OmniDiskSweeper
OmniDiskSweeper is a free macOS utility that displays files on a drive from largest to smallest. This ordering helps users locate large unwanted files, open them, or remove them. Moving items to the Trash is the default action; holding the Option key enables direct deletion instead. The utility can scan external drives. Omni says the version compatible with macOS 26 makes the entire app accessible with VoiceOver, and the product page lists older downloads for macOS 10.4 through 10.13. The freeware download requires no form or personal information. Omni says it does not share data gathered from its apps or websites with social media or advertising services. Support is available by email and phone Monday through Friday, 10am–5pm Pacific Time. The company notes that OmniDiskSweeper is updated less frequently than its other titles, although it still receives updates. The Omni Group is employee-owned and based in Seattle, Washington.
