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 had a BIOS-based bootloader known as Boot-132, which was used as the foundation of the modern Hackintosh movement. Apple did not switch to EFI for Intel-x86 until version 10.4.4.

Changes from PowerPC compile[edit | edit source]

The user interface remains completely unchanged from PowerPC compile of Tiger, however, the operating system itself has been revamped underneath to support Intel. These changes include:

Kexts[edit | edit source]

Kexts or Kernel extensions, let developers load code directly into the macOS kernel. By giving developers these kernel privileges, kexts can help those developers create better preforming applications. Kexts are also used for Drivers.
