MacBook stuck while upgrading to iCloud Drive
I just bought a new MacBook Pro and in the setup process I was asked if I wanted to upgrade to iCloud Drive.
I chose to upgrade, but now my new computer is stuck in the upgrade and the spinning thing won't stop. It has been going on for about 15 minutes by now.
What should I do to solve this problem? Or is it normal, that it takes a lot of time?
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
