Ollama runs on Windows 10 22H2 or newer (Home or Pro), macOS Sonoma (version 14) or newer, and Linux, and a dedicated GPU is optional, according to Ollama’s official Windows, macOS and hardware support documentation.
As of November 10, 2026, Macs with Apple M-series chips get CPU and GPU support through Metal, while Intel (x86) Macs run on the CPU only. NVIDIA cards need compute capability 5.0 or higher and driver 550 or newer, or 570 or newer for compute capability 5.0 through 6.2; the Windows page lists NVIDIA driver 551.61 or newer. AMD Radeon acceleration needs a ROCm v7 driver, and Vulkan is enabled by default as an extra GPU option on Windows and Linux.
On Windows, the install needs at least 4GB of disk space and no Administrator rights. Models need additional space and can be tens to hundreds of GB. Ollama’s documentation does not publish a minimum RAM figure, so the 8 GB minimums quoted on other sites are third-party estimates.
