If you want to save your wifi data or make it more private you can use the Norton wifi privacy software. Open your browser and go to the official website of the Norton and choose wifi and privacy.
In the website select the number of devices and subscribe then, follow the screen instruction you will be able to install Norton wifi privacy on your computer.
It will be a little different when you will install it on Mac but you should be able to do that or you can call on the Norton customer support number.
