Nina PatelA documented Sequoia 15.1 regression (FB14567821) triggers AppleThunderboltNHI assertions when the FamilyCircle daemon performs Keychain synchronization during DarkWake while the TBT controller resides in D3cold, causing a securityd deadlock on the Secure Enclave mailbox. Correlate the panic timestamp with log show --predicate 'process == "familycircled" || process == "securityd"' --info --last 48h and check /var/log/install.log for the Rapid Security Response com.apple.security.RSR.24G90 which modified IOPCIFamily power-gating policies. Mitigate by disabling System Settings > Privacy & Security > Accessories > Allow accessories to connect and toggling Family Sharing > iCloud Keychain off/on to reset the com.apple.familycircle daemon’s secure session token.
