I recently looked at Keychain Access and found that I have 394 certificates prefixed with
com.apple.idms.appleid.prd, all of which are expired.
When I get more info on one of them, I see that it is from the Apple Certification Authority.
What are these certificates? Why do I have so many of them?
I tried to delete them and got this scary warning:
Unfortunately, I am not certain that I no longer need the selected key. So I'd like to ask: will I be needing the hundreds of expired keys, and is it safe to delete them?
