Using Catalina 10.15.7 on a MacBook Pro 13". Whenever I launch Keychain access, I get the same error when trying to search for a keychain. See attached screenshot:
Would love some advice on how to fix this. Thanks in advance..!
The same for me!!
Since some versions of macOS (I think Monterey or earlier!).
I have a thread network with ~90 HomeKit-devices (from Eve Systems) and think it has to do with that. My thread network is extremely unstable, so I came to the Keychain Problem with my analysis …
Do you also have a thread network? (A HomePod mini, HomePod 2. generation or AppleTV 4K (or newer) are sufficient to have a thread network.)
Apple Care is not able to solve :(
An extra piece of new info. It turns out the unexpected errors are specific to one kind of keychain called, "Preferred Thread network Record". These items take the same name as the regular keychain item.
For example, I have one keychain for my router, with the name "Router", and the kind is "AirPort network password" . There are three more items with the same name (Router) that are all 'preferred thread network record' kind of keychains. Selecting any of those pops up the "unexpected error".
If one of those exists for a keychain, and I search that keychain, I'll also get the error, as if I had selected the "preferred thread" version. I get a couple of different error details for those.
Otherwise, I don't get the error. Those 'network Record' keychains are sprinkled throughout my keychain list. I don't know where they came from, but something isn't right.
Any ideas? Thanks in advance!
Same happens to me on macOS Ventura 13.3.
Only with records with Kind : Preferred Thread Network Record
