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.
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.
