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've tried all these "solutions" and this is not working. The latest "ifconfig et1 up" does not work either. This has been going on for a week now...about to throw computer out the window.

it's because of network connection issue

SOLUTION : in recovery mode go to TERMINAL and write a command line

ifconfig et1 up

close terminal and try install Sierra again... works for me. Issue seems to to with WIFI or LAN inactive (check your network status)

This does not work.

Typed it in the terminal and got this message:

24 Jan 12:29:22 ntpdate[6452]: Can't adjust the time of day: Operation not permitted

Now what? This is ridiculous.

I am in the process of restoring my iMac. I got to the point where I was prompted to install the new OS. I received the message:"The recovery server could not be contacted.". When trying to change date in Terminal the keyboard was unresponsive. I do not know how to get past this. Do I need a a wired USB keyboard?

Help

Changing the date worked to the point in the installation where it says "select the disk where you want to install macOS" I have no options on my screen and all it is allowing me to do is click "back" arrow. I have restarted it a few times to get stuck at this point.. Please help!

Typed this: ntpdate -u time.apple.com

Typed this: sudo ntpdate -u time.apple.com

Worked for me. I also had to delete the "InstallInfo.plist" file from my installer package. If you run into an issue where it says "This copy of Mac Os high sierra is damaged. cannot be used to install mac os" when you try to install from a bootable USB, then you have to delete that file. Here's how...

Step 1. Go to your applications folder.

Step 2. Find the installer for macOS Sierra.

Step 3. Right click on the installer and click "Show Package Contents".

Step 4. Click on folder named "Contents".

Step 5. Click on the folder named "SharedSupport".

Step 6. Delete the file named "InstallInfo.plist".

Step 7. Enter your administer password to confirm.

Step 8. Now open the installer.

Once you get past this, that is when you'll run into the "recovery server" issue. Run that "ntpdate -u time.apple.com" from a terminal window and you should be good to go. It worked for me.
