You may need to view the information stored for that certificate in the keychain, and specifically the information that belongs to your signing certificate in Acrobat.įollow this Apple support guidance for your OS to view information in the keychain : Verify if revocation, the trust information, the expiration date, or the certificate's store location changed. If the same problem occurs with new account, then try to see if the problem is corrected by uninstalling and reinstalling Acrobat, or, If this is a personal computer check with the Apple support forums and any release notes related to that patch.Īs far as Acrobat, I would say to create a new user profile account in that computer and test if the same problem manifests with a new user account. If this is happening in government computers try to get support first through your IT support team see if they know of any issues with that patch.
