Uncovering the Best fseventer Alternative for Mac and Windows
fseventer is a powerful tool designed to graphically observe filesystem changes on macOS, leveraging the same underlying API as Spotlight. It’s incredibly useful for identifying which files are altered during software installations, preference changes, or any other system activity. However, if you're seeking a different approach, cross-platform compatibility, or a specific feature set, exploring a robust fseventer alternative is essential.
