You update a domain&rsquo;s records, wait for propagation, then open a browser and the old site still loads. Or a site that used to work suddenly refuses to connect. The server is fine. Your internet is fine. The issue is that your Mac cached an outdated DNS answer and is still serving it.</p> <p>Flushing the DNS cache tells macOS to forget those stored answers and ask again from scratch. It takes one command and about five seconds.</p>
