Can't seem to install on MacOS

[ziaddemir]

Followed the instructions but get an error message when I try to launch the application. I do seem to be missing some files (I unpacked the Steam version's GAME.GOG using The Unarchiver) but I assumed those were specifically for the Expansion Pack.) See screenshots for the error message and my folder structure. I'm on an M2 Pro Macbook Pro and MacOS 14.4.1. Using the latest .dmg (tested the pre-release and a couple older versions as well, same result.)

I also had this issue. We will have to investigate what's broken. Sorry about that.

I'm not sure why this worked, but I was able to install with the following steps:

1. Mount the installer
2. Before dragging into the Applications folder, first double-click the app and open it. It will launch, then quit by itself after the Eidos logo since the game data hasn't been inserted yet.
3. Right-click the app, click "Show Package Contents," navigate to Content -> Resources. You don't have to do anything here, just opening the folder is enough.
4. Drag the app into the Applications folder, then add your game files following the instructions on Github. The game should launch fine now.

I'm suspecting this has something to do with MacOS permissions? Hope this helps in narrowing down a possible fix.

So the reason for this is going to be roughly something like this:

1. When you download a file from the internet, macOS automatically attaches a hidden attribute to the file (the com.apple.quarantine xattr)
2. When you try to open the file, the macOS Gatekeeper feature steps in an does two things:
   • Show you a warning dialog about # 1 which you can OK
   • If the file is code-signed and notarized (which our .dmg and app bundle are), it verifies that the signature is correct and matches the file contents
3. If # 2 is successful, the xattr is removed

That probably means if you modify the app bundle before running it for the first time, the signature verification will fail and the quarantine attrib doesn't get removed. If you run it first and the xattr gets dropped, you can modify the bundle afterwards. There's also ways to override Gatekeeper if your user account has admin privs, etc.

We have to change the install instructions accordingly. However, a better long-term solution is supporting to find & access the game data from outside the .app bundle to avoid the need to modify it, which of course would also make updating much easier and cleaner.

I've now confirmed the above experimentally - running first before copying in the data is fine, copying in before first run causes the verification to fail and the "app is damaged" popup.
