That’s alright you can download a copy of Fusion Player for free, you just need to create an account for free. You can use this guide from VMware if it’s to complicated I can help you get it because the guides are really over complicated sometimes

For such a low level game like this that can run on basic versions of windows and linux you can use Wine on your Mac to do so or be like me and just us Fusion instead. but yeah we need a Mac version for the steam release.
