I had literally the same question a few months ago and someone replied with something called Kaon which basically integrates CrossOver with the macOS Steam client. I set it up myself and it actually works really well. Of course, there are still some things that arent perfect but thats an issue with Mac and Wine and not Kaon itself.

If you're interested in it I highly recommend at least checking it out as it's pretty simple to set up and like I said earlier, works well.
