Did you subscribe to mod dependency (PatchLoader) enabled it and followed the instructions?

Can you please go into this a bit more? I'm having the same issue on my mac.

I'm at step 4b. "Make sure you didn't forget about adding ./CitiesLoader.sh
or ./../../../Cities_Loader.sh to the game launch options
in the Steam Client"

Do we literally just add "./CitiesLoader.sh" (without quotes) to the launcher without adding + or some other full length address? Do we use + before +./CitiesLoader.sh ?

I haven't had to mess with the steam launcher before.

I get the same error on a non-M1 mac, Mid 2015 retina macbook pro....

Collect all logs from Logs directory and also game log (Player.log) create zip archive and upload to any free file sharing service (gdrive/oneDrive/dropbox etc.). I don't understand why it works for some but not for others :/

It's okay! I try to follow all the instructions but sometimes make mistakes. Let me know if the error logs shed light on a possible cause.

The cause is you probably forgot to change "exePath" value in the launcher-settings.json. That's required, without it FPS Booster won't work at all. launcher-settings.json is located inside Cities.app/Contents/Launcher (don't forget to make backup of that file)

I just had some issues with this on a Mac, but managed to solve it. After modifying the launcher json, the Paradox Launcher just had a little X when I tried to start the game, On trying to run the `Cities_loader.sh` manually, it exited with an error seemingly around a typo:


I got rid of the extra semi-colon, and it seems to work. Hope this helps/ is related.

Thanks, I'll check that be cause I think it might be a bug in PatchLoader mod (introduced in last update)

Just installed today and had the same double semicolon on line 5 of Cities_Loader.sh issue, removing the extra semicolon resolved, in case a second data point helps

Patch Loader mod has been updated. Disable and then enable the mod to recreate config file and fix the issue.

I am having the same problem and can't seem to find a way to get anything to work. Trying to run this on an M1 mac mini.

This is what I have in launcher-settings.json:

{
"formatVersion": 1,
"distPlatform": "steam",
"gameId": "cities_v2",
"displayName": "Cities: Skylines",
"exePath": "../Cities_Loader.sh",
"gameDataPath": "~/Library/Application Support/Colossal Order/Cities_Skylines",
"version": "1.13.3-f9",
"themeFile": "LauncherAssets/theme-settings.json",
"browserDlcUrl": "https://store.steampowered.com/dlc/255710",
"steamWorkshopDisabled": true,
"steamModsMigrationDisabled": true
}


Here is my log. I'm sure I'm missing something simple.

This is what I get when I open launcher-settings.json in terminal:

Firstly, to test it you should try to launch Cities_Loader.sh, not launcher-settings.json,
Secondly, exePath value is wrong, it should be ../../../Cities_Loader.sh not ../Cities_Loader.sh

Thanks for clarifying. I have changed the exePath value now to what you have suggested, but I'm still getting the same errors.

Updated error report plus I have included a copy of launcher-settings.json and Cities_Loader.sh (I couldn't find this file to start as it was not within the package content of Cities.app) incase that's helpful.

I only have a limited knowledge-base on this kind of stuff, so again apologies if I'm missing something obvious.

Also just want to thank you for all of your work. Your mods are an excellent addition to this game!

I assume you run game using Paradox Launcher (or Steam which opens it), right?
I've checked all files and everything looks good.
One thing you can try is:
- run game and in Content Manager disable PatchLoader mod. I will prompt for restart, so close game and before starting again do few more steps,
- completely delete Cities_Loader.sh, and revert the exePath to "../MacOS/Cities" (orginal value) or restore backup of launcher-settings.json if you created it before
- remove "doorstop.dylib" file, should be in the same directory as Cities_Loader.sh
- (optional, but recommended) restart Steam client app,

After that you can launch game normally and go to Content Manager to enable PatchLoader, then close game and change exePath in the launcher-settings.json again to ../../../Cities_Loader.sh, obviously save the file and start game. Hopefully at this point you won't see "critical error" dialog.

If above won't help then you can try launching Cities_Loader.sh in terminal and see what it returns (it may immediately run game, but is possible it will stuck on red screen - requires force close (Windows equivalent of Blue Screen)). If won't launch the game then error returned to terminal might help us solving the problem.
