Your computer is configured to surf the web with DNS Protection enabled. DNS Protection blocks phishing, crypto-mining, malware, and other nefarious websites. These protections help mitigate the chances of being hacked and/or getting malware/viruses on your computer.
Pictured below are the filters that are applied to your Mac.
GREY = ALLOWED
PINK = BLOCKED
If you come across a website that is blocked and you would still like to access the site, you may do so by clicking BYPASS BLOCK. Then type “letmein” in the password area. This will bypass the DNS Protections and allow you into the site.
