So, thanks for all help you are giving. I tried a fresh install from Big Sur with the recovery image. It initialize and installs successfully, at least the first part, but when it restart for the first time to continue the installation, it just restart the computer, after I`m select ``macOS install`` in OpenCore. I don`t have much of knowledge with ACPI and those things, so if you could help me, I`ll be glad. PS. All those files in ACPI folder I used in previous install for fix some problems with audio, USB, etc. EFI.tar.gz

Hi; Every time I start a video call in any app like Telegram or WhatsApp, the entire system crash, that I even need to restart the entire hardware. I have no idea to what to do or what is causing this. If anyone could help me, I'll be glad. This is my EFI folder if you want to take a look. My hardware: Intel i5 4300U. 8GB RAM. Intel HD 4400. Sorry for my bad English, that's not my native language. EFI.zip

Yeah, I let it booting all the night, and it worked. Thanks for the help.

Hey, how are you ? First of all, sorry for bad english, it's not my native language. It is possible to run Big Sur on Dell E5440? I tried several times but I couldn't successfully install the OS. I have successfully installed Catalina, but not Big Sur. I've tried an clean OpenCore install, from the beginning. It boot in OpenCore, It even go to the installation screen, but, when it restar for the first time, it show the Apple logo with progress bar, and sticks on it. It even show above the progress bar "About xx minutos remaining", the minutes goes down, but the progress bar still the same. I saw this guy, with the same model as mine, that he has successfully, so I thought that my model is compatible. I tried his EFI folder, but didn't worked. Tried many EFI that I found here, but no luck. My specs: Dell Latitude E5440 Intel core i5 4200U 8GBRAM Intel Hd Graphics 4400 EFI.tar.gz

OMG, everything is working, including the USB. Thank you so much for your help.

Hey, first of all, English is not my native langue, so sorry for any errors. I have successfully installed Catalina in my Dell E5440 with OpenCore, but the USB and Audio doesn't work, and the TouchPad kinda works, but it is very slow, and in system it doesn't recognize as Touchpad, but as a normal mouse, gesturs doesn't work either. Can someone help me please? EFI.zip
