Cleanup My System
Cleanup My System is a macOS cleanup and optimization utility from Systweak for removing junk files, managing storage, and improving system housekeeping.
What is Cleanup My System?
Cleanup My System is a native Mac utility from Systweak designed to help users clean unnecessary files, review storage use, and manage common maintenance tasks from one app. It is aimed at people who want a simpler way to free disk space and tidy their Mac without digging through folders manually. The app focuses on tasks such as scanning for junk files, identifying large or old items, clearing privacy traces, and helping remove apps with related leftovers. It also includes tools for reviewing startup-related items and looking for duplicate or redundant files that take up storage. For everyday Mac use, it fits best as a utilities app for routine storage cleanup and basic system organization rather than as a replacement for macOS itself.

Safety overview
Status: Mostly safe
Cleanup My System is a legitimate Mac cleanup utility, and the file access it requests is consistent with scanning storage, finding duplicates, removing junk, and uninstalling apps. Because cleanup tools can delete caches, browser data, login traces, or app leftovers, use its cleaning options carefully and review what is selected before confirming removal. Privacy and cleanup modules may affect saved website sessions, temporary files, or app convenience data. It is generally fine to use for routine maintenance, but it is best to avoid one-click deletion of anything you do not recognize.
Recommendation: Keep Cleanup My System if you actively use it to free space, remove junk, or manage app leftovers on your Mac. If you do not use cleanup utilities or prefer macOS built-in storage tools, you can remove it without affecting macOS itself, though you may lose its saved scans, preferences, and convenience features.
