Hi, I'm trying to do fresh install of BigSur on My Dell Inspiron 7537. Using Clover EFI Bootloader to create the bootable USB. But as soon I select the install volume from boot screen getting Error as shown in the screenshot. What am I doing wrong here.
I have successfully installed High Sierra on my Dell Inspiron 7537 having intel HD4400. But using certain apps like Chrome or Intellij I'm seeing screen flickering and distorting in graphics particularly on images. Have attached few images. Anyone can you please help.
Thanks Rehabman! Removing ACPIBacklight.kext fixed the issue.
But I have been facing graphics glitch or image graphic distorted while using certain apps or Chrome browser. It happening only on internal monitor.
Attaching screen shot, anything am I missing here
Rehabman After following the guide I was able to get the slider appearing in System Display preference but the brightness is not changing but stays the same. I'm on HD4400 Haswell on 10.13.5.
