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
- BIOS settings: Disable Secure Boot, Fast Boot, Intel Platform Trust Technology (PTT), and set SATA Controller Mode to AHCI.
- Installer creation: Use gibMacOS to create a GUID partition style bootable installer USB.
4. EFI and config.plist Review
- Disable NVIDIA GPU: Add the boot argument
-wegnoegpuunder NVRAM boot-args. This forces WhateverGreen to disable the unsupported GTX 1650 dGPU, preventing early boot freezes and saving battery. - SMBIOS configuration: Configure the SMBIOS as
MacBookPro16,3orMacBookPro16,4for optimal Coffee/Comet Lake laptop compatibility.
5. Post-Installation
- 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
- Stuck on PCI configuration: Add
npci=0x2000to your boot arguments if the bootloader hangs early on PCI device registration. - Trackpad issues: Add
VoodooI2C.kextandVoodooI2CHID.kextto 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.
