Fresh High Sierra no updates

[Rimmsi]

Hi, I did a clean install of High Sierra on my Macbook Pro 15" Mid 2015. After installation, I ran the App Store to install updates, but the system doesn't find anything updates. I tried reinstalling the system, but always with the same result. Do you know if Apple has limited support for older MacOS? Thank you.

Yes, but the App Store does not offer their download, incl. updating Safari and the App Store itself as before.

There seems to be a problem with updates on High Sierra. I have a virtual machine and it’s also showing no updates. I’m almost certain I left some the last time I used it. https://forums.macrumors.com/threads/itunes-software-updates.2416893/

You should contact Apple Support, they might have blocked it by mistake due to recent vulnerabilities discovered in curl and other open source utilities included in macOS.
