Fix for not bing able to open the game on mac:
1. Use 7zip. It is still the best to unzip to not get the game is damaged notice. Though you have to use the terminal version. Just ask a LLM of your liking on how you download and use the mac 7zip terminal version.
2. Once you downloaded and extracted the game: In the directory of the game in ~/RM4_2_mac.app/Contents/MacOS/
You need to change the file /RickAndMorty to be a executable through this command:
chmod +x /path/to/your/file
You need to change the path to the actual location where you saved the game in so
pathtoyourgame//RM4_2_mac.app/Contents/MacOS/RickAndMorty
That should be all to get it running on mac.
If you have issues. Try sloving it with chatGPT or something.
Just give it this Comment as context and add that you weren't able to get it running on your machine and that you need it to troubleshoot it with you.
For me that was all that was required to get it running though.
