kOSKextReturnTimeout
A kext request timed out
kOSKextReturnTimeout means that a kext request timed out. It does not reveal whether the request was waiting on dependency work, user-space handling, a lifecycle callback, or another stage; the surrounding diagnostics and timing are needed to identify the blocked operation.
Do not confuse this with kOSKextReturnDeferred. Deferred means the kernel posted an asynchronous request to user space; timeout means the request exceeded the time allowed for completion. One status describes scheduling, the other a failure to complete in time.
What makes the timing useful
- Record start time, timeout boundary, operation name, target kext, and the last state transition observed.
- Preserve diagnostics from dependent kexts and user-space components that ran during the same interval.
- Verify whether a modern deployment was waiting for an AuxKC rebuild or reboot-related transition instead of an immediate runtime load.
