.XPKU is Apple Mac OS X universal binary package file
The XPKU file extension is related to Apple Mac OS X computers. An *.xpku file contains universal binary package used for installation of applications to Apple Mac OS X operating system.
A universal binary is, in Apple parlance, an executable file or application bundle that runs natively on either PowerPC or x86 (Intel)-based Macintosh computers. It is an implementation of the concept more generally known as a "fat binary". The universal binary format was introduced at the 2005 Apple Worldwide Developers Conference as a means to ease the transition from the existing PowerPC architecture to systems based on Intel processors, which began shipping in 2006. Universal binaries typically include both PowerPC and x86 versions of a compiled application. The operating system detects a universal binary by its header, and executes the appropriate section for the architecture in use. This allows the application to run natively on any supported architecture, with no negative performance impact beyond an increase in the storage space taken up by the larger binary.
