Apple presented new OS X 10.11.4 version for Mac machines. Still users who hurried to update all the newest releases note that they are unable to sign into iMessage on Mac after upgrade [learn how to unlink your iPhone number from iMessage] and experience other unpleasant issues.
According to Mac users who are now running OS X 10.11.4 they also have FaceTime not working on Mac bug. Both iMessage and FaceTime cause problems to Apple fans. It seems that clean install of new OS X brings the bugs which users have to deal with.
Is there a fix to known OS X 10.11.4 issues or not? Apple doesn’t share any comments since the company is busy presenting new iOS 9.3 features and new products this spring. Users keep trying to sign in to their FaceTime / iMessage programs and fail because they see only the error message on computers.
Nothing happens and users complain about their problems. Some of them try different ways and advice on how to solve the issue. Users say that their FaceTime and iMessage start to work after they log out of their iCloud account and turn off 2-factor authentication. Still not all Mac owners were able to fix everything this way.
In other words, if you have the problems with signing in to your iMessage / FaceTime app you should wait until Apple fixes the bug. Will the company offer another OS X update? It would probably have to. Otherwise you can keep your fingers crossed and try the ‘iCloud log out’ solution. Maybe you will be lucky to make it work.
