Game won't start on macOS Catalina

[Mary13]

I tried to find a solution on the Internet and found that this problem has existed since 2018. Today is 2020 and after two years the game still does not start.
For a game that has not been able to start for two years, you take money. Hmm

Was macOS Catalina release in 2019?

Anyway...

I've solved this on my Mac for a totally different game, but exactly the same error and behaviour. Here's what I did.

On MY Mac, my steam games are stored in this location:

/Volumes/Geode/Shared/Steam/

On a more conventional setup, your games are probably stored in:

/Users/yourname/Library/Application Support/Steam

The game that was giving me trouble was “Adventure Pals”. If I clicked on it in Steam, I got the OS Error. If I follow these steps, the game runs.

1. Start a Terminal (Go to Applications, Utilities, and double-click Terminal). This gets you a command line where you can type commands.
   
2. In the terminal, type:

   cd Library/Application\ Support/Steam/steamapps/common

3. Type

   ls

   and press Enter. This will list what games you have. In my case I could see a folder called

   The Adventure Pals

   .
4. I needed to find the program to run. In my case that means typing 2 commands:

   cd "The Adventure Pals/Adventure Pals.app/Contents/MacOS"

   and then

   ./"Adventure Pals”

   . When I did this, the game ran.

To make it easier, I created a shortcut on my desktop so that I wouldn’t have to do this every time. This command creates an (ugly looking, but effective) shortcut that launches the game when I click it.

ln -s "/Volumes/Geode/Shared/Steam/steamapps/common/The Adventure Pals/Adventure Pals.app/Contents/MacOS/Adventure Pals" ~/Desktop/

I don’t know what’s causing Steam to fail to launch the app from within the Steam desktop. But this totally works fine. If you want to do this for another game, you need to follow the steps, but change words like “The Adventure Pals" with EmergeNYC_Mac or whatever your game is called. There’s no magic fix or generic way to do this. This is just a clunky workaround. Hope this helps someone.

All this is doing is finding the program file on the hard disk and executing it directly. There is no danger to any of the commands I've suggested typing. You're just looking at files and asking the computer to run some commands.

This worked for me, I re-installed it as well to check another fix and it seems to be the input monitoring permissions in system preferences on Catalina stoped it from opening, can't 100% verify it was that but it worked.

above solution worked - just started the program from the desktop and had to wait over 30min for the game to load the first time but from then on it was fine
