Apple today began automatically downloading macOS Sierra to Macs that have yet to upgrade to the new operating system, taking a step that rival Microsoft was criticized for last year.
Although the upgrade to macOS 10.12 will automatically download to eligible Macs, it will not automatically install. Instead, users must authorize the upgrade after being notified that it has been retrieved and is ready to install. Users may also decline the upgrade at that same notification.
Now they are all at it!!
