在iMac/MacBook上, 如何禁止某个指定的网页网址


可以用以下命令修改配置文件
sudo nano /etc/hosts


1. 在 Finder 里找到应用程序 Terminal
2. 在 Terminal 里输入 sudo nano /etc/hosts
3. 输入管理员密码
4. 修改成 127.0.0.1 www.xxx.xxx
5. Ctrl+X 退出，按 Y 保存



It's just like in Windows, except it's a little trickier to access.
Use Finder to search for the application Terminal.
In there type: sudo pico /etc/hosts
Enter your root password.
Use the arrow keys to move down to the bottom line and then type:

127.0.0.1 www.thesiteyouwanttoblock.com

There is a space between 127.0.0.1 and www.

User Ctrl+X to exit and Y to Save.

Then type lookupd -flushcache

Quit the Terminal and restart Safari.
