I wanted to upgrade my iWatch to 6.2. It did the download and the verify and yet when it came time to install; it would error off with the nondescript “An error occurred while…..”
I checked the space and the network connections and everything was fine. While checking the settings on the watch; I happened on the System Update and decided to click “install” It did a quick verify and the installation began. Of course it needed to have power. Strange…..
