Mac OS X Tiger build 8B1025 is a build of Mac OS X Tiger. This build is notable for being the first public demonstration of x86 Mac OS. It was later released on development kits for the transition to Intel processors that Apple was doing. This particular build has a BIOS-based bootloader known as Boot-132, which was used as the foundation of modern Hackintosh bootloaders. Apple did not switch to EFI for x86 until version 10.4.4.

The user interface remains completely unchanged from the PowerPC version of Tiger 10.4.1, however the operating system itself has been revamped underneath to support x86.
