OS X on unpermitted hardware. Mac clone maker Psystar has seen the brunt of Cupertino's struggle, having been engaged in lengthy court battles over the selling of unauthorized systems with Mac OS X. In October, Psystar began selling a $50 software hack that allows users to install Snow Leopard on some Intel-based PCs.
OS X Daily further speculates that 10.6.2 may be an effort to cripple Atom-based Hackintosh systems in anticipation of the long-rumored Apple Tablet. No matter Cupertino's motive, here's a heads up: if you're running OS X on an Atom, it's probably best to avoid 10.6.2 until a workaround is available.
