Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794703853)

While unrelated to the IOPlatformPluginFamily panic signature, ensure your Apple Account security posture isn’t introducing background accountsdd or akd daemon contention during wake by auditing log show --predicate 'subsystem == "com.apple.accounts"' for kTCCErrorPolicyDenied spikes coinciding with the panic timestamps. Rotate the local device keychain sync identity via security delete-generic-password -l "iCloud Keychain" followed by a forced akd restart (launchctl kickstart -k gui/$(id -u)/com.apple.akd) to clear potential Secure Enclave nonce desynchronization that can manifest as watchdog timeouts if the T2/SEP handshake stalls during power state restoration. Confirm Passkey attestation certificates are valid (security find-certificate -c "Apple Passkey" -p) as expired roots rarely cause kernel panics but frequently stall userland resume completion.
