Louis Wu at HBO, with a tip from momo, and MacCentral have posted, along with Sphtman who pointed us to a markedly similar IMG story, that Mac Halo has now entered beta status; so noted on Westlake's project page. MacCentral Senior Editor Peter Cohen, when asked about the status of a demo for Mac Halo, notes that there's no PC demo yet, but one is planned, so there may be one for Mac Halo as well.
