Dell Inspiron 7567: Blinking screen on 10.15.7 installation

Hello. I am experiencing a problem with my Catalina vanilla installation.

My Dell 7567's screen is constantly blinking. This started in the installer and persisted after successful installation. Apart from the mentioned, the system is working perfectly fine.

I am able to disable the backlight completely by pressing F11/brightness down button. I am barely able to see the on-screen text using a desk lamp afterwards.

I have tried installing AppleBacklightFixup.kext, Lilu.kext and WhateverGreen.kext and setting my SMBIOS to iMac18,1 but none of those proposed solutions have helped me so far.

To illustrate the problem, I have recorded a video (link) of my laptop booting into the installer and then shutting down. I have also included my CLOVER folder.


I would appreciate any help or advice.


Best regards, Luka

Thank you for answering. Sorry, I believed that stating my laptop model was enough. Here are the specs:

CPU: Intel Core i5-7300HQ @ 2.50 GHz

GPUs: Intel HD Graphics 630 - nVidia GeForce GTX 1050 (unusable)


I'll try to fix the errors you have pointed out and will reply.


Best regards, Luka

I have done the following:

  • Removed FakeSMC.kext so there is only VirtualSMC.kext left;
  • Removed WhateverGreen.kext;
  • Used complete MacBookPro13,1 SMBIOS from Clover Configurator;
  • I am now using the ACPI/patched folder from here;
  • Changed model, device-id and ig-platform-id for Intel HD Graphics 630.

But now I unfortunately cannot boot the system from SSD as the boot process gets stuck on "BuildActDeviceEntry exit" (see picture).

I also had attached my CLOVER folder with changes.


Thanks for your help.

Regards, Luka
