On WDL (Tale and Ol) the function for Mac is

bool IGraphicsMac::OpenURL(const char* url, const char* msgWindowTitle, const char* confirmMsg, const char* errMsgOnFailure)
{
  #pragma REMINDER("Warning and error messages for OpenURL not implemented")
  NSURL* pURL = 0;
  if (strstr(url, "http"))
  {
    pURL = [NSURL URLWithString:ToNSString(url)];
  }
  else
  {
    pURL = [NSURL fileURLWithPath:ToNSString(url)];
  }
  if (pURL)
  {
    bool ok = ([[NSWorkspace sharedWorkspace] openURL:pURL]);
    // [pURL release];
    return ok;
  }
  return true;
}
