Community developer ports Half-Life to PowerPC Macs running Mac OS 9 nearly three decades after its original release

Half-Life is now playable on G3 and G4 PowerPC Macs running Mac OS 9.0 or later, using a fork of the Xash3D FWGS GoldSrc engine reimplementation. The port supports the full game, multiplayer, Uplink, and downloads for Blue Shift and Opposing Force, though performance depends heavily on available GPU and VRAM.

The release fills a long-standing gap after Valve canceled its planned Mac OS 9 version in 1999 and did not bring Half-Life to Mac until the Intel-era OS X release in 2013. It highlights the durability of retrocomputing communities and how open-source engine work can extend classic games to platforms their original publishers abandoned.
