That mac update deleted everything or missing files after mac update is the worst problem that's ever happened. It has been solved if you follow my steps-by-steps guide. Another formidable problem is the new macOS Mojave 10.14 doesn’t suit you at all. You prefer the previous system macOS High Sierra. In such case, we would recommend you to downgrade macOS Mojave.
