As many skins on microgaming now support the mac (Stan James, 24h, Triobet,Betsson to name a few), I see no reason why it can’t be in future release of PT4

I know it's something on our radar, but I can't say more than that at this time.

As far as we can tell the MicroGaming software on Mac is an Adobe Air app which doesn't have any option to save hand histories and doesn't appear to do it by default. They could add them in the future but at this point there's nothing to import.
