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 JUST had this problem ...bought a new SSD and followed set up unplugged battery as instructed installed hard drive to have it say can't connect to recovery server...since I have had clock issues before with other computers I was suspicious.. 7 HOURS of trying to figure out what was wrong..granted if clock showed with new hard drive I would of checked it out there but no access to clock...I decided to put the old hard drive back since it was still working shut it off did not unplug battery this time ..turned it on ...and clock was wrong ...reset it and powered off leaving battery plugged in and reinstalled new hard drive and it worked ...update worked and OSX installed w/o a hitch...wish I saw this resolution before installation
