The Mac|Life 101 series is where you can come to learn new and simple ways to do things with Apple’s desktop and mobile operating systems. Whether you’re new to the platform, or just want to learn a new technique, then MacLife 101 is for you.
Whether you’re traveling, or in a situation where you need to use your iPad or iPhone where there is little or no Wi-Fi, there’s a solution, and it involves your Mac. With almost all Macs shipping in the past 10 years, you can instantly create a Wi-Fi or ethernet network by simply turning on a few switches in System Preferences. This is great for those times when you need a Wi-Fi or ethernet connection and don’t have access to a router.
