Perhaps the most historically significant aspect of Darwin 8.0.1 is its support for the x86 architecture. While Mac OS X Tiger for Intel would not be publicly released until 2006 (alongside the announcement of the Intel transition), the Darwin source code and accompanying binaries in early 2005 were already capable of running on standard PC hardware. This provided the hacking community with the early groundwork for what would eventually become the "OSx86" project.

The system requirements for Darwin 8.0.1 are:

The 8.0.1 version number aligns directly with the internal versioning of Mac OS X 10.4. Following the release of Mac OS X 10.3 "Panther" (Darwin 7.x), expectations were high for the Tiger kernel. The April 2005 ISO release was critical because it confirmed that Apple was serious about supporting both the existing PowerPC architecture and the upcoming transition to Intel processors.

Darwin 8.0.1 is a relatively old version of Darwin, released in April 2005. At that time, it was the foundation for Mac OS X 10.4 (Tiger), which was a significant release for Apple. This review provides an overview of the features, stability, and usability of Darwin 8.0.1.

In April 2005, Apple launched Mac OS X 10.4 Tiger, a release that brought major innovations like Spotlight and Dashboard to the desktop. Simultaneously, the open-source community received , which served as the engine under Tiger’s hood. This period was critical because it preceded Apple's public transition to Intel processors; Darwin 8.0.1 already contained the cross-platform foundations necessary to run on both PowerPC and Intel x86 hardware. Key Features and Technical Architecture

Darwin 8.0.1 is an important release that provides a stable, secure, and performant foundation for developers and users. The inclusion of security patches, stability and performance enhancements, and updated development tools make this release a significant milestone in the Darwin project. As an open-source operating system, Darwin 8.0.1 serves as a vital component of Apple's ecosystem, and its impact will be felt across various industries and applications.

The , released in April 2005, represents a significant milestone in the history of Apple’s open-source operating system foundation. It serves as the underlying core for Mac OS X 10.4 "Tiger," one of the most feature-rich and lauded operating system releases in Apple's history.
