Cataprat

ok I will try. just one more thing, my audio codec is the Realtek ALC256, the sound only appears when I plug in a USB Headset or a JBL GO Bluetooth. The internal Speaker does not appear in the audio output options, I have tried all the layout-ids. I need to do something more. thanks for helping...

After reading the opencore guide several times, I was able to install Big Sur. Everything works fine, but I can't configure 4K @ 60 in my monitor. The maximum resolution I can get is 1440p. what do i need to do to get 4K @ 60? thanks for helping ... follow my EFI and config ... Optiplex_3080_Micro_EFI.zip

updated all kexts to the latest build / commits and apply framebuffer-patch-enable: 01000000 , framebuffer-stolenmem: 00003001 but kernel panic persist.

I moved to version 1.4.9 of Lilu, but received the same kernel panic
