How to Successfully Boot and Install macOS on Lenovo IdeaPad Gaming 3

Attempting to install macOS on laptops like the Lenovo IdeaPad Gaming 3 (typically equipped with an Intel Core i7-10750H and a dedicated NVIDIA GTX 1650 GPU) often fails due to complex hardware configurations and GPU compatibility limits. This guide details how to resolve installation freezes and boot errors.

1. Prerequisites

  • Hardware Specifications: Intel Core i7 10th Gen, Intel UHD Graphics 630 (active), NVIDIA GTX 1650 (must be disabled), 8GB/16GB RAM.
  • Required Kexts: Lilu, VirtualSMC, WhateverGreen, AppleALC, and RealtekRTL8111.

2. Compatibility Snapshot

  • Supported Hardware: The Intel i7 processor and UHD 630 iGPU are fully supported.
  • Unsupported Hardware: The NVIDIA GTX 1650 is NOT supported in macOS and must be disabled using boot arguments.

3. Installation Preparation

  1. BIOS settings: Disable Secure Boot, Fast Boot, Intel Platform Trust Technology (PTT), and set SATA Controller Mode to AHCI.
  2. Installer creation: Use gibMacOS to create a GUID partition style bootable installer USB.

4. EFI and config.plist Review

  1. Disable NVIDIA GPU: Add the boot argument -wegnoegpu under NVRAM boot-args. This forces WhateverGreen to disable the unsupported GTX 1650 dGPU, preventing early boot freezes and saving battery.
  2. SMBIOS configuration: Configure the SMBIOS as MacBookPro16,3 or MacBookPro16,4 for optimal Coffee/Comet Lake laptop compatibility.

5. Post-Installation

  1. USB Port Map: Perform USB port mapping using USBToolBox to ensure system sleep and wake cycles work correctly.

6. Troubleshooting

Reported Issue: Unsuccessful installation boots
  1. Stuck on PCI configuration: Add npci=0x2000 to your boot arguments if the bootloader hangs early on PCI device registration.
  2. Trackpad issues: Add VoodooI2C.kext and VoodooI2CHID.kext to restore multi-touch support for the internal trackpad.

7. Dual Boot and Advanced Configuration

  • Dual Drive setup: Install macOS on a dedicated SSD. Do not share the Windows NVMe SSD to avoid partition map corruption.

8. Verification, Maintenance and Rollback

  • Check Acceleration: Go to About This Mac and verify that Intel UHD Graphics 630 is reported with 1536MB of VRAM.
  • Rollback Plan: Always keep a copy of your working EFI on a FAT32 formatted USB drive.

9. References and Glossary

  • -wegnoegpu: A WhateverGreen boot argument that disables non-supported discrete GPUs.
