OmniDiskSweeper for Mac is a software that enables macOS users to clean up their hard drives. It is a free application developed by The Omni Group and allows users to scan their hard drives to create an organized list of all their content. The application is safe to use, with a clean user interface that does not include advertisements or malware. The developers are committed to maintaining the privacy of the users, and if there are changes to the security standards, the users will be notified.


The user interface of OmniDiskSweeper has multiple panels that expand the categories of libraries after scanning the hard drive. Users can click on each category to see the content of each folder. The titles with an arrow to the right expand to allow users to browse additional items. The user interface is designed in the style of the Macintosh HD menu, and items are listed in descending order in each panel. Large files and folders are at the top of the lists, while content with zero bytes is usually found at the bottom of the record.

Users can select the hard drive they want to evaluate from the Drive List that appears when they launch the software. The window shows both external and internal hard disks that are connected, with the amount of free, used, and total space written next to each drive. The software lets users delete files directly in the user interface by clicking on the Delete button. However, this feature is not always practical since images are not displayed when an item is highlighted, and users may not realize what they are deleting.

While the native macOS disk utility manager does give users storage information, it has its limitations. It cannot open certain categories, such as 'System' and 'Other.' However, OmniDiskSweeper allows users to scan these areas to view the content. Although the software gives users a comprehensive view of their system, the user interface makes deleting risky. To reduce the risk of deleting important files, users can search for the record in the Finder app, which allows them to see a preview or launch the content to let them securely delete unwanted files, documents, applications, folders, etc.

It used to be a paid application, but it is now free. Users have unlimited access to the platform when they download and install the software. Since Omni Disk Sweeper app is lightweight, users do not have to compromise their storage space to optimize their hard disk.
