Hi, I'm getting error 65 upon stapling and I am suspecting that non-default trust settings may be the reason as outlined here: Unfortunately whatever I do, I can't seem to reset the trust settings to their default values (removing the blue/white "+"), I'm not being asked for credentials upon closing the certificate window. I have also tried to unlock the System Roots key chain, to no avail. Also, when running security dump-trust-settings -d I get Number of trust settings : 0 for all certificates. Any ideas as to what I may be doing wrong? Is there any other setting that may be involved? Thanks!
