Unable to login to iCloud - Verification Code Loop
I just got an early 2013 MacBook Pro Retina and it can't sign into iCloud. Almost every time I try it gets to the verification code and then promptly pushes me back to the sign-in page where it asks for my password again and then another verification code.
Occasionally, it shows the iCloud account for just a second (but as inactive) but it then immediately disappears. I also have a Mac mini, iPad, and iPhone and they all have no problems with iCloud.
