CompareMerge2
CompareMerge2 is a macOS file and folder comparison app for reviewing differences and merging text or binary content.
What is CompareMerge2?
CompareMerge2 is a native macOS developer tool for comparing files, folders, and archives, then merging the differences when needed. It is designed for users who review source code, synchronize project folders, inspect changed documents, or reconcile versions of text and binary files. The app supports side-by-side comparison and merge workflows, including folder comparison, text diffing, and binary merge features. It also includes options that help when working with structured development files, hidden items, and ZIP archives. CompareMerge2 is published by Tien Thinh Vu and is available for Mac through the App Store, making it useful for programmers, technical users, and anyone who regularly needs to inspect file changes on macOS.

Safety overview
Status: Mostly safe
CompareMerge2 is a legitimate comparison and merge utility for macOS. It needs access to the files and folders you choose to compare, which is normal for this type of app. Because it can edit and merge content, the main practical risk is overwriting changes if you save a merge result without reviewing it carefully. Keep backups of important work before merging large folders or source files.
Recommendation: Keep CompareMerge2 if you actively use it to compare or merge files on your Mac. If you no longer need that workflow, you can remove it without affecting macOS, though any app-specific settings or saved working state may be lost.
