Mac OS X Tiger

Mac OS X Tiger User Interface

Mac OS X Tiger was released in October 2005. It introduced 64-bit support for Unix binaries (but not for the Mac OS X API) and was the first version of Mac OS X to support x86 (Intel) processors.

The original RTM build of Tiger (and several versions after) only supported PowerPC processors. Support for Intel processors was not added until build 8B1025. The Intel version of Tiger was only included with Mac hardware that required it, no boxed retail version of Tiger for Intel exists.

Mac OS X Tiger exists in both a Client and Server SKU, the Server SKU ships with additional applications that are part of Mac OS X Server, and requires activation.
