Facetime For Mac Sierra

 admin

Hi Paritosh23,
As I understand your post you're having an issue with FaceTime connecting even though it was functional before updating to macOS Sierra.
A good resource with several additional links for troubleshooting is the FaceTime for Mac document.

It would not hurt to review the entire resource, but the section with the heading, Troubleshooting FaceTime for Mac seems to apply best as I understand your issue.
Thank you for using Apple Support Communities. Have a great day.

Like group FaceTime calls with iOS 12.1, video chats with multiple people are possible on a Mac with MacOS Mojave 10.14.1. And unlike on the cramped quarters of your iPhone, you'll have plenty of. Aug 28, 2017  So, just to make sure I've understood this. If I've a MacBook properly running iMessage and FaceTime (with Sierra), is it as simple to get them work in my Hack as copying the S/N, ROM, SmUUID values from one system to the other? Cheers.I think this assumption is incorrect. Try these troubleshooting steps FaceTime for Mac: Troubleshooting FaceTime. Upgrade to Sierra 10.12.2. Facetime problem with isight firewire is solved upon. Nov 29, 2016  Hello, I had recently updated my MacBook Pro to the latest OS Sierra. Since updating my mac has been giving issues with FaceTime.

Apple rightfully has a reputation of having its products 'just work.' And 99% of the time, that adage holds true. Until it doesn't. When things do go wrong, Apple's error messages are cryptic, at times offering no obvious clue as to how to remedy them. One such error is the 'Authentication Error' message when trying to log into iMessage and FaceTime on your Mac, even if you've successfully logged into iCloud.

If your Mac isn't compatible with OS X El Capitan, the installer will let you know. Counter strike 1.6 for macos high sierra. You can upgrade to OS X El Capitan from on any of the following Mac models.

The problem

For a non-obvious reason, my previously properly running Mac could no longer log into iMessage or FaceTime despite being successfully logged into iCloud. Notes synced, Documents synced, Photos was working, etc.

Trying to log into iMessage triggers my two-factor authentication mechanism as expected. But when prompted for my iCloud username and password, and after a long timeout period, I simply get an 'Authentication Error.'

The potential fix

The fix involves getting Apple's servers to re-initialize your Mac hardware to be allowed to access your iCloud services.
