FileWatcher
FileWatcher is a macOS utility from Bryan Christianson that monitors file system activity and shows file and process changes as they happen.
What is FileWatcher?
FileWatcher is a macOS utility for watching file system activity in real time. It helps users see when files and folders are created, modified, renamed, or deleted, and it also reports related process start and termination events. The app presents activity in both a detailed log and a tree view, which makes it useful for troubleshooting, system observation, and understanding how apps interact with files. Advanced users, developers, and support-minded Mac users can use it to inspect live changes across the file system during testing or diagnostics. FileWatcher is published by Bryan Christianson and is distributed as a native Mac utility through the WhatRoute website.

Safety overview
Status: Mostly safe
FileWatcher is a legitimate monitoring utility, but it works by observing file system events and may request administrator access for its helper so it can reach private system locations and process information. That level of access is consistent with its purpose, but it also means the app can expose sensitive file activity while you use it. Install it only if you want this kind of diagnostic visibility, and avoid leaving it running longer than needed on shared or privacy-sensitive Macs.
Recommendation: Keep FileWatcher if you use it for troubleshooting, development, or monitoring file activity on your Mac. If you do not actively use those features, you can remove it without affecting macOS itself, though you will lose its live file-event and process-monitoring tools.
