Attached for download my universal opencore EFI-Folder for all recent versions of macOS (also works with Sequoia and Tahoe). This EFI is especially designed for the X299 community and all my former followers, however, with a few changes, it might be also?applicable for other more recent builds and SMBIOS Versions?different from SMBIOS macPro7,1. In case of questions or issues just leave your comment below.

?

Please?add/delete or enable/disable all system specific kexts for your build in EFI/OCI/Kexts and config.plist -> Kernel -> Add .

?

Disable Whatevergreen.kext for booting the Tahoe installers. There is an additional option of?NootRX.kext implemented, to boot the Tahoe installers if deemed necessary. ? In any case, with SMBIOS macPro7,1, none of these kexts are required, if your GPU is supported by Apple.??

?

As an already implemented option, you can choose between IntelLucy.kext or SmallTreeIntel8259x.kext by enabling/disabling the latter in config.plist -> Kernel -> Add. Small-Tree: SmallTreeIntel8259x.kext works flawless up to Sequoia. For Tahoe only use SmallTreeIntel8259x-KGP-Tahoe.kext of this EFI-Folder distribution although you might still witness KPs. IntelLucy: Successfully tested with direct NIC -> router LAN connection as well as with my MikroTik CRS309 switch with H!Fiber Marvel 113C SFP+ RJ45 (30m) and MikroTik S+RJ10 transceivers. No way to get IntelLucy work with my former Netgear ProSafe XS508M switch! ?Also no way to get Apple's native DEXT Drivers work due to the missing IOMMU implementation of the X550-AT2 NICs of the ASUS X299 Sage 10G.

?

Else, just complete your SMBIOS credentials with Opencore Configurator (OCC) and use your own USB-Mapping-Kext before booting with this EFI. If you don't have any, follow my?XHC USB Kext Creation Guideline?(sorry, this guideline is not in any other forum).

?

For the adaptation of SSDTs and ACPI-patches in EFI/OC/ACPI, config.plist->ACPI -> Add?and config.plist->ACPI -> Patch (by default everything disabled), see my else partly outdated?installation guide?for Mojave. Important note: If you do not adopt and enable?SSDT-X299-HDEF.aml, add bootarg "alcid=2" or the layout-id you need for your onboard sound chip. The boot args are in NVRAM -> UUID ->?7C436110-AB2A-4BBB-A880-FE41995C9F82 -> boot-args. Otherwise AppleALC.kext won't inject. ?

?

Good luck!??
