Hello sorry to hear your bad experience. Have you tried clicking the bell? I add a details that they will only come to you and interact when you call them by clicking the bell. As for the mac, it is really a hard issue to fix because of apple security for unknown developer. In order for me to fix this, I need a developer license for apple. However, we could do an alternate : could you perhaps can try to follow this
The desk is completely bare for me. No bell or anything!
In terms of the tutorial, when I tried downloading the game it wouldn't even open that far. I got no popup and I couldn't find it in my privacy settings. Not sure what happened there, since I've never seen that before. I have downloaded things from unidentified devs in the past and have dealt with it the way the video showed. That was not the issue I was experiencing.
