About DissectMac

DissectMac is a privacy-focused Mac app for finding what fills up a drive. It maps every folder to scale so large items are easy to spot, and it digs into places Finder hides, such as System Data, Xcode DerivedData, the Docker disk image, node_modules folders and local AI model caches from tools like Ollama and LM Studio.

The map and analyzer are free, while the Pro version adds clearing caches, app leftovers and developer files in a few clicks. Everything runs locally: files are not uploaded, no account is needed, and the app is notarized by Apple and built for macOS with Apple Silicon as the priority.

Pro is sold as a lifetime license rather than a subscription, with a 15-day money-back guarantee, and the key is sent by email. DissectMac suits anyone who sees a vague System Data bar in Settings and wants an explanation, including developers with many cloned projects.
