A new patch for the Windows version of Halo — published by Microsoft — was recently distributed that corrected security issues in online play. Unfortunately, that update prevented users of the Mac version — published by Destineer studio MacSoft — from playing on updated Halo servers on the Internet. That issue has been corrected in
a new Mac update
(v1.053) released Friday. The update also adds support for vertex and pixel shading graphics effects produced by the Nvidia 6800 Ultra video card available as a build-to-order option on Power Mac G5 systems.
