Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794688876)

An incomplete or delta-updated iOS/iPadOS installer staged on the Mac’s APFS volume (often hidden in /Library/Updates or ~/Library/Application Support/Apple/SoftwareUpdate) can trigger mds/mdworker snapshot indexing storms that saturate the IOKit power management semaphores. Boot into macOS Recovery (⌘R), open Terminal, and run diskutil apfs listSnapshots / to purge any stale com.apple.os.update- snapshots consuming metadata space. For USB-C/Thunderbolt dock isolation, use system_profiler SPUSBDataType SPThunderboltDataType in Recovery to verify the dock’s PD controller firmware version against the vendor’s latest; a mismatched PD contract (e.g., 60W vs 96W negotiation) causes the AppleThunderboltNHI to assert kIONotPrivileged during the IOPCIDevice::setPowerState callback. If the panic persists with all* peripherals disconnected, perform a full DFU-mode restore of the BridgeOS (on T2/Apple Silicon) via Apple Configurator 2 to rule out SEP/THC firmware corruption.
