Disk Diet is the original disk cleaning app for macOS, first released in 2011 and continuously refined ever since. Now with full support for macOS 26 Tahoe, it safely frees up gigabytes of wasted space by removing unnecessary files in just a few clicks. Highlights include: • Quick scanning that targets application logs, system logs, and caches • Removal of outdated downloads, mail attachments, and old iOS software updates • Cleanup of unused apps and leftover language translations • Automatic detection of unnecessary—and often very large—Xcode developer folders Awarded a MacWorld GEM and trusted by thousands worldwide, Disk Diet remains an essential utility for anyone needing extra space. It’s designed for speed, simplicity, and peace of mind. Friendly support is always available, with prompt responses to any questions or concerns that may come up.
