vamose Posted December 30, 2025 Share Posted December 30, 2025 Updated to 26.2, all went well. I log onto the Mac, start working on any app, and after about 10 mins (time varies), screen goes blank. nothing happens. The only option is to restart. I have tried to reinstall the OS, also updated open core, no benefit. Any help is appreciated.

vamose Posted December 30, 2025 Author Share Posted December 30, 2025 No, I am using the machine normally, say powerpoint, and all of a sudden it goes blank, dark. Keyboard is not operational, as caps lock does not light up.

With this Lilu fix, there are no changes needed for WhateverGreen.kext".
