CyberBob first noticed this post at OBO's forum. Matt says:

Hey All- Just got word that the reworked Mac demo is almost ready to go. We'll be sending it to Gathering later today. They might run it through another testing gauntlet but in any case you shouldn't have to wait much longer. Thanks for being patient with us. :-) -Matt

So you folk in the Apple world won't be waiting much longer... perhaps it'll be here in time for a little Christmas carnage!
