So they clicked ‘try tonight’ in the dialog asking ‘Updates Available - Do you want to restart to install now or try tonight?’. And then macOS did just that. I don’t quite see how that isn’t user-initiated.<p>Why would they have ‘Download new updates when available’ enabled when they were not planning on installing these updates? I assume that having that enabled causes that dialog to appear in the first place.
I am sorry to hear this, however I would not be surprised if someone in the OpenCore/Hackintosh space has (or will produce) a fix, because those systems are sometimes particularly sensitive to updates
