Emily HartA corrupted Auto Unlock handshake between the Mac and Apple Watch can stall the IOPlatformPluginFamily power state transition during wake, manifesting as a Thunderbolt NHI assertion timeout. Verify the secure element synchronization status via log show --predicate 'subsystem == "com.apple.bluetooth"' --last 1h | grep -i "autounlock|handoff" and remove/re-pair the Watch in System Settings > Touch ID & Password > Apple Watch to clear stale encryption keys. Concurrently, ensure the Mac’s battery health (System Information > Power) isn’t reporting “Service Recommended,” as gas gauge inaccuracies trigger aggressive AppleThrottle interventions that conflict with TBT retimer firmware. If Stage Manager was active on an external iPad via Sidecar, disconnect it before sleep; the WindowServer context preservation across the USB-C/Thunderbolt link frequently deadlocks the NHI controller during dark wake.
