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!

No, I disable SecureBoot but leave the native TPM active in the bios for my Hacks. Not had any issues in Windows 11 as I don’t game.

"Not had any issues in Windows 11 as I don’t game." Your a man after my heart Edhawk! Someone who does not care about little kid's games.

Mate, where do I get "/usr/standalone/i386/boot.efi" from? It's not in OpenCores files? It's mentioned in that guide?

Any ideas where this file comes from @Edhawk @Shaneee

From the macOS USB installation drive the guide tells you to create.

You may need to Unhide/make visible the hidden macOS files and folders, in order that it becomes visible when you go to the "/usr/standalone/i386” folder.

@Edhawk Weirdly, in that folder, there isn't the file the guide requests? All that's in there, is 'Secureboot.bundle' ? And I've got the hidden files showing?

In modern macOS the file you're looking for is on the Preboot volume.

Forgive me for being a dumbass lol, but I've used MountEFI to mount the USB installers partitions, and showing all files, there is that folder structure, but it's not in there? Am I looking in the wrong partition then?

On the root of your macOS drive in System/Volumes. Each system has a different path I'm sure as the folder is a hash name but this is where mine is,

/System/Volumes/Preboot/FC998930-32AB-491C-9EB6-B6D0322AB1B2/usr/standalone

OK, so I've opened that folder, and it's full of loads of files but not that file :(
There is loads of files named "boot.efi.j132ap.im4m" etc.
But no boot.efi singluar file :(

So those files are the boot files for T2 machines as far as I'm aware. boot.efi.x86legacyap.im4m is boot.efi. In theory that file renamed to boot.efi is what you're looking for.

Edit:
See here, https://theapplewiki.com/wiki/T2
Those jxxxx file names are the board IDs of T2 Macs.

Thank you mate, I'll try that. I don't know why the guide didn't mention any of this. I hate that about Github people, they miss out so many parts, yet call it a guide!
It's only a 4KB file BTW?

How do you mount and access the Preboot volume?

The boot.efi would be a small file. That is expected.

Not sure why @Perez / @miliuco hasn't explained it better, his guides are usually much clearer and expansive than what he provided on that Github page.
