Hi,
I noticed that the new COD Black Ops 7 will require TPM/Secure Boot enabled...
Is there an up to date guide for doing this on Sequoia/Tahoe?
I dual boot, so that will suck if I have to give up playing modern games in Windows in order to keep the hackintosh side working :(

I skim red this https://github.com/profzei/Matebook-X-Pro-2018/wiki/Enable-BIOS-Secure-Boot-with-OpenCore
and it looks rather intimidating and a nightmare to maintain each time you update MacOS :(
I suppose, I could just disable secureboot each time I want to go into MacOS, when it becomes manditory for newer games? Pretty longwinded and annoying though :(

Any links/help would be great!

Thanks!

Unfortunately @Edhawk @Shaneee that boot.efi failed to register in the BIOS :(
I did all the others and that one was last, then it failed to register it grrr!
So I don't think that's the right file that I renamed?
Any ideas guys? I'm so close lol!

When I open my macOS Sequoia drive and use the make files visible keyboard shortcut - 'CMD+shift+.'
Yes the full stop is part of the keyboard shortcut.
On a PC keyboard CMD=left Windows key

I see a boot.efi file in the /usr/standalone/i386 folder, as shown in the screenshot below.

Much larger file size (724kb).

Nice one mate! I've just copied that to USB, I'll try enrolling it now and hope it bloody works now haha! Thanks again!
 
One thing I don't understand, is why was that file not where it should have been, in my freshly created USB installers EFI partition? Pretty strange.

I mean as time goes on, you just disable SecureBoot, install/update MacOS and steal the file from the SSD's folder, then reboot, re-enable SecureBoot and enroll all of the updated efi's again - but it's still a surprising mistake for the guide material?
It was posted on a forum elsewhere just the same as what was written on his GitHub guide, so that's strange it's lacking so much critical information?
