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

[Hannah Brooks]

Check pmset -g log | grep -e "Wake Requests" -e "DarkWake" -e "Kernel Client Acks" for the 30 seconds preceding the panic timestamp; look for ARPT (Wi-Fi) or XHC (USB) clients blocking the transition, which often masquerades as a Thunderbolt NHI timeout. If an external DisplayPort dock presents a USB billboard device or hub, it may be failing IOUSBHostInterface::setPowerState during the DarkWake to FullWake handoff. Disable “Wake for network access” (sudo pmset -a wom 0) and test with a direct DP-to-USB-C cable bypassing the dock’s hub controller.
