What is System Toolkit Pro?
System Toolkit Pro is a native macOS utility that combines live system monitoring with storage cleanup tools. It helps users watch CPU, memory, network, disk, temperature, fan, and battery information while also finding files that can be removed to recover space. Common uses include checking performance from the menu bar, reviewing current system load, locating large or old files, finding duplicate files, and uninstalling apps together with related leftover data. The app also offers a compact info panel and dashboard views for quick status checks during everyday Mac use.

Safety overview
Status: Mostly safe
System Toolkit Pro is a legitimate Mac utility for system monitoring and cleanup. Some cleanup features may request Full Disk Access so the app can scan files across your Mac, which is a normal permission for this kind of tool. Because it can help remove files, duplicates, and app leftovers, take a moment to review proposed deletions before confirming them, especially if you keep project files or large media libraries.
Recommendation: Keep System Toolkit Pro if you use its monitoring widgets or cleanup tools regularly. If you no longer use it, removing it is usually fine, but you may want to do a final review of any saved scans or cleanup lists before uninstalling.
