In the process of updating several Apple devices to OS 27.0.1, I accidentally updated my main workstation from Sequoia to Golden Gate. I had intended to do this, but not this soon. Now I find that the Keychain Access App no longer takes my login password to unlock items. Unfortunately, the Passwords App does not allow me to see a number of things that are stored in the Keychain Access App: e.g. Secure Notes. But in this case the problem is an application password for an IRC client. I have no way of recovering my IRC account unless I can supply the password to Keychain Access.

In https://developer.apple.com/forums/thread/650369 I see that the softwareudpate --ignore flag deprecated in Big Sur and above. So now I get offered four versions of the Command Line Tools by Big Sur: Software Update found the following new or updated software: Label: Command Line Tools for Xcode-12.4 Title: Command Line Tools for Xcode, Version: 12.4, Size: 440392K, Recommended: YES,  Label: Command Line Tools for Xcode-13.2 Title: Command Line Tools for Xcode, Version: 13.2, Size: 577329K, Recommended: YES,  Label: Command Line Tools for Xcode-12.5 Title: Command Line Tools for Xcode, Version: 12.5, Size: 470966K, Recommended: YES,  Label: Command Line Tools for Xcode-12.5 Title: Command Line Tools for Xcode, Version: 12.5, Size: 470820K, Recommended: YES,  I no longer can hide/get rid of those for Xcode 12.x. This is not good! P.S. I installed "Command Line Tools for Xcode-13.2" twice, but softwareudpate is still showing it as available.
