iCloud Drive setup is taking an unusually long time
I recently upgraded to OS X Yosemite on my Macbook Pro laptop. I logged into iCloud in my System Preferences, and it said it was setting up the iCloud Drive. However, it has been loading for the past 3 hours.
I set up iCloud Drive on my iPhone 4S just fine. How do I fix this? Is there a way to restart the process?
MacBook Pro with Retina display, OS X Yosemite (10.10)
