macOS Sequoia 15.8.2 — Dell G3 3579

OpenCore configuration for macOS Sequoia 15.8.2 (24H232) on the Dell G3 3579.

• OpenCore: 1.0.9 RELEASE (REL-109-2026-11-08)
• SMBIOS: MacBookPro15,2 (sample identity — replace with your own for Apple services)
• Status: boot-tested on this laptop under macOS 15.8.2 (24H232) with OpenCore 1.0.9 RELEASE; SD reader, webcam (including its activity LED), microphone and lid sleep/wake verified working. Brightness keys are the main remaining limitation — see known issues.
• Tested vs. shipped config: the boot-tested EFI has Misc → Debug disabled. This repository's copy is otherwise identical — same binaries, kexts and ACPI — but still carries the original debug flags, which are inert in a RELEASE build.

This EFI is macOS-only: on a multiboot machine, keep the existing Microsoft/ and vendor folders on your live EFI partition.

How Sequoia differs from Sonoma

• Backlight boot argument: Sequoia needs -igfxblr; -igfxblt (used on Sonoma) leaves the panel black. See display backlight.
• Wi-Fi kext build: AirportItlwm 2.4.0 instead of 2.3.0.
• USB map required: Bluetooth does not enumerate without it. On Sonoma this is optional.
• Everything else (ACPI, kext stack, framebuffer, audio layout) matches Sonoma.

Key boot arguments

-igfxblr -cdfon -btlfxallowanyaddr -ibtallowanyaddr

Before you boot
