Hello everyone Please help me I can not install Big Sur My device Intel (R) Core (TM) i5-8250U CPU @ 1.60 GHz[Cores 4] [Logical processors 8] 8 GB RAM, 4K Touch.
Can you lay out a working EFI? Please
4K Touch????
no it didn't work out4K Touch
Did you install it successfully? I think it should be the problem of 4K touch screen. I also started the black screen, and then I couldn't install it.
First, unlock the CFG, then adjust the DVMT.no it didn't work out
Thanks. I'll try it now and answer right away. By the way, I also have a Catalina keyboard that doesn't work after sleep.First, unlock the CFG, then adjust the DVMT.
At present, there are some problems in my EFI: after waking up the computer after sleep, there is a certain probability that the keyboard can not be operated, and the shortcut key for brightness adjustment is abnormal.
