I built MacSpaceBack after noticing a gap between macOS storage warnings and the tools available to act on them. When disk space runs low, the system alerts you, but understanding what actually needs to be removed is often unclear. Many cleanup apps rely on deep folder trees, which can be powerful, but also time-consuming and overly technical. In reality, disk space is usually consumed by large files that haven’t been used in a long time—old installers, exports, archives, videos, or forgotten downloads. The core issue I was facing is how to find low hanging fruits without investing too much time and effort.
MacSpaceBack takes a different approach. Instead of giving you tools to navigate the entire file system, it focuses on two signals that matter most: file size and time since last use. By combining these, it highlights the biggest space consumers that are most likely safe to remove, without requiring deep navigation. The result is a clear, prioritized view of what’s taking space and why—so reclaiming storage is simple and deliberate.
