Victorvhn Posted September 11, 2020 Share Posted September 11, 2020 Hi, I'm trying to hack a Dell Latitude 3400. But the moment I select 'Install MacOS Catalina', the screen goes black and nothing happens (the pen-drive reading light even turns off). I saw that here on the forum there is an installation topic on that same model, so I think the problem may be me and not the incompatibility. Anyway, I think it is some problem related to BIOS. I tried to follow these settings: , but in my BIOS I don't have the option "Legacy Option ROMS". These are the options I have in the BIOS:https://www.dell.com/support/manuals/us/en/04/latitude-14-3400-laptop/latitude_3400_specs/system-setup?guid=guid-ad1bb6f1-5f1a-40a3-b3c9-b17abc452cba&lang=en-us As I don't have access to a mac to create a bootable USB stick, I downloaded the images from the olarilla forum: Catalina 10.15.6; Catalina 10.15.3; Mojave 2020. And all the images happen the same problem. If anyone knows what it can be, and can help me, I would be grateful! Aida64 Report.rar Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 11, 2020 Moderators Share Posted September 11, 2020 Legacy Option ROMS are for older generation Dell laptops only. You don't need that for your system. Just set to the Default and then only set the following settings: UEFI enabled AHCI enabled Secure Boot disabled Fast Boot disabled 1 Link to comment Share on other sites More sharing options...
Victorvhn Posted September 13, 2020 Author Share Posted September 13, 2020 Hello @Jake Lo. I was able to install macOS Catalina 10.15.6. After installing, I used the folder provided in the post Everything is working correctly (Trackpad, Audio, Network), but the HDMI output is not working. I tried to change the ig-platform-id several times. In these tests sometimes, when HDMI is connected, the machine is restarted. I am attaching the EFI folder that I am currently using as an attachment, and I apologize for being totally layman. Thanks in advance!
