How can i turn off my internet with a mac computer?

To turn off your internet on a Mac computer, click on the Apple menu in the top-left corner, then select "System Preferences." Choose "Network" from the options, select your active network connection (like Wi-Fi or Ethernet), and click the "Disconnect" button or toggle the Wi-Fi switch off. Alternatively, you can simply click the Wi-Fi icon in the menu bar and select "Turn Wi-Fi Off" to disconnect from the internet quickly.
