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

Finally everything works like a charm 🙂

And thats why i think that problem is on the Apple side, a lot of El Capitan users upgrading their machines and Apple servers has huge problems with this traffic. Yosemite don't generates that huge traffic. For a few days we all activate our iM and FT on 10.11.4 🙂

Shame Apple Shame...........

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 FaceTime activation on clean install 10.11.3

Same situation here!!!! exactly the same, had Apple support over the phone for literally 2 hours ( Between Yesterday and today I reinstalled OSX ) to come to the conclusion that it seems to be indeed a problem with El Capitan... So now no FaceTime or iMessage on the mac at all until THEY decide WHEN to fix it... could be days, could be weeks... I don't know if I should feel angry or disappointed...

I was wondering is maybe putting the mac in internet recovery and then getting Mavericks ( which is the version my mac came with ) then log in to FaceTime and iMessage and THEN run the upgrade.....???? could that solve the issue??? if it does it sounds like quite the daunting procedure....

Also something that might be related - in Console I'm seeing the following message being generated every 3 seconds:

23/03/2016 12:09:53.919 apsd[74]: Certificate not yet generated

I had the same problem and finally took mine to the Genius bar where they went through several processes before getting it to work. It now works fine. I couldn't tell you exactly what they did but it was something like a hard reset, however all of my data was fine.

Do you have any inkling what they did? Anything at all would be helpful

"Access to my Mac" in System Preferences / iCloud don't work too... says: iCloud server don't respond.

I have also noticed that in Find My Phone app my MBP disappear 😟

all settings are ok, Find My Mac in iCloud settings are enabled

I have just checked and I have the same issue. It says I am connect to iCloud and the settings are enabled. However, it does not show up as a device in Find my iPhone and for me if I open up iMessages it fills in my apple ID and then just pinwheel like its thinking with no way to enter my iCloud password.

I have the same issue :

Cant login to iMessage or Facetime

Dont waste anymore time trying to troubleshoot this, after three and half hour call to apple support, there is just no fix... Dont waste more time... The only fix is for wait for Apple developers and engineers to decide when they want to take their fingers out if their &£@4ss and fix it...

for some reason i thibk that in an extreme situation... reverting one's mac to an older os like yosemite or mavericks then logging in from there (facetime and imessage, have it logged in, then apply the update, the logging info might stay in bypassibg the whole problem... But this idea is untested... If i had more time i would try but its just too much if a hassel.

I hope apple with prioritize this issue as is very embarrasing for them and mega über annoying for users...

I can log in to iMessage on my iMac that I upgraded to 10.11.4 from the Mac store. Just not my MBP I did a clean install on

Cool.. So from what you tell, your imac is fine but not your macbook pro?

the thing is that i was running 10.11.4 on tuesday and facetime was fine,as well as imessages it seems that it was fine. The problems seems to come when trying to log in on a fresh capitan install. When you upgraded el capitan in the imac, i presume facetime and imessage was logged in an enable wasnt it?
