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.

Terminal is rude, say o such command, no such interface.
WiFi works as I am able to get Safari through.
This text is with another machine, though, one I upgraded yesterday.
