Move Ollama Models to an External SSD on Mac
Ollama stores its model library under the user home directory by default. Moving that library can free internal storage, but the destination must stay mounted, use a stable path and have enough capacity for current models, temporary downloads and future growth.
Plan the Ollama library migration
Enter the existing library and destination details. The migration checklist appears after you click Plan the move.
Measure the library before moving it
Confirm the current model directory size and compare it with available external capacity. Leave room for partial downloads, model updates and filesystem overhead.
Keep the destination path stable
A model runtime cannot load files from a drive that is disconnected or mounted under a different path. Use a dedicated drive name and avoid casually renaming it after configuration.
Test before deleting the original copy
Complete the migration, restart the runtime and load several models from the new location. Remove the original library only after the new path works reliably.
Frequently asked questions
Where are Ollama models stored on macOS?
Ollama documents the model directory under the user .ollama folder. Check the current official documentation because application behavior can change.
What happens if the external SSD is disconnected?
Models stored only on that drive will be unavailable. Stop active workloads before disconnecting it and reconnect the drive before starting the runtime.
Should I use a symbolic link or a configured model path?
A configured storage path is generally easier to understand and maintain when supported. A symbolic link can work, but it adds another layer to troubleshoot.
