During December 2025, this developer added Apple M5 Metal GPU support to the modular/modular repository, focusing on GPU programming and system architecture using the Metal API and Mojo. The work involved implementing M5 configuration in mojo.info, creating MLIR target configuration for the new GPU, and extending GPUInfo to include M5 specifications. By following the established M4 pattern, the implementation ensured consistency across Apple Silicon GPUs and reduced manual configuration errors. This update standardized device metadata and prepared the codebase for future benchmarking and deployment on M5-equipped devices, accelerating product readiness and supporting streamlined integration of new Apple hardware.
