I am on Sonoma 14.3.1, I believe I need to do something like the below but am having difficulty determining the correct dylib and APIs I can use in managed code. [DllImport("/usr/lib/libSystem.dylib", EntryPoint = "os_log_create")] private static extern IntPtr os_log_create(string subsystem, string category); [DllImport("libSystem.dylib")] private static extern int getpid();
