My 2017 MacBook Air's Messages app and Facetime is not working. Whenever I try to sign in it responds with "An error occured during authentication" or simply times out. Any idea how to fix this issue?
MacBook Air, macOS High Sierra (10.13.3)
Messages - If you can‘t sign in to your iMessage account or FaceTime on your Mac
Have someone else attempt to sign in using their Apple ID. If they can successfully sign in and use Messages/FaceTime, it may be your Apple ID.Someone I know had this happen and I was able to sign in usingmy Apple ID. After a call to Apple Support and then being elevated to a tier 2 support person, it turned out it was a problem with their Apple ID. It took the software engineers 3-4 days to fix the problem. When calling Apple, make sure you tell them it is an Apple ID problem so you don't get charged.
