Uhd 770 Hackintosh May 2026

Fix: In BIOS, set Internal Graphics to Enabled (not Auto). Also set DVMT Pre-Allocated to 128MB. Gigabyte firmware has poor ACPI handoffs for iGPU.

Add these properties to PciRoot(0x0)/Pci(0x2,0x0): uhd 770 hackintosh

In your config.plist, go to Misc -> Security: | Setting | Value | |---------|-------| | CSM

| Setting | Value | |---------|-------| | CSM | Disabled | | Above 4G Decoding | Enabled | | Resizable BAR | Disabled (causes issues on Hackintosh) | | DVMT Pre-Allocated | 64MB or higher | | Primary Graphics Adapter | IGFX (if no dGPU) or PEG (if dGPU) | | VT-d | Disabled (or use dart=0) | | CFG Lock | Disabled |

For E-cores (if you keep them enabled): Use CpuTopologyRebuild.kext and -ctrsmt boot argument, but stability varies.

Streaming services (Apple TV+, Netflix, Disney+) via Safari or native apps will fail. You’ll see black screens or error messages because the DRM handshake (FairPlay) requires a supported GPU.
