It’s done in a similar way on macOS: a dylib is added to the bundle and an LC_LOAD command is added to the app binary. The dylib is the first thing that runs because of using the constructor attribute, like this: https://notes.alinpanaitiu.com/Injecting%20a%20DYLIB%20into%20a%20macOS%20app The nice thing is that a signed app will refuse to load a dylib that does not have the same signature. So crackers will be forced to change the whole app signature which can be easily detected in app code. I have that kind of protection in Lunar (https://lunar.fyi/) and Clop (https://lowtechguys.com/clop) and it seems to be good enough as they have no recent cracks.
