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

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.

Thanks for the detailed help, but the most frequently occuring issue here is a discrepancy in the system date, which is likely due to a user resetting the VRam or SMC.


To enable the update server to accept the request, a user must change the date in Terminal to the current date.


Step 1) Press Power Button and immediately press ‘Command + R’ (this will boot computer into Restore Mode)


Step 2) At the option screen, there are 4 Options, however, use the mouse on the Menu Bar (top of the screen) to open ‘Terminal Utility’


Step 3) In the terminal window type the command ‘date’ which will display the time that the system thinks is the current date. If this date is not correct, (will likely say something in 2001), you’ve found the issue.


Step 4) Change the date to the correct time and date by using the ‘date’ command:


date MMDDhhmmYY


Example for January, 1st, 2018 at 12:34 am:


date 0101123418


Once you type the current date and time exactly in the format above, your system will modify the time. You can type ‘date’ then hit enter to have the system display the time, if the system now states the time as that which you entered, you’re ready to move on to restore.


You can now exit Terminal by Command + Q or selecting with the mouse from the menu File > Quit Terminal.


It will bring you back to the main screen which includes those four options. Select ‘Restore MacOS’ then hit Continue.


As long as an internet connection is active, your system will begin downloading the installer files. If you get to the Disclaimer Accept prompt, you’re connected.


PRO TIP: You should use an Ethernet cable to connect your computer to the modem (fastest) or router (faster, depending on hardware), but you can also use Wi-fi (slowest).


You can use Terminal Utility to determine whether you have an internet connection (I’d leave more details here but you should find a help article for that elsewhere.
