| Setting | Value | |---------|-------| | | Enabled | | DVMT Pre-Allocated | 64 MB or higher (96 MB preferred) | | DVMT Total Gfx Mem | MAX (256 MB or 512 MB) | | IGPU Multi-Monitor | Enabled | | Above 4G Decoding | Enabled | | Resizable BAR | Disabled (can cause issues) | | CSM | Disabled |

Budget-friendly options, though getting older. Ensure you buy a genuine RX 580 (2048SP models require vbios flashing to work).

DVMT Pre-Allocated is too low. Solution: Set to 64MB or higher. If your BIOS locks this behind a CFG Lock, you need to use framebuffer-stolenmem and framebuffer-fbmem aggressively. Try 00003001 (48MB) or 0000F001 (240MB).

Building a Hackintosh in 2026 with 12th, 13th, or 14th Generation Intel Core processors is a powerful alternative to modern Macs, but it comes with a major hurdle: . While Apple never officially supported Alder Lake+ integrated graphics, the community has developed patching methods that allow macOS to utilize these GPUs fully.

If you are using an AMD dGPU and want the UHD 770 to handle background tasks (like video encoding) without driving a display, add this to :

OpenCore Auxiliary Tools (OCAT) or Propertree to edit your config.plist . Step-by-Step: Patching UHD 770 (OpenCore)

Before applying patches, ensure your system is properly prepared:

Set to PEG (PCI Express Graphics) if using an AMD GPU. 2. CPU Spoofing (ACPI and Kernel Patches)

To build a stable system using these workarounds, ensure your hardware aligns with these compatibility standards: Compatible Options Intel Core i5-12600K, i7-13700K, i9-14900K All feature the UHD 770 igpu. Motherboard Intel Z690, Z790, B660, B760

After flashing and entering the BIOS, you must ensure the iGPU is allocated enough memory:

Your AAPL,ig-platform-id or device-id might be incorrect. Try removing device-id first or switching to a headless ID.

This happens if macOS tries to load drivers for the UHD 770. Double-check that your DeviceProperties class-code spoofing is correct, or simply add -wegnoigpu to your OpenCore boot-args.

: Some users have successfully used the UHD 770 by running macOS as a virtual machine (VM) on a Linux host (like Proxmox). In this setup, you can perform an iGPU passthrough to a Windows or Linux guest, but macOS still lacks the drivers to use it natively. Alternative Solutions
