This certificate has an invalid issuer : Keychain marks all certificates as "Invalid Issuer" [duplicate]

Question

Keychain shows all the certificates as Invalid in my keychain suddenly, as it working before 2 days and i also check in Developer portal and it shows valid there. It marks each and every certificate in Keychain as "This certificate has invalid issuer" . As message suggesting that it must be problem from issuer side and and our issuer is Apple. So how to fix it ?

Answer 1

In Keychain access, -> View -> Show Expired Certificates, then in your login keychain click on expired certificate and delete it. I also had the same expired certificate in my System keychain, so I deleted it from there too.

-> After deleting the expired cert from the login and System keychains,download certificate from below link and open with keychain.

Download https://developer.apple.com/certificationauthority/AppleWWDRCA.cer and add it to Keychain access > certificates (which expires on 2023)

I found it in the System Keychain, not in the Login keychain. Thanks anyway! – Grovergroves

after installing new wwdrca certificate "This certificate has an invalid issuer" is not gone – Beatup

Once remove certificates which are showing Invalid issuer and try again by installing – Featureless

This was preventing me from submitting to Apple an version... And all Xcode gived me was some non-related error.... Updating AppleWWDRCA on system keychain solved! – Kovar

Worth adding: if you have BOTH the old certificate and the new one, it still may fail, so do remember to delete the old one – Medawar

Need to remove the old one – Featureless

this issue was preventing me from making an enterprise build to export, never did Xcode say that this was the issue. I happened to notice the red text, used this fix, and voila...! – Presidium

If I remove certificates they just auto-reappar. – Bridoon

@Bridoon if that is the case, then you are probably removing them from Login keychain and not the System one. I noticed the same behavior if I didn't delete from the System keychain. – Mack

This got rid of the "invalid issuer" problems. Searched "devel" and deleted anything expired. This didn't solve my problem of not being able to deploy a test build to my phone. When is Apple going to finally make it easy to run my own code on my own phone? – Afterdamp
