Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794691713)

While seemingly orthogonal, a corrupted com.apple.cloudd keychain sync token can deadlock the securityd daemon during wake, blocking the IOPlatformPluginFamily thermal policy evaluation; verify with log show --predicate 'subsystem == "com.apple.securityd"' --last 1h | grep -i "keychain|passkey|authd". Force a local keychain reset via security delete-generic-password -l "iCloud Keychain" -s "com.apple.account" followed by killall -HUP securityd to clear stale Passkey attestation caches that may hold IOService locks. If the panic log shows authd backtraces, disable “Allow this Mac to approve” in System Settings > Apple Account > Password & Security, then re-enable after a full shutdown to reset the Secure Enclave’s SEP firmware handshake state.
