Updates to macOS repeatedly fail with this error:
The text reads:
The update package has been
deleted since being downloaded
from the Apple Software Update
I don’t know what would be deleting the update package, as the error states. It feels as though the downloaded package is corrupted somehow, but the update doesn’t know how to clear the cache and start over.
How do I clear update-related caches, or what do I need to do to clear this broken state and get the system update to work again? Restarting doesn’t help.
