If you’re running macOS Sequoia or macOS Sonoma, you might occasionally find yourself in a situation where you need to flush the DNS cache on your Mac. This can be necessary to fix DNS related issues or errors, to clear out outdated DNS settings or records, to resolve issues with certain websites, or even to have the results of a modified hosts file or some other networking component to take effect. Knowing how to flush DNS cache on MacOS can be helpful for troubleshooting some network issues without needing to reboot the entire Mac too.
While flushing DNS cache is perhaps most relevant for more advanced Mac users, it’s fairly easy to accomplish with the execution of a simple Terminal command string.
