Cannot complete set up for new Mac Book Pro
The initial set up was taking a long time so shut down our new Mac Book Pro. Now when it goes through start-up it gets just over half way and a circle with a slash through it appears on a black screen. Cannot progress beyond this point, just took it out of the box a couple of hours ago.
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
