Hi, I successfully installed MacOS Sequoia with EFI attached. Graphics, sound, Internet work.
I would like to install MacOS Tahoe, but EFI won't allow installation.
Does anyone have EFI Tahoe for Intel HD 530 please?

I think the reason why Tahoe cannot be installed is that the SMBIOS used is no longer supported by Tahoe. Switching to an SMBIOS that is still supported should be enough. Alternatively, you can also insert the patch to disable the board serial number check into the Config.plist. You can find it in the Tahoe collection thread here in the forum.

But you should also update your OpenCore & Kexte to the latest version. Everything else you need to know before & after the update can be found in the thread linked above.
