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.

I have been trying to install from el capital to mohave to catalina with no luck just the same stupid error, Tried the terminal command, cleaning disk, restart, changing the clock in settings, everything to no avail. The only thing I think I may be doing wrong is that I am connecting to my phone's internet access via blue tooth and sharing wifi as I do not have a fixed wifi connection at home via broadband. Could this be the issue?

My MacBook pro is from this year, stuck in Mojave, and those terminal commands return "command not found". This thing will not reinstall the OS. It will not update.

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.
