I always thought of it as only being used on Windows, e.g. for VSS and long pathname support.
Are any of you expert enough in the area to offer any thought why macOS is looking for it here?
Sorry to veer off-topic into a different AlphaVSS symptom that I assume can’t be fixed the same way.
Follow-ups can be made directly at topic linked above, or (if it’s going to be long) maybe a new topic.
