I have a MacBook 2019 and when I am trying to install macOS Ventura I get the following error immediately before the download starts:
Installation failed
An error occurred while installing the selected updates.
After checking install.log (available at About this Mac / System report / Software / Logs) I can see that the download fails with the following error:
Failed Software Update - Refusing invalid certificate from host: swcdn.apple.com
I have also tried running the softwareupdate tool with no luck:
➜ softwareupdate -l
Software Update Tool
Finding available software
The operation couldn't be completed. (NSURLErrorDomain error -1012.)
This generates a similar certificate error for a different URL:
Failed Software Update - Refusing invalid certificate from host: swscan.apple.com
Opening the specific URLs in the browser shows me they have a valid certificate. As a last effort, I did update the root certificate to be always trusted but this did not help either.
The time is correctly set on my machine.
Have anyone experienced a similar issue? What can be the solution?
