• Fix 1: Ensure your internet connection is working

• Fix 5: Install macOS from Terminal

Ensure your internet connection is working

An internet connection is necessary to contact the recovery server, so you must ensure your Mac is connected to a stable WiFi network. Click the WiFi menu in the top-right menu bar and select your WiFi network. If it's already selected, disconnect it and reconnect it again.

You can retry the installation now. If the error persists, consider switching to a different WiFi or using a wired connection with an ethernet cable. It's also a good idea to power cycle your router or modem and wait a few minutes to reconnect to your WiFi.

Check Apple server status

Though not common sometimes the issue lies on the server's end, especially when too many users request for the installer. You can check Apple's status page to see if relevant servers like macOS Software Update are not operating normally. If it is, the only thing you can do now is to wait and try again later.

Delete the installer and install it from the App Store

If the error appears when you are trying to update or upgrade macOS, you can likely eliminate the error by deleting the downloaded installer from your Applications folder and redownloading the full installer through the App Store or the links in this guide.

Note that if you receive the error "The recovery server could not be contacted" when updating to macOS Ventura from the Software Update pane, you don't need to delete the installer first, as it doesn't save the installer.

Keep running the installer a few times if the first attempt doesn't work properly, as some managed to succeed on the third or fourth try.

Install macOS in Internet Recovery

Alternatively, you can install macOS in Internet Recovery mode if you have an Intel-based Mac. Booting into Internet Recovery will allow you to install the latest macOS version compatible with your Mac. It will not remove your data if you don't erase your Mac.

Suppose your Mac still says "The recovery server could not be contacted" on macOS High Sierra or later; repeat the steps above but change the keyboard combination to Shift + Option + Command + R to install the macOS version shipped with your Mac or the closest available version. You can upgrade it in Software Update to the latest version compatible with your Mac afterward.

Install macOS from Terminal

You can also update your Mac by executing two simple commands in the built-in Terminal app. Here's how to do it.

Fix "The recovery server could not be contacted" on MacBook:

Note that you need to replace 'label' with the update you want to install and enclose the label in single quotes. For instance, if you want to install macOS Ventura 13.2-22D49, the command should be softwareupdate --install 'macOS Ventura 13.2-22D49'

Synchronize your Mac's date with the Apple server 

Contacting the Apple server needs reasonable clock synchronization. If the date and time on your Mac aren't properly synced with the Apple server, the macOS installation like macOS High Sierra can't connect to recovery server. To fix the error, you must reset the date and time settings.

If you can still boot up your Mac to the desktop, you can configure your Mac to set the date and time automatically.

Fix "The recovery server could not be contacted" on macOS Ventura/Sonoma:

Fix "The recovery server could not be contacted" on macOS Monterey, Big Sur, Catalina, Mojave, or High Sierra:

If you're in Recovery Mode, you can adjust your Mac's date to the actual time in Terminal, which you can access by selecting Utilities > Terminal from the top menu bar after clicking the OK button on the error and returning to the macOS Utilities window.

Some recommend running the command below in Terminal to synchronize with the server. But both of them failed with the error command not found: ntpdate on my Mac running Ventura. Give them a try if you get "The recovery server could not be contacted" when installing High Sierra or Sierra:

ntpdate -u time.apple.com

sudo ntpdate -u time.apple.com

I've also tried the following command, which returns "sntp: Clock select failed." Still, if you receive "The recovery server could not be contacted" while installing Mojave, Catalina, Big Sur, or Monterey, it may work for you.

sudo sntp -sS time.apple.com

If none of the above commands did the trick, you can manually correct the date and time using the steps below.

Erase your Mac

If macOS exhibits the message "The recovery server could not be contacted" when you attempt to reinstall macOS, you might have already erased your Mac. If so, you can skip this solution after you're certain that your Mac is formatted with the correct format and scheme.

Otherwise, you can erase your startup disk and clean install the operating system to get rid of the error. It's noteworthy that doing so will remove all data on your Mac. Therefore, you should back up your Mac with Time Machine or other ways before taking action.

If, unfortunately, the error "The recovery server could not be contacted" recurs after erasing your Mac, move on to the next solution.

Create a macOS bootable installer

If none of the above solutions have resolved the issue, you can install macOS from a bootable installer. To create the macOS bootable installer, you will need an external storage media like a USB flash drive with at least 14GB of storage, formatted as Mac OS Extended.

Since reformatting the drive will delete data on it, you should get the essential files off the drive first. Then, take the steps below.
