While I'm primarily playing on a home desktop PC, I do have an old 2011 MacBook Air I carry around when out and about, so I was hoping to find a way to play Mania on the go without having to set up a dual boot since the SSD is so stinkin' small. And since Mania's saves are synced to Steam, I can continue my progress when I get back home, which is really cool. I went through a number of things before finally getting something to work. There's free Windows compatibility layers out there for Macs, such as Wine and PlayOnMac, and neither one of those would quite play nice for me. Then I found Crossover for Mac, which offers a free 14-day trial. It works beautifully and amazingly smooth, and I had no issues getting Steam installed and Mania subsequently installed. The catch with Crossover is that it costs $60 for a license if you intend to keep using it. I imagine it can be gotten other ways (I haven't checked), and if this is the only thing you're ever going to use it for, I wouldn't be too morally offended by choosing to do so; but more importantly if you're one of those folks out there that only has a Mac and no console, then 14 days should be more than enough time to beat the game a couple of times. Once you've got that done you can actually start playing immediately - using the keyboard (arrow keys for movement, A/S/Q/W are your action keys, and Enter is Start). If you want to play with an Xbox controller, you're in for more difficulty, though. The XB360/XBOne controllers don't seem to play nicely with MacOS directly at all; there's a 3rd party controller driver on GitHub, but unfortunately that doesn't quite bridge the gap into the Windows "not-emulation" within Crossover. I finally discovered Gamepad Companion, which I think costs $8 or so (there may be free alternatives, I haven't researched), and lets you map keyboard inputs to the controller inputs. This seems to work pretty well, but it doesn't seem to like any key being struck repeatedly quickly, so charging a spin dash seems to be finicky. I hope this helps anybody that was looking for a way to play this on a Mac. I didn't bother linking anything since Crossover For Mac is a quick search away and Gamepad Companion is on the app store.
