Sarah MitchellThe AppleThunderboltNHI assertion strongly implicates a Thunderbolt/USB4 dock firmware incompatibility with Sequoia 15.1’s updated IOThunderboltFamily stack; validate dock firmware via the vendor’s macOS updater and inspect system_profiler SPThunderboltDataType for “Route String” errors indicating link training failures. Boot into macOS Recovery (⌘R) and run diskutil apfs list to verify snapshot integrity—corrupt com.apple.os.update-* snapshots can stall wake via kernel_task deadlocks on the APFS journal. If on Apple Silicon, force a bridgeOS restore via Apple Configurator 2 in DFU mode (right-click DFU → “Restore BridgeOS”) to reset the Thunderbolt controller’s embedded firmware, which is not updated by standard macOS installs.
