Mac OS X Lion build 11A419

Mac OS X Lion build 11A419 is the official Developer Preview 2 build of Mac OS X Lion. 32-bit CPU support has been dropped in this build, While the Mach kernel is i386-compatible, components like the Finder and WindowServer are only x86_64-compatible. As a result, this is the first build since Mac OS X Tiger build 8S2167 to support only a single processor architecture, and would remain that way until macOS Big Sur.
