Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794700870)

[Owen Parker]

Inspect the Unified Log for AppleThunderboltNHI::handleInterrupt spikes correlated with thermalmonitord assertions using log show --predicate 'subsystem == "com.apple.iokit.IOThunderboltFamily" OR process == "thermalmonitord"' --last 1h. A faulty dock PD controller can negotiate an invalid contract (e.g., 20V/5A on a 100W port) causing the NHI to assert during the thermal pressure wake path. Run ioreg -r -c AppleThunderboltNHI | grep -i "current|voltage|power" immediately after wake to catch transient over-current flags before the watchdog fires.
