Hi, can anyone help me install macOS on my Dell Latitude 3420? The OpenCore program says it’s incompatible due to my GPU, but a kext for it actually exists—please help!

When I download macOS using nullmoth 1401, this error appears during the download process. what to do?

​

Hi everyone,

I'm running macOS 26 on my Lenovo Legion 5i using OpenCore, 1401, and NullMoth. I'm experiencing noticeably worse performance than on Windows 11, not just in benchmarks but also during basic everyday tasks.

The main issue: macOS feels sluggish despite my hardware. Opening System Settings for the first time can take several seconds, settings icons and sections sometimes load slowly, and opening Terminal can briefly trigger the spinning rainbow cursor. The overall UI responsiveness feels far below what I would expect from an i9-14900HX.

Audio and video stuttering have already been resolved after switching browsers and updating macOS and the drivers. However, the general UI sluggishness and low CPU benchmark scores remain.

System specifications

Component| Details

Laptop| Lenovo Legion 5i 16IRX9 Gen 9

CPU| Intel Core i9-14900HX

GPU| NVIDIA 4060 Laptop, 8GB VRAM

RAM| 32GB DDR5 5600MHz

Storage| 1TB NVMe SSD

macOS| macOS 26.7.1 (Build 25G241)

Bootloader/setup| OpenCore + 1401 / NullMoth

NVIDIA driver| NullMoth 2.6.2

CPU benchmark comparison — Geekbench 7

Results from the same laptop running Windows 11 and macOS:

Test| Windows 11 | macOS 26

Single-Core| 2,509 | 1,145

Multi-Core| 19,330 | 9,915

These are substantial differences, and they seem consistent with the sluggish experience I'm getting in macOS.

GPU benchmark comparison — Geekbench

OS | GPU | Graphics API | Score

Windows 11 | 4060 Laptop | Vulkan | 94,108

macOS 26 | 4060 Laptop| Metal | 6,830

Note: These GPU scores use different graphics APIs, so they aren't directly comparable. I'm including them as reference data, not claiming a specific percentage of GPU performance loss.

The NVIDIA driver is installed and its kexts appear to be loaded. Geekbench detects the 4060 and reports Metal 3 support.

What I've checked so far

- "machdep.cpu.brand_string" reports Intel Core i9-14900HX.

- "machdep.cpu.core_count" and "machdep.cpu.thread_count" both report 32.

- "machdep.xcpm.mode" returns "1".

- "pmset -g therm" reports "CPU_Speed_Limit = 100" and "CPU_Available_CPUs = 32".

- "CpuTopologyRebuild.kext" is enabled.

- "ProvideCurrentCpuInfo = True".

- "ctrsmt=full" is present in my boot arguments.

- "X86PlatformPlugin" appears to be active.

- An idle "top" sample showed approximately 94% CPU idle, around 20GB RAM used, 12GB unused, and no swap activity.

Any help or advice would be greatly appreciated!

Wanting to try out Sonoma or Sequoia, even without acceleration, but I can't really confirm if it can. Lotta websites saying different things.

(Information is in the CPU-Z window at the gallery, did this to not get warned by Reddit for 'not complying with Rule 4)

Got the 780M displaying on macOS Sequoia. Not daily-drivable yet since graphics acceleration isn't working, so it's still framebuffer-only for now. I'll keep updating this post as I get everything sorted.

When I saw developments like WhateverXE and XEGfx, I got curious. Yeah, I know it’s silly, but I’m curious. Do you think I should wait or give it a try?

Thanks to the legend, u/War_Obvious, I was able to refactor his Tiger Lake XPS13 repo to support the 1235U Iris Xe in my Thinkpad E14 Gen 4 i5.

What works:

GPU - Full Acceleration and Metal

Wifi - Airportitlwm kext supported

Blueooth

Webcam

Keyboard,Trackpad: Full support

What doesn't work:

Audio - Currently trying to make my own driver

GPU Artefacts - When loading preview, images are blocky with patches missing, unable to adjust brightness and apply night shift, no sleep etc. There's instructions for some of this on the repo so it's just a case of getting around to it.

iCloud - Unable to sign in and verify - Low priority for now but likely just a simple SMBIOS fix.

Will share my EFI repo once it's up!

Finally got macOS Tahoe 26.7.2 running on my Lenovo IdeaCentre Gaming 5!

Hardware:

• CPU: Intel Core i5-12400F (no iGPU)
• GPU: NVIDIA GTX 1650 SUPER 4GB
• Wi-Fi/Bluetooth: Intel AX201
• Audio: Realtek ALC623
• Monitor: MSI G2412, 165Hz

What I used:

• OpenCore 1.0.9 + 1401
• NullMoth 2.6.2 for NVIDIA acceleration
• AirportItlwm 2.4.0-alpha for native Wi-Fi
• AppleALC 1.9.8 + SimpleHDA 1.0.0 (alcid=13) for audio

Working

• NVIDIA graphics acceleration and 165Hz
• Native Wi-Fi, Bluetooth and Ethernet
• Analog audio via 3.5mm jack
• iCloud, iMessage and FaceTime
• Handoff / Universal Clipboard (iPhone → Mac)
• Windows 11 dual boot
• Apple startup chime

Known issues

• AirDrop and Mac → iPhone clipboard don't work
• Firefox graphical glitches with hardware acceleration enabled (fine when disabled)
• One duplicate audio output

Pretty happy with the result, especially considering the GTX 1650 SUPER is a Turing GPU!

Managed to get the latest tahoe running on my unsupported igpu! almost everything worked just fine.

The kext i used (https://github.com/JulioNectar/Hackintosh-XPS13Plus-IrisXe-Tahoe) was optimized for 26.7.1, which could explain the cursor stutters i had, although i'm not the only one having this issue

Not having acceleation during setup is painful but i'd say it was worth a try! could see this coming a long way

have asus tuf f15 fx507zc4
• intel i5-12500h (igpu iris xe eu80)
• nvidia 3050mobile
• wifi 6 intel ax201
tried with both nootedgreen/nullmoth(1401), getting stacked in exitbs:start, tried to fix with booter quirks, nothing. tried with ai, 0 result.. took a break, just want to know, this attempts worth it?

ps sr for my english if sounds bad, not native speaker /

Yup, as you read from the title. I managed (After hours) to get El Capitan installed on here in a "kind of stable" state.

Specs:

- CPU & GPU: Intel Core i5-7440HQ, paired with integrated HD 630 graphics. (Spoofed as a HD 530).

- Memory: 12GB of DDR4.

- WiFi Card & BT: Intel Dual-band AC 8265NGW.

Notes:

- Occasionally, it has a tendency to kernel panic after waking from sleep for a long periods of time. I still have yet to find the root cause of this.

Now U and P is working and some HX and some ultra 15th but why H don’t have any driver?

Hello, Everyone! Most of ya'll saw this post by u/Pure-Housing-7128. I tried it, it didn't work on Monterey 12.7.6 because it requires MacOs 14 and up.

This motivated me to backport the whole github repo to bigsur. so i made this github repo. this is not done, since i need to fix every bug that i come across. if anyone could help, that would be phenomenal. thank you!

Its Status: Phase 1 skeleton. The driver attaches to PCI 10EC:B723, enables the device and maps BAR2. It does not provide Wi-Fi yet.

Source: https://github.com/AA-EION/RTL8723BE-macOS-WiFi/

Repo link: https://github.com/superjhay29/RTL8723BE-Kext-Legacy-Driver

I DID IT WITHOUT ANY AMD OR NVIDIA!

Based on dssoftx/Hackintosh-X1Carbon-G11-IrisXe-Tahoe (NootedGreen stack, ported from JulioNectar's XPS 13 Plus work).

Hardware

OpenCore, SIP 0x0A13, amfi_get_out_of_my_way=1.

Working: Metal acceleration, hardware cursor, brightness slider and Fn keys, Night Shift, speakers, built-in mic, webcam, keyboard, USB, battery.

Partial: touchpad (polling, occasional "lost arbitration"), headphones (worked once, now silent), Wi-Fi (hidden SSID won't join).

Not working: HDMI.

Fixes beyond upstream

• Stolen memory reported in 4 MB units (GGC GMS 0xF0-0xFE); Apple decodes GMS x 32 MB. Patched IGMemoryManager::initSegments and FBMemMgr_Init.
• ngreen-eu=48 ngreen-l3=6 for the 48-EU part.
• Cursor showed 16-px dashes: Apple writes it through the GGTT aperture (controller+0xc98) and those writes don't reliably reach the pages the display reads. Fixed by backing the cursor range with our own WC buffer and redirecting Apple's pointer to it.
• Night Shift: GAMMA_MODE_A pre-CSC degamma bit (31) garbles display 13; masked it.
• PNLF at _SB.PC00.GFX0.PNLF (DSDT has \PNLF as an NVS field), duty rescaled to the panel PWM period.
• Audio: Tahoe removed AppleHDA, so SimpleHDA. AppleALC's CX8070 profile re-targeted to 0x14F11F87. SN6140 reports headphone pin 0x16 as a vendor-defined widget (wcaps 0x00f00000); an executeVerb hook reports it as a pin.
• Fn keys: Huawei uses EC queries + WMI; an SSDT turns _Q0A/_Q0B/_Q0D-_Q0F into VoodooPS2 key notifies.
• Touchpad: BLTP7840 is declared under PC00, not its I2C controller; an SSDT adds it under I2C0.

Open questions

1. HDMI on a Type-C port in legacy mode (ADL-P/RPL + Apple TGL framebuffer): hwDoGMBusRequest only accepts bus < 8, TC pins are 9-14, so I remap. With an HDMI connector on DDI 4 the Mac freezes at boot when a screen is attached; hot-plug after boot is never seen. Anyone done this?
2. SN6140 headphones silent although AppleHDA selects the headphone source. Any known vendor init?
3. VoodooI2C on RPL (VoodooGPIOTigerLakeLP, INTC1055): GPIO interrupt never fires, so polling.

So I was trying to setup my efi via opencore guides and it finally boot into macOS recovery. So i was excited to install and… my NVMe drive won’t show up… I was installing NVMefix.kext and NVMexpressDXE.efi and… no luck (sorry for the horrible English…)
My SSD is a KIOXIA KBG40ZNV256G.
I’m trying to install macOS sonoma on it.

Hi guys, i have a dell latitude 5400, i wated to dulaboot it with macos tahoe on the same drive, i cant add another as i dont have a spare ssd, i was researching a bit and saw that it may carry some risks as in windows efi can override and kill the mac efi or something or i need to make a separare partition on my ssd for mac efi of 100mb on exfat partition and got heavily confused, can someone help clear this up and help me please?

Has anyone run WhateverXe on an MSI Modern 14 B11MOU (i3-1115G4, device ID 9A78)?

Is there any progress on internal eDP panel support for Tiger Lake laptops?

no wifi so need to buy a usb to Ethernet to work around first and see if the wifi work, the isntaller is smooth not like MacOs 26 slow , tired see all tomorrow sleep

I can't find any information that it was solved in official opencore documentation or anything.

With same process. Tahoe did not boot
