Symptom
On macOS, every update started from the Desktop app's Update button fails with exit code 2, and the app keeps retrying every few minutes.
Evidence what you'll see
- Error: Another Hermes update is already running (started a few seconds ago, process <pid>)
- The PID in the error belongs to the helper the same update just started
- Running hermes update from a terminal with the Desktop app closed works
Cause
The update lock recorded the hand-off helper as its owner, but hermes update didn't recognize that helper as part of its own update, so it refused the lock.
