# How do I clean the pnpm store and Bun cache on a Mac?

Both keep a shared store of packages so installs are fast:

- **pnpm**: `pnpm store prune` removes packages no project references any more.
- **Bun**: `bun pm cache rm` clears Bun's global cache.

The next install re-downloads what's needed, so the only cost is a slower first install. npm, Yarn and pip are covered in [cleaning npm, yarn and pip caches](https://storagestudio.us/faq/mac-storage-basics/how-do-i-clean-npm-yarn-and-pip-caches), and per-project folders in [cleaning up node_modules](https://storagestudio.us/faq/mac-storage-basics/how-do-i-clean-up-node-modules-folders).
