Owen ParkerIrrelevant to this panic signature. Liquid detection triggers AppleSMC/ApplePMGR alerts, not AppleThunderboltNHI link-layer assertions. Action: This panic maps to Sequoia 15.1’s known regression in IOThunderboltFamily handling of DisplayPort Alt Mode MST hubs during S0ix exit. CLI: Capture a full panic dump via sudo nvram boot-args="keepsyms=1 -zp -v" and inspect Backtrace for IOThunderboltNHI::completePowerStateChange. Hardware Recovery: Update dock firmware (CalDigit/OWC/Belkin sites). If persistent, disable TBT security temporarily: csrutil authenticated-root disable (Recovery OS) -> nvram boot-args="tbtdisable=1" to isolate NHI vs. DP MST logic.
