I just installed Sierra with no difficulty at all. However when I turn the machine on it shows a bogus warning that a USB device is using too much power and i have to unplug it to re-enable USB functionality. It's not true at all but it's annoying, cosmetically speaking. Any help would be appreciated. I know I'm not the first to have this problem but I can't find any solution on the forum. Everything seems to work, even Message, to my great surprise!
