When attempting to run a model using Ollama installed via Homebrew on macOS, the process fails with a 500 Internal Server Error indicating that the llama-server binary cannot be found.

It seems the Homebrew packaging formula might be missing a build step or failing to place the llama-server binary in the expected directory. As a user, I expect Ollama to work out-of-the-box without needing to manually compile llama-server via CMake.

Environment: OS: macOS (Apple Silicon / darwin-arm64) Ollama Version: 0.30.7 Installation Method: Homebrew (brew install ollama) Relevant log output
