How Do I Tether my iPhone to my Mac Laptop?

Before you Begin
Before you begin tethering your iPhone to use with your Mac Laptop to browse the web, contact your cell phone provider and have the tethering feature added to your iPhone data package. This allows you to connect your iPhone to your computer to browse the web. Install the latest software versions to your iPhone and your Mac laptop to ensure a successful tethering experience. Check for the latest updates by connecting your iPhone to your computer. Once iTunes populates, select the option to “Check for Update" and download the latest software versions to your iPhone and iTunes.
Turn the tethering feature on by accessing “Network” on your iPhone. Click “Set Up Internet Tethering,” select “Internet Tethering” and click “On.”
Connect iPhone and Mac Laptop via USB Cable
You will have the option to connect your iPhone with your laptop via Bluetooth or a USB cable in order to browse the web. Depending on your needs, you may choose either option. Bluetooth is preferable as you don’t have to carry a cable around with you which takes up unnecessary space. However, there may be a time when you do need to connect your iPhone and Mac laptop via a USB cable.
In order to tether your iPhone via USB, connect your laptop to the iPhone with the USB cable. iTunes will automatically populate. If you are connecting your iPhone to your Mac laptop for the first time, a pop-up window will appear displaying “A new network interface has been detected.”
Click “Network Preferences”, select the iPhone icon towards the left, and click “Apply.”
