Q: Can't login to iMessage and FaceTime

Same here. Also tried a recovery boot reinstall. Did not work. Might be an issues with keychain. Happy for any ideas.

Same here tried all the above and still wont sign in, any idea when this will be fixed?

Same here.....

i think that is Apple servers fault, maybe they have problems with efficiency, to many computers wants to activate iMessage and FaceTime

I've downgraded (clean install) OSX to 10.11.3 and problem still occur, so this is no software issue

Not likely. Activations work fine with OS X Yosemite, just not El Capitan.

See this thread: ** Clean Install OS X El Capitan 10.11.4 -- iMessage/FaceTime Activation Doesn't Work

I believe the issue is with a CLEAN INSTALL....

you are right but with 10.11.4

I've tried also with clean install 10.11.3 and the problem still occur, earlier I don't experience any problems with iMessage and FT activation on clean install 10.11.3

I did a clean install on my sisters MacBook Pro, and now she has the same problem and can't login to Messages and Facetime.

Tried several things to fix the problem, but nothing worked so far.

Same problem here -- reverted back to Yosemite until El Capitan issues are addressed. 

Unfortunately, it appears that updates are being released without thorough testing.  My late 2013 iMac is running stock Apple S/W -- no 3rd party apps with the exception of my HP ENVY print driver.

FaceTime is one of the apps that I use quite often to stay in touch with family.

Very dissappointed.

A reset of the keychain solved the issue. Can login to iMessage and FaceTime again.

how to reset keychain ? I have to delete them ?

Reseting keychain didn't work for me.

I was on the phone for about two hours yesterday with Apple Support got escalated all the way to engineering. Was told they would get back to me once engineering had something.

I just spoke to senior support here in Canada. Not sure what's going on but he had no clue of this issue. I don't know how when lower level tech support yesterday told me they were aware. He escalated it. I am really disappointed with Apple. They went through something like 7 iterations of this OS version and then released it with this major glitch. On top of that their website indicates all of their services are functioning well.

Reseting keychain also didn't work for me.
