Context

Generals Base (non-expansion game) is fully functional on Linux with SDL3 + DXVK + OpenAL stack.

Goal

Port Generals Base to macOS (ARM64 Apple Silicon primary target) using the same unified codebase:

• SDL3 for windowing/input
• DXVK + MoltenVK for DirectX 8 to Vulkan to Metal graphics
• OpenAL for audio
• 64-bit native

Acceptance Criteria

• Generals Base builds and runs on macOS ARM64 with presets
• Game reaches main menu and loads skirmish maps
• Graphics render via DXVK + MoltenVK correctly
• Audio plays (music, SFX, voice)
• Same determinism as Linux build (no logic regressions)
• CMake preset macos-vulkan or separate preset configured

Notes

Reference: GeneralsXZH (Zero Hour expansion) is already working on macOS. Backport should be straightforward for shared platform/backend code.
