Downloading insurgence on mac

I was trying to download Pokémon insurgence for a while I downloaded the Xquartz and then I went to the download and clicked to download it. Then I downloaded wineskin winery and did the steps I’ve seen in previous responses and I didn’t know what to do as one of the step said to change the engine for the game and I went to go change it and there wasn’t any engine to change and I went to start it up and it said Mac OS X can not open this app. I don’t know what I did wrong if anyone can help please email me

Make sure the Wineskin is updated.

How do I do that?
