Simply editing /etc/hosts on a modern Mac (Ventura, Sonoma, Sequoia) is not enough. Here is why your setup may fail:

Below is the updated, aggressive, and redundant list of hosts file entries specifically designed for macOS Ventura, Sonoma, and Sequoia.

Open Terminal and type:

sudo nano /etc/hosts

Enter your password, then paste the following block at the bottom of the file:

Yes, but with caveats.

The hosts file on your Mac (and on any computer) is a plain text file used to map hostnames to IP addresses. It is a crucial part of the DNS (Domain Name System) resolution process. By editing this file, you can redirect requests from your computer to certain websites, including servers used for software activation, to a non-existent or a local IP address, effectively blocking them.

sudo nano /etc/hosts

Then flush DNS:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
