For clarification, Halo on Macs have a windowed and full screen mode, just like on a PC.
Halo PC runs on Windows machines and is the exact same as Halo for Macs. Halo CE stands for Halo Custom Edition, and as Iamwhie says, is only the multiplayer portion of the game. This version has only been released for Windows architecture. It's a free download for those who own a legal copy of Halo PC, and has several perks, such as increased frame rates, support for the creation and playing of custom content (like, maps, vehicles, weapons, etc.).
