Mac OS X Snow Leopard build 10A222

Mac OS X Snow Leopard build 10A222 is an ADC (Apple Dev Center) developer preview build of Mac OS X Snow Leopard. It is the first build of OS X that is unable to boot completely on Macs with the PowerPC CPU architecture. While BootX is still included and the Mach kernel is PPC-compatible, components like the Finder and WindowServer are only Intel-compatible, and PPC kexts have been removed. PPC-compatible components would continue to be left over up through the RTM release.

Changes

 * Rosetta is now listed as an optional installation in the installer.

Bugs and quirks

 * You cannot launch the installer from build 10A190, you must boot into the partition the install DVD is located on.
 * Upgrade installs may not work.
