Fix: The Recovery Server Could Not Be Contacted – Mac OS Sierra

Fix: The Recovery Server Could Not Be Contacted – Mac OS Sierra

If you are trying to install Mac OS X (while in mac os recovery mode) onto a new volume on your Mac over your LAN network or Wi-Fi, you may receive an error.

 

The recovery server could not be contacted.

 

A solution provided by a user (Brano) on our site:

1. Launch Terminal and type:

 

ntpdate -u time.apple.com

 

 

Note: If you receive "operation not permitted" put sudo in front of the command.

 

sudo ntpdate -u time.apple.com

 


2. Proceed normally.

 


The problem is, SYSTEM DATE is wrong, and CERT validation is failing (https)

First, ensure your Mac is connected to a wired or wireless network. To connect wired network, plug an Ethernet cable in. To connect to a wireless network, go to the top right corner of the screen and choose the wireless icon and connect to a network.

If you are still experiencing the issue, it is very likely that the Apple servers are busy processing download requests for other users. You may also see your installation time rise significantly but come down suddenly over time.

 

If you are currently experiencing this issue, use the comment form below to let us now.

And what do you mean "launch Terminal"? From where? How? Techies are such crap communicators.

Hi there,

Thanks Brano. It took we time to find the terminal window. After going back and forth through the recovery menu options I finally found it.
1. Open Terminal
2. enter the line of code: ntpdate -u time.apple.com
3. wait 15 seconds. Get an incomprehensible answer
4. Quit the terminal
5. Start again the installation, it works

Good luck everyone. Been spending 2 hours, and it finally worked

Will now install Ubuntu on a partition of the disk

I tried this several times and got this error message. But after continuing it finally came through to the user agreement form. Crossing fingers that this solves the problem of my broke instalation.
