I'm sorry to hear that. Mac support is tough to do continuously, as you always need the hardware for it. With Linux, I could just install whatever distro someone is using and run some tests. Maybe you can boot camp a linux mint or windows for the games that aren't working properly.
Yeah, my roommate said I might be able to borrow their computer, which looks like my best option right now. Really wish I hadn't updated it, but oh well. Thanks anyway!
I am not sure if it is Catalina. Usually games that are not able to work won't even open. Either way, once I get a PC, I will definitely come back to this game and give a review.
