Not able to login to Apple ID
I’ve been trying to log into my Apple account on my Apple iMac as it’s currently on Mac OS X Yosemite and I want to update it. I have tried to login with my account and even create another account and neither works when I log in it asks for a 6 digit code which I put it in and it still won’t let me in.
iMac 21.5″, OS X 10.10
