How to Increase VRAM Allocation on Apple Silicon Mac
Advanced Mac users may wish to manually increase the VRAM allocation on their Apple Silicon Mac for performance reasons when engaging in graphics intensive tasks like running LLMs locally, AI models, or any graphics heavy applications, whether for gaming or video editing. This is possible because Apple Silicon chips offer unified memory architecture, meaning the CPU and GPU share the same memory pool, and while the system will dynamically allocate memory as needed, advanced users can also manually tweak VRAM allocation from RAM on their Mac.
Important: This is genuinely only appropriate for advanced Mac users who have a compelling reason to adjust VRAM themselves, as improperly allocated VRAM may cause significant performance issues, memory problems, or even system crashes. If you’re not familiar with how memory allocation may impact performance, for better or worse, and you’re not comfortable using the command line, this one is not for you.
