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.

I have the correct date but still getting recovery server error. There is no wifi on/ off option in top right corner. On an old 2009 iMac

I can't launch Terminal. Is it Command-spacebar when your mac isn't turning on? This gets me a blinking question mark in a grey box.

It's probably not the problem you're having but I wasn't connecting to the internet even though I entered my password and it was accepted. While on the phone with Apple tech support, it was suggested that I probably wasn't connected to the internet. I saw that the Wi-Fi symbol in the menu bar was grayed out, selected it, entered my password there and voilà, I was able to reach the recovery server and easily install Mac OS X 10.14.5.
