I know ozkano from our local forum. There's no reason he'ld fake something like this. Also, macmini port was confirmed to be project Moana by some Acube developers, so it is REAL. However, legality of the issue is disputed. Also, it's not obivous yet as if it's possible to actually run OS4 on the macmini, there's no information to if it's possible to install it on the device.
