Disk Diet is a disk cleaning utility for macOS that helps users reclaim storage space by safely identifying and removing unused files and folders. It scans for and cleans application logs, system logs, caches, trash, downloads, mail downloads, old iOS software updates, unused applications, redundant language files, and developer build artifacts from Xcode. Originally released in 2011 and continuously updated since, it has earned a MacWorld GEM award and is used by over 100,000 Mac users. The app is optimized for both Intel and Apple Silicon Macs.

1 suggestionDisk Diet is already a native Universal Binary build and has been since version 5.5 (released in 2021). The latest version 5.6.3, released in October 2025, runs natively on Apple Silicon with no performance penalties or Rosetta emulation required. If you are running an older build of Disk Diet from before 2021, simply visit tunabellysoftware.com and download the current version to get the native Apple Silicon build and access all recent improvements. Users on current builds have nothing to do — Disk Diet will continue to run natively on any future macOS release, including macOS 28.
