Describe the bug It used to be possible to patch the DLL in Windows (up until around Cosmic Update), and then copy the DLLs to the Mac version of ONI, but this is no longer possible.

Expected behavior ONI boots corrects as previously in Cosmic Update

Current behavior An error message appears in the Unity log, and ONI freezes at the KLEI screen.

To Reproduce Steps to reproduce the behavior:

1. Inject ModLoader in Windows and verify that ONI loads.
2. Copy patched DLLs, and files in Managed folder to MacOS OxygenNotIncluded.app/Contents/Resources/Data/Managed
3. Start ONI from Steam menu (no actual mods copied to Mods folder yet)
4. See unity error log:

---

FileNotFoundException: Could not load file or assembly '/Users/xxxxxx/Library/Application Support/Steam/steamapps/common/OxygenNotIncluded/OxygenNotIncluded.app/Contents/Resources/Data/Managed\ModLoader.dll' or one of its dependencies. The system cannot find the file specified. at (wrapper managed-to-native) System.Reflection.Assembly:LoadFrom (string,bool) at System.Reflection.Assembly.LoadFrom (System.String assemblyFile) [0x00000] in :0 at LaunchInitializer.Update () [0x00000] in :0

Mmmm, this is going to be a little hard, I don't have MacOS. I'll have a look to the injector to check if everything is ok. The injection was modified to handle paths in different OSs but since you are doing it in Windows and moving it to Mac I don't know the behavior. Do you have mono available in mac? It should be possible to run the injector in Mac with it. Thanks for filling the issue.

Thank you very much for this hint! I was able to get the ModLoader working in MacOS:

1. Install newest stable version of Mono from https://www.mono-project.com.
2. Open terminal and cd to '/Users//Library/Application Support/Steam/steamapps/common/OxygenNotIncluded/OxygenNotIncluded.app/Contents/Resources/Data/Managed'
3. run "mono injector.exe"

Glad that it worked. I'll update the instructions.
