If OWNERS like the API changes in general, It's probably enough just to add
something like

  base::scoped_nsobject<NSButton> checkbox;
  if (!checkbox_text.empty()) {
    checkbox.reset([[NSButton alloc] initWithFrame:NSZeroRect]);
    [checkbox setButtonType:NSSwitchButton];
    [checkbox setTitle:base::SysUTF16ToNSString(checkbox_text)];
    [checkbox sizeToFit];
    [alert setAccessoryView:checkbox];
  }

  NSInteger result = [alert runModal];
  if (result == NSAlertSecondButtonReturn))
    return MESSAGE_BOX_RESULT_NO

  if (checkbox)
    return ([checkbox state] == NSOnState) ? CHECKED : NOT;

  return MESSAGE_BOX_RESULT_YES;

(that's close to just using ShowMessageBox, but it needs a few other things,
like an icon).

Done.
Thank you very much, and sorry that I know nothing about cocoa.

   NSInteger result = [alert runModal];
   return (result == NSAlertSecondButtonReturn) ?
       MESSAGE_BOX_RESULT_NO : MESSAGE_BOX_RESULT_YES;
