Mac Sai is a macOS utility for cleaning junk files, uninstalling apps, checking for malware, and reviewing disk usage in one interface.
What is Mac Sai?
Mac Sai is a native macOS utility focused on system cleanup, app removal, malware checks, and storage analysis. It helps users reclaim disk space, review large or duplicate files, manage certain maintenance tasks, and remove leftover files that basic app deletion can miss. The app also includes tools for browser privacy cleanup, login item and launch agent management, and a visual disk map for finding space-heavy folders. Mac Sai is built for people who want an all-in-one maintenance tool on Mac, including users who prefer open-source software and a straightforward desktop interface. It is published by Iliya Mirzaei and is designed for modern versions of macOS.

Safety overview
Status: Use with caution
Mac Sai is a legitimate macOS maintenance app with code signing and Apple notarization, and its cleanup, privacy, and malware-scanning features match its purpose. Some functions can remove data, clear browser traces, change login items, run maintenance tasks, or thin universal binaries, so results should be reviewed before cleaning. Features such as privacy cleanup, mail attachment scanning, and deeper system inspection may request broad disk access that is typical for this kind of utility. The bundle ID com.macclean.app also reflects the product's earlier naming, so if you are checking items in Finder or security tools, confirm they belong to the same Mac Sai installation.
Recommendation: Keep Mac Sai if you actively use it for Mac maintenance, storage cleanup, or app removal. If you installed it only to test it and do not use these tools, removing it is reasonable. Before running broad cleanup or optimization actions, review the items selected for deletion and avoid advanced options unless you understand their effect on installed apps and local data.
