I think we have to wait until Apple fixes this.
Mac version of Backrooms should be still playable on older MacOS versions though.
Alright, it's okay thanks at least for trying to help me :3
Sorry again :( You can still try Backrooms for WebGL, Android or other operating systems.
i can solve your problem :0. all you need to do is install the itch.io app and it'll give you access to any game. This solved my problems with opening several other games. I hope it helps. if you have any more questions, please feel free to ask. I'd certainly walk you through if you need any more help
