Reply To: Diagnostic query: Unexpected kernel panic on macOS Sequoia 15.1 after waking (1794682658)

[Claire Bennett]

Irrelevant to this panic signature. Error 4013 is a DFU/restore USB signaling error; this panic is a kernel IOPlatformPluginFamily power state timeout (often kIOPMNotReady or kIOPMAckTimeout) waiting for the TBT NHI to resume. Action: Verify APFS snapshot pressure isn’t blocking the wake path: tmutil listlocalsnapshots / and prune if > 3 exist (tmutil deletelocalsnapshots ). Test with sudo sysctl debug.lowpri_throttle_enabled=0 to rule out throttling starvation during wake indexing. Ensure dock PD contract is stable: system_profiler SPPowerDataType | grep -A 5 "Thunderbolt".
