HI, I use MBP and this problem has been persisting for over 5 months now.
I am on El Capitan version 10.11.6. I get the message " An error occurred during activaton, Try again" when i try to Sign In.
My Internet speeds are ok, Password account ok. Already logged into iCloud and App Store with same password. Imessage + Facetime, I am not able to login.
Please help. Thanks
MacBook Pro, OS X El Capitan (10.11.6)
FOUND IT. You need to turn off automatic time updates and turn them back on. Why? Who on earth knows... If you can't sign in to your iMessage account or FaceTime on your Mac - Apple Support

I have the same problem. iPhone only shows the phone number. iPad and MacBook Pro with latest OS versions show same error message. 'An error occurred during activation. Try again" I followed various tips online but so far none of them worked.
I have the same problem on a Macbook Pro where imessages worked before. iCloud Preferences told me that my security had been compromised (no other explanation like location of suspicious logins or devices etc.) and that I had to change my iCloud password. That's when the problems started. I've sorted out all the other problems with my devices logging into iCloud services. But not FaceTime and Messages on the MBP.
I've followed the steps in the second link (except for waiting 24 hours). I've also tried logging out of iCloud in System Prefs and back in.
Then I tried generating an app-specific password as per the first link (that page by the way advises that this is for apps and services not provided by Apple) that didn't work either. So I turned off two-factor authentication. It still doesn't work!
Next step I'm investigating uninstalling Messages and reinstalling - unlikely to work if other Apple apps are anything to go by. Will repost here when the problem's solved, but meantime if anyone has anything that's worked when the above steps have failed, I'd appreciate your tips.
I contacted Apple as I can't sign in to FaceTime or iMessage on any of my devices. They are trying to figure out what's wrong. Has been 2 days already and no answer yet. As soon as they get back to me, I'll post their solution as long as they actually tell me what was wrong.
My FaceTime and iMessage wasn't working on MacBook air since 1.5 years. I had tried everything on the forums and today by chance I tried something just for the heck of it and it worked! I used a program called Appcleaner to delete all my FaceTime data. I opened the Appcleaner program, clicked on applications tab, searched for FaceTime. It pulled up a bunch of files related to FaceTime. I deleted all these FaceTime files and voila! FaceTime and iMessage started working perfectly. I can't tell the logic behind this but it worked for me. It is worth a try!
This didn't work. I've tried everything possible. I am sick of apple cloud. I have had this issue for about 2 or 3 years with no help. I can't recommend Apple products anymore. (Apple user since 1990).
Do you use two-step verification or two-factor authentication? If so, you will need app-specific passwords for FaceTime and Messages.
Using app-specific passwords - Apple Support
If not, see this article. It is written for iOS, but if you translate the suggestions into similar ones for OS X, it should solve your issue.

I tried the process given, and it did not work.
Apparently the iMessage and Facetime is able to login very well on SAFE MODE. But not able to login in Normal Mode.
Any idea how i can make it to login in Normal Mode?
Have you been through these steps?

Tried all the steps you have given in that link, but still not working. I had tried the process on that link before.
Apple Experts: Please help with more ideas on how to fix this problem.
