Check if the network connection is normal

- If a proxy is used, temporarily close it to see if there is any improvement
Sometimes restarting the router or switching the network (such as switching from a company network to a home network) can solve the problem.
Reset the software update cache
The system will cache temporary files when trying to download updates. If these files are corrupted or downloaded, it will cause loading failure.

You can manually clear these caches through the terminal:
- Open Terminal
- Enter the following command and press Enter:
sudo softwareupdate --clear-catalog
- Enter again:
sudo rm -rf /Library/Updates/
After execution, restart the computer, then open "System Preferences → Software Update" and check for updates again.
Use the terminal to manually check for updates
Sometimes the graphical interface displays an error, but the update information can be obtained normally in the terminal.
Open the terminal and run the following commands:
-
sudo softwareupdate --list
Check if there are any updates available -
sudo softwareupdate --fetch-full-installer
(optional)
Force download the complete installation package -
sudo softwareupdate --install
Replacewith the name of the update item to be installed
This method skips some graphical interface flow and sometimes bypasses errors.
Is it common to create new users to test
If you have tried many methods before and haven't solved it, you can create a new user account and try to see if the error is still reported:
- Go to "System Settings → Users and Groups"
- Add a standard user
- Log out of the current account, log in with the new account and check for updates again
If there is no problem with the new account, it means that there is a problem with the configuration or permissions of the original account, and further troubleshooting of the permission settings or configuration files may be required.
Basically these common solutions. In most cases, it can be done by cleaning the cache or changing the network environment. If it doesn't work, it may be a problem with the Apple server side. You can wait for a while and try again.
