This update synchronizes the Mac version with the PC version 1.04 allowing cross-platform multiplayer to again function. Requires Halo v1.03. NOTE: You should disable your anti-virus software before running the updater. If you are reinstalling Halo, you need to first download the 1.03 update and install it prior to installing the 1.04 update.
