macOS Ventura on Dell XPS 17 L702x Optimus

[mackyreddy]

Intel HD 3000 Graphics Acceleration has been enabled by Open Core Legacy Patcher team but with lots of menu bar & settings app glitches. Lets wait for a stable release, as this one is a nightly release.

All done updated first post with a new installation guide along with all files required for smooth running of macOS Ventura.

 

cheers have a great day

I have dell 702x 3d and i cannot enable hd3000. I make the installation fine but it only recognize the nvidia gt 555m.

Is there any solution to enable hd3000.

Thanks in advance

xps l702x 3d has only nvidia gt 555m, it doesnt has intel hd 3000.

 

better follow the thread related to your laptop in ton*mac*86

Hi, @mackyreddy,

 

thanks for all the work.

 

Mine screen is 1600x900,I just tried your latest 0.9.1 version.

 

added the driver BiosVideo,efi and changed UEFI-output to max and leave blank in the field of resolution.

 

Now boots up the USB normally,but after choosing Install, after some verbose lines( I turen it on),then it reboots.

the last one is like the

CPU i7-2630QM,1600x900.Captain Kasar's unlocked bios, SATA-AHCI, UEFI boot enable,legacy boot disabled,pre-allocate-DVMT-128MB,

what other critical settings? Shall I flash a more customized bios like this one? 

 

Need your help,thanks.

Hi there,

I came across your post from 2023 about the Dell XPS 17 L702X 3D — interesting to see someone else working on the same rare 3D variant!

I wanted to follow up because I've recently picked up my own L702X 3D again after it sat in storage for years.

 

Back then I was running macOS 10.9 Mavericks + Clover, and I'm now in the process of upgrading it all the way to macOS Ventura 13.7.8 + OpenCore.

The machine is going to be a programming learning laptop for my son, so I need reasonably modern app support — that's why I'm skipping the entire 10.x line and pushing straight to Ventura.

 

I actually have some positive progress to share since I last checked: on Ventura 13.7.8,

I've managed to get the display running at 1600×900 resolution, up from the default 800×600 @ 1MB VRAM right after installation.

It's now showing 5MB VRAM with basic framebuffer output — no acceleration of course (Fermi has zero Metal/QE-CI on Ventura), but the desktop is usable for coding, SSH, and light tasks.

 

I read that you couldn't enable the Intel HD 3000 on your 3D unit,

which matches what I understand about the hardware — the 3D variant has the display hard-wired directly to the GT 555M with no Optimus,

so the iGPU is disabled at the BIOS/mux level. That part hasn't changed.

 

Since you were working on this in 2023, I'd love to compare notes.

Could you please clarify a few things when you have a moment?

1. GT 555M status on Ventura: Were you able to get the GT 555M recognized with the correct VRAM size (e.g. 3 GB), or was it stuck at a small value like 5 MB / 256 MB with no acceleration?

2. Which Ventura build?: Which exact macOS Ventura version were you running back then? (e.g. 13.4, 13.5, or something else?)

3. EFI & ACPI sharing: If you still have it, would you be willing to share your EFI folder and any ACPI patches (DSDT/SSDT) you used? Even if HD 3000 couldn't be enabled, your GT 555M configuration from 2023 might give me useful pointers for my current OpenCore setup.

 

Thanks in advance for any info you can share — and good luck with whatever you're running on your L702X these days!

Update: Ventura 13.7.8 display progress on Dell XPS L702X 3D (GT 555M only) — and why I’m moving to High Sierra 10.13.6

Quick note first: my machine is the XPS L702X 3D, not the Optimus L702X. On the 3D model the Intel HD 3000 is factory-disabled; only the NVIDIA GeForce GT 555M drives the internal panel and HDMI. So there is no iGPU fallback path.

Display progression on Ventura 13.7.8 (OpenCore 1.0.7)

I did get a usable desktop, but only in stages:

1. 800×600 @ ~1 MB
   Basic/VESA-style output (typically with nv_disable=1 / no real NVIDIA framebuffer stack). Bootable, but almost unusable.

2. 1280×1024 @ ~5 MB
   Intermediate framebuffer-ish state — better than 800×600, still wrong timings / limited VRAM reporting, not a daily driver.

3. 1920×1080 @ 3 GB
   With the NVIDIA Web Driver framebuffer stack loaded (NVDAStartupWeb + NVDAResmanWeb + NVDAGF100HalWeb) and the accelerator (GeForceWeb.kext) kept out, I finally got a stable native 1920×1080 desktop, correct EDID / panel mode, and About This Mac reporting the GT 555M with 3 GB VRAM.

So yes: full native resolution on Ventura is possible on this Fermi laptop — but that is not the same as GPU acceleration.

Important: no GPU acceleration on Ventura

Even at 1920×1080@3GB, WindowServer was still doing software compositing (very high CPU on WindowServer, laggy UI, poor daily UX). This is the key reminder for anyone chasing “working graphics” on Ventura with GT 555M:

Native resolution ≠ Metal/OpenGL acceleration.
Framebuffer-only = picture looks right; UI still feels like molasses.

Why acceleration failed (what we actually verified)

I tried the OCLP / Web Drivers route seriously (SSH diagnostics during white/garbled screens, AuxKC rebuilds, WEG flags, npci=0x2000, BAR placement, etc.). Short version of the hard limits:

• GT 555M is Fermi. Apple never shipped Fermi in a Mac. OCLP’s NVIDIA Web Driver path is aimed at real Mac NVIDIA GPUs (mostly Kepler-era stories), not this laptop’s wiring/driver combo.
• Loading GeForceWeb.kext (the accelerator) brought MMU / DMA faults (Channel exception / FAULT_PTE), white/garbled screen, etc.
• A WindowServer-free OpenCL test still failed: buffer write + read-back returned all zeros, while every OpenCL API call reported success. So host↔device DMA / GPU memory management is broken, not “just” the compositor.
• Kernel logs also showed ABI skew, e.g. unknown IOAccel context types and IOSurface “nonvolatile” skip behavior — classic mismatch between High Sierra–era accelerator (IOAcceleratorFamily2 ~378.x) and the newer userspace / IOSurface stack Ventura needs.
• Side finding: leftover Tesla Web Driver kexts in /Library/Extensions can break AuxKC linking (_VSLGestalt bind failure) and prevent GeForceWeb from loading at all. Worth cleaning if you experiment — but fixing that still did not make acceleration work on Ventura.

Bottom line for me: on Ventura 13.7.8, GT 555M can do framebuffer / native res, but true GPU acceleration is not achievable with the available Web Driver + OCLP patch set. Not a config.plist tweak left to try.

Downgrade plan: macOS High Sierra 10.13.6

I’ve stopped pursuing Ventura for daily use on this machine and I’m preparing / installing macOS High Sierra 10.13.6.

Why High Sierra:

• It is the last macOS with official NVIDIA Web Drivers for this class of GPU.
• On 10.13.6, Web Drivers are a native stack (no Ventura-era IOSurface / accelerator ABI stitching).
• Goal: keep the XPS usable day-to-day with real GPU-composited UI, which Ventura cannot deliver on GT 555M.
• Trade-off accepted: older OS, but actually usable graphics.

I’ve built a separate OpenCore 1.0.7 install EFI aimed at 10.13.6 (install-time nv_disable=1, FakeSMC/AICPM path closer to older working USB-EFI, then Web Drivers after install and drop nv_disable).

Happy to share results once High Sierra + Web Drivers are up. If anyone on the Optimus L702X thread has a clean 10.13.6 + GT 555M Web Driver checklist that still works in 2026, I’d appreciate pointers — keeping in mind my 3D unit has no iGPU.
