hi bro, I just made a copy of macOS Ventura installation disk using your EFI, but with no luck, it doesn't show anything upon booting. Should I do something to make it work? am currently using Montery on my machine. It's a i5-7200u model. Thanks for any help!!

Maybe you should check your BIOS and make some changes.

Thanks but it’s just the same. i’ve reset the bios settings to the default one and made changes as you mentioned, but it’s just black again. Have you not experienced this before??

Just to report back, I got able to enter into boot picker screen after changing Opencore files from your EFI files to the newly downloaded opencore files (0.9.8 version). But as soon as I tried to boot from any drive at the boot picker, it just stopped dead. Perhaps using same opencore files caused trouble in my machine. Now I would have to find how to get it work after boot picker screen.

mmmmmm which distro are you using?. I´ve only tested it with Ventura. Have you tried with another usb port or usb stick? I supose you have formated the usb stick the right way because got into boot picker screen so.. i dont know man. Maybe you need to map your usb ports or something like that! keep in touch

Ventura, as well. Using another usb stick, haven't tried. But I doubt it would ever matter. Changing Bootx64.efi and OpenCore.efi made me see the boot picker screen, now I'm trying to run debug mode, wishing it finds out something, anything. Thanks anyway!!

Sorry to hear that man. If you get some logs and want to share them, i´ll be here. Good luck!!

About USB... I've had some problems similar to yours in the past. And some of them were 'fixed' just by trying them on different hardware.
