Only the very first few models of Intel Macs had strictly 32-bit processors (the 2006 iMac and Mac minis with Core Solo/Core Duo processors), and none of them were realistically capable of playing Half-Life 2. Apple is guilty of many sins, but this isn't one of them. Valve should never have shipped a 32-bit application in the first place. The binary was already obsolete before it even left Bellevue.
