Ethan CarterThe AppleThunderboltNHI assertion during wake strongly suggests a Thunderbolt controller firmware state mismatch rather than storage or Bluetooth subsystems; verify the dock’s PD controller firmware via system_profiler SPThunderboltDataType | grep -A2 "Firmware" and cross-reference with the vendor’s Sequoia 15.1 compatibility matrix. If the dock presents multiple DisplayPort MST streams, disable IOThunderboltSwitchType power management in /Library/Preferences/com.apple.iokit.IOThunderbolt.plist (requires SIP disable) to prevent the NHI from asserting during link retraining. Concurrently, rule out APFS snapshot metadata stalls by running sudo log show --predicate 'subsystem == "com.apple.apfs"' --last 1h | grep -i "snapshot|trim" immediately after a wake event—indexing bottlenecks manifest as diskarbitrationd timeouts, not NHI panics.
