How does macOS High Sierra work for you? Some users highlight its new features and bug fixes. However, there are also those who have different problems with this OS version. Sometimes when installing High Sierra update from the App Store users get the error “The recovery server cannot be contacted”. Below we are going to provide the most common reasons for the issue and possible solutions thereto.
Check system time
To begin with, sometimes the issue in question arises when the system time on your Mac is incorrect, or it isn’t synchronized properly with Apple time server. If you noticed that time zone or time is wrong at the top right corner of your Mac screen, do the following to fix the issue:
- Go to the Apple menu and proceed to System Preferences.
- Select Date and Time and tick the box ‘Set Date and Time Automatically’.
- Select the time for your region.
- If this box is already checked, uncheck it and, then, check again. If prompted, type in the administrator login and password.
- Open Time Zone and tick the box with ‘Set Time Zone Automatically using current Location’.
- Close the tab. If time is set properly now, try reinstalling High Sierra on your Mac.
Just wait a little
Another common reason why you may face the issue with the recovery server is simply because Apple servers are too busy responding to thousands of users’ requests at the same time. Don’t worry and try running the update in a few hours.
Make sure your Wi-Fi connection is proper
It also may happen that Wi-Fi connection is not proper and keeps disconnecting. In order to solve the problem, simply try using another Wi-Fi source or connecting via the Ethernet cable. We also recommend you to check if your connection is secure enough; Apple recommends connecting the device via WPA/WPA2 or WPA2-Personal Wi-Fi networks. For example, when using free Wi-Fi at a café or library, Apple servers may reject this connection, and you won’t be able to download some secured files. When at home, you may also apply changes to your Wi-Fi router settings to boost the security.
Check security software on your device
Mac computers are well-known for their built-in security features, that is why Apple frowns upon the installation of various antivirus programs. If you happened to have one on your device, try booting Mac into the safe mode or removing the app at all prior to reinstalling macOS High Sierra. In order to start the device in the safe mode, perform as follows:
- Restart your Mac.
- When turning it on, press and keep the Shift key.
- Hold it until the Apple logo appears.
- Wait for your device to boot.
- Log in to the Administrator account and reinstall the High Sierra update.
We hope the abovementioned steps will help you to fix the issue easily. If you take all the measures, and the issue persists, set up your new administrator account, log in to it, delete the previous High Sierra download from the Applications folder and try downloading and running the installer again. Otherwise, you are free to contact Apple to get proper technical assistance. Good luck!
