This implies that perhaps it’s not directly related to OS X 10.11.4 but rather is somehow related to Apple’s servers. What complicates this issue more is that users report even when downgrading to OS X 10.11.3, the log in issue persists. I don’t know how, when lower level tech support yesterday told me they were aware. Not sure what’s going on but he had no clue of this issue. I just spoke to senior support here in Canada. One user said they reached out to Apple Support regarding the problem and were informed that Apple is aware of it and working on a fix, while others report that Apple Support was unaware of the issue but would escalate it. Users have tried a variety o fixes, including performing a clean install, disabling Firewall, and turning on two-step authentication, but there is no fix at the moment that seems to work. The issue seems to mainly affect those who performed a clean install. Other users report that the log in process seems to act like its working, but it never fully completes and no error message is presented. A plethora of users are voicing issues on Apple’s support forums centered around logging in to iMessage and FaceTime following the update to OS X 10.11.4 El Capitan.Īccording to users on Apple’s forums, many are being presented with a “Could not sign into iMessage” error while trying to sign in, as well as a messaged reading, “An error occurred during authentication. Make sure that you are able to send messages/make calls before hanging up.Apple earlier this week released the public stable version of OS X 10.11.4, but for a number of users the update process has been less than pleasant. Once they confirm your Apple ID, they reset everything on their end and you should be set. Tell them how long that you've had this issue and they'll confirm your Apple ID.

They will ask for you Macbook Pro serial number and a "Customer Code" if you have one. Do that and you'll be connected (for free). Just stay on the line until you're asked if you wish to speak with a representative. If you say anything, you will be told that you either need to purchase a protection plan for $19.99 or literally "end the call". I waited 14 minutes but the representative found the issue then reset it and I was able to sign in.Ĭall 1-80 (It's free in the US or on Skype if you're in Europe!) When you call, you'll get the standard automated secretary. The problem is NOT on your end! I spoke with an Apple representative and they said that it is a "registration issue" and that THEY need to reset security settings.

If that doesn't work, contact Apple Support, per this post in the Apple Discussion Forums: In System Preferences > iCloud, log out and then log back in.
