经过28年的等待，经典第一人称射击游戏《半条命》终于被移植到PowerPC架构的Mac OS 9系统上[1]。这一移植工作由GitHub用户doctashay完成，借助Xash3D FWGS引擎（GoldSrc引擎的重新实现）实现[1]。
该移植版本支持搭载G3和G4处理器的Mac电脑，系统要求为Mac OS 9.0或更高版本，建议至少配备8MB VRAM[1]。移植包中包含了原作《半条命》及其两个扩展包Blue Shift和Opposing Force[1]。
值得注意的是，Valve公司曾在1999年计划推出Mac OS 9版本，但最终该计划被取消[1]。直到2013年，Valve才发布了Mac OS X版本，但该版本针对的是Intel处理器架构[1]。
A GitHub user known as doctashay has successfully brought the classic first-person shooter Half-Life to Mac OS 9 running on PowerPC architecture, more than two decades after the original 1999 release target was missed [1]. The port utilizes the Xash3D FWGS engine, a reimplementation of the GoldSrc engine, and is compatible with Mac computers equipped with G3 and G4 processors [1]. The project includes not only the main Half-Life game but also its two expansion packs, Blue Shift and Opposing Force [1].
The game requires Mac OS 9.0 or later and at least 8MB of video memory [1]. This achievement is particularly notable given that Valve's official Mac release did not arrive until 2013, when the company released Half-Life for Mac OS X on Intel-based systems [1]. The original Mac OS 9 version had been planned by Valve for 1999 but was ultimately cancelled, leaving PowerPC Mac users without a native port of the landmark title for nearly three decades [1].
