Docker and OrbStack
Free disk space used by Docker Desktop, OrbStack and Colima. Reclaim removes build cache, unused images, stopped containers and volumes with Docker's own commands.
What you need
The docker command and a running engine: OrbStack, Docker Desktop, Colima or another. Reclaim finds the command in the usual places, even when it is opened from Finder. Open Containers in the sidebar; if the engine is not running, start it and click Refresh.
What is listed
| Item | What it is | Removed with | Level |
|---|---|---|---|
| Build cache | Layers kept to speed up builds, not used by any image now. | docker builder prune --all | Safe |
| Dangling image | An untagged image left behind when a newer build took its tag. | docker image rm | Safe |
| Unused image | A tagged image no container uses. Pulled or built again when needed. | docker image rm | Rebuild |
| Stopped container | A container that is not running. Changes made inside it are lost. | docker container rm | Rebuild |
| Unused volume | A volume no container uses. These often hold databases. | docker volume rm | Personal |
Images, containers and volumes that are in use are never listed. Select a row to read what it is and what happens after removing it.
How removal works
Docker items share the Delete bar and the history with everything else. If Docker refuses an item, the summary shows Docker's reason and the item stays in the list.
About the sizes
Sizes come from docker system df. For an image, Reclaim shows the space only that image uses, which is what removing it frees; layers shared with other images stay. Totals can differ slightly from Docker's own summary because Docker rounds each size it reports.
Disk Map and duplicates
See where your Mac's disk space went with a size-sorted Disk Map, find large files, and remove duplicate files with APFS clones handled correctly.
System and the helper
Delete root-owned system caches, logs, sudo leftovers and local Time Machine snapshots on Mac with Reclaim's optional, locked-down helper.
