Get a terminal window, frome the recovery menu. The menu bar at the top, not the window dot in the middle. Then enter the date command and you should see some some old date at January 1st. My MBP has a battery problem and wasn’t plugged in for a while so the system date got reset.


To fix type


date 1016200017


which is October 16th 20:00 (or 8pm) 2017.

So mmddhhmiyy

all two digits.


After that recovery worked. Must have something to do with certificate validity or something maybe.

I have found one other solution to the problem. In disk utilities click on apple add and delete it, not erase, but delete it and everything else that is there. Keep only the OS X base system. Then check to make sure you have a WiFi connection and shut off the computer. You now need to boot into recovery mode and from there go to disk utilities. You should notice your sad is back along with other greets out drives. Click the apple sad and click erase, rename it as Macintosh HD, format it as OS X Extended Journaled, and choose guid partition map underneath that. You may exit utilities and click reinstall OS X, good luck:)

Have you tried the solution from this post: Re: The recovery server could not be contacted.


If yes and it didn't work out, you can try searching for the solution out of the apple discussion.


I have searched and found different things, I don't know if these might help you since I can't test them but, you can just check it out:

I am not sure why it won't let you change the time. I am not a mac expert here or anything, just willing to share what I've figured.


I apple, it's either you DIY, bring your mac to them to fix it, have a geek friend to fix it for you, or nothing else. I'll leave the rest to you.


Best of luck.

I recently bought this used Mac from a family member who hasn’t used it in a long time and forgot their password. I had to wipe it clean and restart fresh, I can’t reinstall because of that error message. I have looked at many different alternatives via google and have also contacted Apple support to which they say since it just came out 2 days ago that there is high volume and the server is jammed up and I have to keep trying for hours as I’m their words even days!

Just saw this post and haven't been able to try this yet. My issue is that when I try to erase and do the APFS (encrypted) it asks for a password...well I just bought the computer used and have no clue what the password would be since there is no user- or at least I thought. I'm assuming they reset it. I'm getting ready to ask the seller, but it's a refurbed computer so it's hard telling if anyone is going to have access to a password. I need help 😕

Jo Desmet, brilliant. This worked.


In Windows Server if a machine is off from the UTC date/time the server won't communicate with the machine. The server is like, "Hey wow, if your time doesn't jive with mine then there is no way you are from my network: Stranger Danger!!!"


Thanks for the elegant solution. I'm going to have to save this in my brain and notes!!

are there any other solutions? im about to make my own question because i have tried the new user and setting the time and i still have issues but before that ill ask here. I can't even manually download the patch either. Im on 10.12.6 and it just won't bloody work the support site only has a 10.13.1 update and a 10.13 supplemental which both require 10.13. I am using a mid 2014 macbook pro so it should run it. I swear this happens every time i want to update.


First clicking on the updates button in the app store results in a "an error has occurred" and "can't connect to the apple software update server" but i was able to update Xcode. I can download like a 19mb file from the app store for high sierra but when i run it i get "the recovery server could not be contacted" but i checked the site and everything is running on green! And i do have an internet connection on the mac otherwise i would not be here posting this!


I don't get how i always have so much trouble with a simple freaking OS update. I thought apple was supposed to be more reliable than windows.
