As for the Apple thing, it’s usually kept up to date, but I can’t say for certain as I don’t use it. Best to email their support with any specific questions about that and Zsolt will be able to answer them definitively. (Incidentally I think Andras actually ran a windows emulator on his Mac at one of the trade shows before the actual Mac version of that update was ready.)
As for power supplies, I use a Strymon Zuma, but have also used a One Spot adaptor and a standard adaptor that comes with Source Audio pedals.
