@lifjoy Tried that too, but no luck. At the end I "resolve" by fresh install the macos w/o any time machine recovery.. @JasonTran Sadly I couldn't solve mine... u may try @lifjoy method... mine abit extreme... fresh install everything as I only use that imac for development... not much data/app inside, redoing everything not that time consuming for me
