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.

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.

I downloaded Sierra last night and went through the installation process. This morning the computer said it timed out and click continue to restart download. I did and the computer restarted but in 10.9.5. App Store says it is INSTALLED but he the About this Mac says it isn't. So I clicked on the Install icon in the applications and I got the server can't be found. Followed all the fixes here and now it is re-installing but it seems stuck. How long does it take to upgrade from 10.9.5?
