- Human work and limitations
- The project status is experimental. The distinction between the primary Vulkan renderer (via MoltenVK) and the experimental Metal renderer is noted in the source. FSR 3.1 is listed as a core feature, while FSR 4.1.1 is a newly integrated, optional feature for Metal.

What was done
An experimental macOS port of Bloodborne that runs natively on Apple Silicon using a custom CPU recompiler and renderer. It requires a user-provided game dump (v1.09) and features a dedicated launcher, in-game settings, and support for AMD FSR 3.1 and optional Metal-based FSR 4.1.1.
Bloodborne-mac is an experimental project that enables the PS4 game Bloodborne to run natively on Apple Silicon. The project utilizes a custom CPU recompiler (bloodborne-recomp) and a renderer that supports Vulkan via MoltenVK, with an experimental native Metal renderer also available. The project diverges from the original bbport Linux port and shadPS4, though it remains built upon their foundational work. Users must provide their own game dump with the 1.09 update to function. The application includes a dedicated launcher for managing mods, patches, and graphics settings, alongside an in-game settings menu. While the project is considered playable, it is explicitly labeled as experimental with known risks of crashes and graphical corruption. Performance testing has been limited; the README reports that on an Apple M3 Pro at 1080p using FSR 3.1, the game achieves approximately 60 FPS in the Hunter's Dream and 44 FPS in the clinic. Recent updates, including version 0.8.3, have integrated optional FSR 4.1.1 support for Metal and resolved issues with the launcher's mod and patch lists.
