Ollama on macOS is distributed as a desktop application that also provides the ollama command-line client. The app manages the local server while the CLI lets terminal workflows use the same models and API.
Current requirements are macOS Sonoma or newer, with Apple M series Macs receiving CPU and GPU support and Intel Macs using CPU-only support. Model storage can grow quickly, so check free disk space before pulling large models.
The preferred install path is to mount the DMG, drag Ollama.app into Applications, start it, and allow the app to create the CLI link when prompted.
