fibric: looks like mac support has been silently canceld.
one dude on reddit wrote that 'someone' is still working on it but the absence of any press release or twitter update is pretty much telling...
wasted money
Luckly this is not true! There's an update from developers freom 4.06.2019. at
SteamCommunity.
1. MacOS version of the game.
As you know, Frostpunk for OS X was supposed to be launched in February but we decided to postpone the launch of this version due to some technical difficulties that were discovered at the very last moment. Over the past two months, we have been working hard to polish the game and while it’s not ready yet, we need to stress that, despite rumours, OS X version of the game has not been canceled - it is simply undergoing development and polish that has been deemed so needed back in February.
We’re very grateful for your patience and understanding, we are also well aware of your eagerness to get your hands on the game. It’s a letdown that Frostpunk still has not been released for OS X and we sincerely apologise for the inconvenience. We just feel that releasing the game in its current state, even despite all the work we put into it thus far, would mean giving you software that does not meet the quality standards that are expected of us. We’re deeply sorry for this situation - we’ve expanded our dev team to fix this version of Frostpunk and release it as soon as possible. We know that you’re expecting a release date and you have been waiting for it for quite a while - we’re doing our best to deliver the game you’re waiting for.
