How to Flush the DNS Cache on Mac
With Supercharge
- Open the settings of Supercharge, and click “Tools”.
- In the “Maintenance” section, click “Flush DNS Cache”.
- Enter your administrator password.
Flushing the DNS cache can fix connection problems after a DNS change, like a website that does not load after it moved to a new server, or a new DNS server that seems to have no effect.

Without an app
Open the Terminal app, and run this command:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
Enter your administrator password, and press Return. Terminal shows no characters while you type the password, and there is no output when it works. If you are comfortable with Terminal, this is just as good as the button.
