OpenCore EFI → macOS Big Sur 11 → macOS Tahoe 26
A refined OpenCore build for one very specific laptop — pure Objective-C tooling, from the first boot to Tahoe. Created and maintained by chris1111.
This EFI is specially designed for the HP EliteBook 840 G4. Do not install this program on another machine — every patch, kext and ACPI table is tuned to this exact hardware.

Main-branch EFI refreshed with the latest kexts and config refinements.
A dedicated Xcode build branch targeting macOS Tahoe 26 lands in the repository.
