macOs Big Sur on Dell Optiplex 3080 Micro

Anybody got working sleep? Or this problem is unsolvable?

sleep works fine with a posted disk, but I have another problem. I can't upgrade to Monterey. I get an apple and a black screen. Any ideas?

Check what the verbose output tells you.

I can't understand it. Big Sur starts normally, but when I try to install Monterey, it goes into reboot, then the big sur is loaded again

Check wifi kext. There are different versions for BigSur, Monterey and Ventura.

When I upgraded to to Ventura, the system was hanging during load.

But still unlikely - my system at least upgraded successfuly.


Did your system reset properly? Or you still have reboot problem?

Btw, I finally fixed problem with sleep and now in my 3080 everything works. And yes, everything.
WiFi, usb3, sleep, and so on.

I just disabled sleep in BIOS. My PC doesn't sleep, but power consumption is insignificant, so it's just almost as good as real sleep for me. Monitors are going off and on again without issues.

If someone still struggles, I can attach my EFI later, when I'll return homr. But you need to fix cfg lock or/and dvmt to get rid of reboot problem.

@phanex, please post EFI and state OC version.

The site didn't work so I wasn't able to post. Hopefully it will last until I will be home. I'll attach this evening if will be lucky.
