Nate Birkholz posted a Myth III status update for the Mac in the Myth Village forum. It says:

Yes Myth III is being worked on; Bill Heineman has been working on it for a couple weeks now, along with Chris Jacobson.

The A-level bug list remains the same, but progress has been made.

Changes have been rolled in from the forthcoming PC patch.

The ship date has slipped to early December due to the delay in receiving the final version.

Webscreamer asked about the demo and if it would be released before the full version. Birkholz replied: indubitably .
