What is System Toolkit?
System Toolkit is a native macOS utility that helps users watch system activity and clear space used by temporary data. It combines live monitoring for CPU load, memory usage, network activity, open connections, temperatures, voltages, currents, and fan speeds with a menu bar interface for quick access. The app also includes cleanup tools for cached and temporary files across user, app, developer, and browser categories, making it useful for people who want both system visibility and routine maintenance in one place. Battery details for supported Macs and battery levels for compatible Bluetooth devices are also available. This makes System Toolkit a practical choice for users who want to keep an eye on Mac performance, storage use, and hardware status during everyday work.

Safety overview
Status: Mostly safe
System Toolkit is a legitimate Mac utility for monitoring hardware status and cleaning temporary data. Access to system information, disks, and connected device details is consistent with its purpose. Because cleanup features can remove caches and other temporary files, you may need to sign back into some apps or rebuild certain app data afterward. Use the cleaner selectively and review what will be removed before confirming.
Recommendation: Keep System Toolkit if you use its menu bar monitoring, hardware sensors, or cleanup tools. If you no longer use it, removing it is usually fine, but expect to lose its saved settings and any convenience features it provides for system monitoring and cleanup.
