MoltenVK
An open-source compatibility layer that maps Vulkan API calls to Apple's Metal graphics framework, enabling Vulkan applications to run on macOS and iOS.
Timeline (last 90 days)
Some users shared temporary workarounds, including rolling back the system update, running an older version of macOS in a virtual machine, or converting OpenGL calls to Metal via third-party compatibility layers (such as MoltenVK).
MoltenVK is an open-source compatibility layer that translates and maps the Vulkan API onto Apple's Metal, part of the Vulkan portability implementations in the Khronos ecosystem; it does not translate OpenGL directly into Metal, but rather lets applications and engines originally targeting Vulkan run on macOS and iOS.
For legacy projects still using OpenGL, a common approach is to first convert OpenGL calls to Vulkan via solutions such as Zink and then land on Metal through MoltenVK, forming a multi-stage translation chain; this chain introduces extra CPU overhead and potential compatibility deviations, and debugging difficulty rises markedly, so it is better suited as a transitional measure than a long-term architecture.
