Apple initially delayed the launch of watchOS 2, its new smartwatch software, by a week due to an unexpected bug.
Fortune is here to help you avoid similar hiccups—here’s what you need to know to update that Apple-branded wrist-worn computer of yours without any problems.
The process is simple, but it will take some time. We recommend that you carve out about 20 minutes to complete the update.
Make sure your watch is attached to its charging cable and that it has at least 50% battery life. Keep your iPhone near the watch, too.
Inside the Apple Watch app on your phone, tap “General.” Then choose “Software Update,” which should be second on the list of options. Finally, press “Download and Install.”
The rest should be self-explanatory.
