Cannot log into iCloud get the following message "cannot log into.....
there was a problem verifying the identity of this Mac. Try restarting then sign in again".
I have done so many many times......continue to get the same response. This is on a Macbook Pro 9.2
Then cannot change the iCloud items and this machine does not show on iCloud.com. All of my others do.
Please assist.
MacBook Pro, OS X Yosemite (10.10.4)
