Latitude E7270 Flickering Crazily before Sleep


Recommended Posts

Hello. I have installed Mac OS  Catalina on my dell latitude e7270 touchscreen i7 version. Everything is working good besides when the computer is falling to sleep, first it is flickering crazily before the screen goes black. I have included a video below. I used Jake Lo's bootpack and I'm experiencing this issue. I also tried to reinstall and tried Mojave but still experienced this issue. Any help is appreciated.

Remove these drivers:

SMCHelper.efi from drivers/UEFI

VBoxHfs.efi from drivers/UEFI


Remove VoodooPS2Controller or ApplePS2Controller. Only use one or the other, not both.

Remove either SSDT-UIAC.aml + USBInjectAll.kext or remove USBPorts.kext. Only use one or the other, not both.
