What is the best mac cleaner software for disk cleanup?

In my own words, dupeGuru is a specialized and best Mac cleaner that does one thing very well: it finds duplicate files on your computer. Unlike many "Mac cleaner" apps that try to do everything (cache cleaning, log removal, app uninstallation, duplicate finding), dupeGuru focuses exclusively on identifying redundant files—whether they're exact copies or just similar.

If your definition of a best Mac cleaner is a tool that finds and removes redundant, space-wasting duplicate files with surgical precision—then yes, dupeGuru is an excellent choice. One user reported finding over 17,000 duplicate files totaling nearly 16 GB of wasted space after a single scan.

However, if you're looking for a best Mac cleaner that also handles system logs, cache files, language packs, and iOS backups—dupeGuru will not do those things. It is not a system cleaner. It is a duplicate file finder.
