Selenium in mac

Question

I am trying to run Selenium webdriver codes in Mac. But getting the below warning. Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

package pt;
import org.openqa.selenium.WebDriver;
//import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import org.openqa.*;
import org.*;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.*;

public class checknavnode {
public static void main(String[] args) 
{ System.setProperty
("webdriver.chrome.driver","/Users/user/Downloads/chromedriver");
    WebDriver driver = new ChromeDriver();
    String baseUrl = "https://www.google.com";  
    driver.get(baseUrl);
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.close();
 }
 }
