If you decide the installation will never finish, force the MacBook to shut down by holding its power button for a long time (at least ten seconds or so). It may restart with the upgrade completely finished. Or, it might not restart at all. In any event you can't wait forever, so it's not as though you have much choice. Give it a few hours, at least.


Since it's new, consider contacting Apple: Contact Support. They'll fix whatever is wrong and it won't cost you anything but time.

Wait. That is normal as long as the installation continues. It will continue slowly but that number should drop given some time. If it doesn't and you'd like to try something more rather than take a trip to the Apple Store.
