Issue: How to fix "Unable to check for updates. Can't connect to the Software Update server" on Mac?
Hello. I tried to update macOS but I received a message “Unable to check for updates. Can't connect to the Software Update server.” What should I do?
Solved Answer
MacOS is a Unix[1] operating system developed by Apple Inc. in 2001. It is the primary operating system for Apple's Mac computers. It is the second most widely used desktop OS, after Microsoft Windows. Just like any other operating system, macOS should be regularly updated to keep it stable, and secure.[2]
People can use Software Update to install updates and upgrades for macOS and its built-in apps, including Safari. However, sometimes people run into issues when trying to do so. People report trying to update their macOS but failing to connect to the update server. Additionally, they see “Unable to check for updates. Can't connect to the Software Update server” error message.
It is unknown what exactly could cause this. There is a possibility that some users modified an OS file to disable OS update notifications. However, such a modification also disables users' abilities to manually update the operating system. Such a problem could also arise because of corrupted system files.[3]
In this guide, you will find 3 steps that should help you fix “Unable to check for updates. Can't connect to the Software Update server” on Mac. Proceed with the step-by-step instructions below carefully.
Method 1. Install Updates through the Terminal
- Click the Launchpad icon in the Dock, type Terminal in the search field, then click Terminal
- Enter the following command:
softwareupdate –fetch-full-installer –full-installer-version 11.7
- Instead of full-installer-version 11.7 enter the version you want to update
Method 2. Run Terminal Commands
- Click the Launchpad icon in the Dock, type Terminal in the search field, then click Terminal
- Enter the command below:
softwareupdate –list-full-installers
- Choose the version you want to install from the list and run the following command:
softwareupdate –fetch-full-installer –full-installer-version 11.6.2
- Instead of full-installer-version 11.6.2 enter the version you want to install
- Launch the new application in the Applications folder
- Run the following command:
Title: macOS Big Sur, Version: 11.7, Size: 12118755KiB, Build: 20G817
Method 3. Reinstall macOS
If the previous steps did not help you fix the issue, try to reinstall macOS. The following steps will help you do that through Recovery which should keep your files and apps. However, we always recommend backing up your data before proceeding with the reinstallation.
- Boot your Mac into macOS Recovery. On Intel-based Macs, that means holding down the Cmd + R keys during startup until you see the Apple logo. If you use an Apple silicon Mac, hold down the Power button while turning it on and select Options, then Continue on the Startup Options screen
- Select an administrator account (if your Mac prompts you to) and enter its password to load the macOS Recovery menu
- Select Reinstall macOS [Version Name] and Continue
- Agree to Apple’s software license terms
- Select your Mac’s startup drive, for example, Macintosh HD, and select Continue
- Wait for your Mac to finish reinstalling macOS
- The process could take an hour or more. Your Mac will reboot multiple times in the meantime.

Tools that you can use to fix your error are listed bellow:
Access geo-restricted video content with a VPN
Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.
Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
