On Big Sur, trustd is in Apple's "ContentFilterExclusionList" ....meaning firewalls can't block it! 😭 Welcome to the future? 😱
Hey Apple users: If you're now experiencing hangs launching apps on the Mac, I figured out the problem using Little Snitch. It's trustd connecting to ocsp.apple.com Denying that connection fixes it, because OCSP is a soft failure. (Disconnect internet also fixes.)
