How To Fix The Error ‘site can’t be reached’ On Mac? || 5 Ways In 2022

Imagine this: you’re all set to write the next great American novel, but when you sit down to your computer, the screen is just blank. You try again and again, but no matter what you do, that pesky message pops up – “SITE CAN’T BE REACHED.”

Don’t worry, your computer isn’t broken – at least not yet. This error can be caused by a number of different factors, ranging from a simple typo in your web address to a more serious issue with your network connection.

In this blog post, we’ll explore five ways to fix the “site can’t be reached” error on Mac computers. Stay tuned!

DNS cache poisoning:

One of the most common causes of the ‘site can’t be reached’ error is DNS cache poisoning. This happens when someone maliciously alters the DNS records for a particular website, redirecting users to a different (and usually malicious) site.

To fix this problem, you can clear your DNS cache by following these steps:

  • Open the Terminal application.
  • Type in the following command and press Enter: sudo dscacheutil -flushcache
  • Type your password when prompted and press Enter again.
  • Close the Terminal window.

Your DNS cache should now be cleared and you should be able to access the website in question without any problem. If you’re still having trouble, you can try changing your DNS server to a public DNS server like 8.8.8.8 (Google), 4.2.2.4 (Level 3), or 9.9.9.9 (Quad9). To do this, follow these steps:

  • Open System Preferences and click on the Network icon.
  • Select the network connection you’re using (e.g. Ethernet or Wi-Fi) and click on the Advanced button at the bottom-right of the window.
  • Click on the DNS tab and remove any existing DNS servers by clicking on the minus (-) button.
  • Click on the plus (+) button and add one of the following DNS servers: 8.8.8.8, 4.2.2.4, or 9.9.9.9.
  • Click on the Apply button to save your changes and then close the window.

Check for a misconfigured firewall

If you’re using a firewall, make sure that it’s configured correctly. If you’re not sure how to do this, contact your network administrator or the manufacturer of your firewall software. This  is often the cause of the error message ‘site can’t be reached’.

And  this is especially common if you’re trying to access a website from behind a corporate firewall. So,  check with your network administrator to see if this is the case.

Restart your router

One of the first things you should try when you see the error message ‘site can’t be reached’ is to restart your router. This will reset your connection to the internet and  might fix the problem.

To do this, simply unplug your router from the power outlet, wait a few seconds, and then plug it back in.

Disable IPv6 on your computer:

On Mac, you can turn off IPv6 by going to System Preferences > Network. Select your active network interface (Wi-Fi or Ethernet), then click the “Advanced” button in the lower-right corner.

Under the “IPv6” heading, select “Off”. And  finally, click “OK” to save your changes.

If you’re still seeing the “site can’t be reached” error after disabling IPv6, try flushing your DNS cache. This will clear any outdated DNS entries that might be causing problems.

To flush your DNS cache on Mac, open the Terminal and enter the following command: dscacheutil -flushcache

If you’re still having trouble, the next step is to reset your network settings. This will remove any custom DNS entries or other tweaks that might be causing problems.

To reset your network settings on Mac, go to System Preferences > Network. Select your active network interface (Wi-Fi or Ethernet), then click the “Advanced” button in the lower-right corner. Click the “TCP/IP” tab, then click the “Renew DHCP Lease” button. Finally, click “Apply” to save your changes.

Use a different browser

 If you are having trouble opening a particular website in Safari, try accessing it using another browser like Google Chrome or Mozilla Firefox.

Clear the cache: Clearing the cache can help resolve many issues related to loading webpages. To clear the cache in Safari, go to Preferences > Advanced and click on the “Show Develop menu” tab. Now, select “Empty Cache” from the Develop menu.
