Rachel KimThe AppleThunderboltNHI assertion during wake often correlates with a WindowServer crash triggered by Safari’s WebKit GPU process failing to relinquish the display link when an external DP dock re-enumerates. Verify if WindowServer CPU spikes precede the panic by running log show --predicate 'process == "WindowServer" and eventMessage contains "GPU"' --last 24h and cross-reference the timestamp with paniclog. Mitigate by removing all login items launching browser helpers (launchctl list | grep -i safari) and forcing discrete GPU usage via sudo pmset -a gpuswitch 2 to stabilize the Thunderbolt display handshake.
