I deleted these files, and rebooted. My laptop stuck at IOConsoleUser: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0.
So from an usb, in terminal, I recovered files, and the laptop booted.
I Installed macOS Catalina, everything is working fine, except the graphics. System Properties shows 4mb, Night Shift and Airplay not working, no brightness slider in System Preferences - Display.
I have Intel HD Graphics 4400.
Can anyone help please?
