How to Install macOS Sonoma on Intel Core i3-12100F with NVIDIA GT 730 GPU

How to Install and Patch macOS Sonoma on Legacy Kepler Graphics Systems

Upgrading a Hackintosh with an Intel Core i3-12100F and an NVIDIA GT 730 graphics card to macOS Sonoma is possible but requires applying legacy graphics root patches, since support for NVIDIA Kepler GPUs was dropped after macOS Monterey.

1. Prerequisites

• Hardware Specs: Intel Core i3-12100F CPU (requires CPU ID spoofing as Alder Lake is not natively supported), NVIDIA GT 730 (Kepler edition), 8GB/16GB RAM.
• Required Tools: OpenCore Legacy Patcher, ProperTree.

2. Compatibility Snapshot

• NVIDIA Kepler (GT 730): Only Kepler variants of the GT 730 (GK208 chipset) can be patched. Fermi variants (GF108) are completely unsupported in macOS Sonoma.

3. Installation Preparation

1. Clean install: It is highly recommended to perform a clean install when upgrading legacy graphics configurations to Sonoma.

4. EFI and config.plist Review

1. CPU ID Spoofing: Since Alder Lake CPUs are not natively supported, you must spoof your CPU ID in config.plist to match a Comet Lake CPU (e.g. 0x0A0655).
2. Disable SIP: You must partially disable System Integrity Protection (SIP) to apply root patches. Set csr-active-config to 03080000 under NVRAM.
3. SecureBootModel: Set SecureBootModel to Disabled.

5. Post-Installation

1. Apply Root Patches: Install OCLP on the system, launch it, select Post-Install Root Patches, and apply the Kepler graphics patches to restore Metal acceleration.

6. Troubleshooting

Reported Issue: Unresponsive or slow UI

1. No graphics acceleration: If the screen flashes or animations are slow, confirm that OCLP has successfully applied the Kepler root patches and that SIP is disabled.

7. Dual Boot and Advanced Configuration

• Dual booting Windows and macOS is recommended on separate SSDs. Kepler drivers are natively supported in Windows 10/11.

8. Verification, Maintenance and Rollback

• Rollback: Keep your working Monterey EFI as a backup in case Sonoma performance is not sufficient.

9. References and Glossary

• Kepler: The architecture name for NVIDIA\'s 600 and 700 series GPUs.
