Thanks for your answer. As I already explained, I did those steps, got the answer suggested, but it did not fix the problem. That it "should have" is clear, but it did not. My ~/Library/Developer folder is empty. What further step is needed, is what I am asking in my post.

Here is what happened: xxx/ % sudo rm -f /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress Password: xxx/ % sudo rm -rf /Library/Caches/com.apple.SoftwareUpdate/* sudo killall -9 softwareupdated zsh: no matches found: /Library/Caches/com.apple.SoftwareUpdate/* killall: warning: kill -kill 555: Operation not permitted xxx/ % softwareupdate -l Software Update Tool Finding available software Software Update found the following new or updated software: Label: Command Line Tools for Xcode 26.4-26.4.1 Title: Command Line Tools for Xcode 26.4, Version: 26.4.1, Size: 920104KiB, Recommended: YES, xxx/ %

This set of steps did not work. I have submitted a Feedback report, but was not given a number I can see, that I can report to you.

Furthermore, Terminal responded that sysdiagnose must be run as root. I don't know how to do that.

Your latest set of commands did not work. I still have the Software Update Available line in System Settings. Please tell me again just what you want me to do at this point.
