Create folders on mac

I'm trying to create folders (and files) on mac in my game in the folder provided by Unity (Application.dataPath) which leads to User/Library/Application Support/Appname

I can create the folders using a simple:

 if (!System.IO.Directory.Exists(pathMods))
         {
             System.IO.Directory.CreateDirectory(pathMods);
         }

The folder is created but I can't write anything inside. If I try to manually find the folder using Finder, it says I don't have access to it.

I haven't found any solution on google but it seems to be a pretty simple problem.

I have also tried to call this function with 777 but it didn't work:

     private static bool GrantAccess(string fullPath)
     {
         try
         {
 #if UNITY_STANDALONE_OSX
             sys_chmod(fullPath, 777);
 #else
             DirectoryInfo dInfo = new DirectoryInfo(fullPath);
             DirectorySecurity dSecurity = dInfo.GetAccessControl();
             dSecurity.AddAccessRule(new FileSystemAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), FileSystemRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.NoPropagateInherit, AccessControlType.Allow));
             dInfo.SetAccessControl(dSecurity);
 #endif
         }
         catch (PlatformNotSupportedException erreur)
         {
             try
             {
                 sys_chmod(fullPath, 777);
             }
             catch (Exception e2)
             {
                 LibTRANSVERSE.Helper.Monitoring.Exception(erreur2,  LibTRANSVERSE.Helper.MethodInfoHelper.GetCurrentMethod());
                 return false;
             }
         }
         catch (Exception e)
         {
             LibTRANSVERSE.Helper.Monitoring.Exception(erreur,  LibTRANSVERSE.Helper.MethodInfoHelper.GetCurrentMethod());
             return false;
         }
         return true;
     }
     [DllImport("libc", EntryPoint = "chmod", SetLastError = true)]
     private static extern int sys_chmod(string path, uint mode);

But it doesn't work.

To be complete all the folders don't have the same permissions for some reasons.
