Advanced process monitor for Mac
About ProcessSpy
What is ProcessSpy?
ProcessSpy is an advanced process monitor for macOS that goes far beyond what Apple's built-in Activity Monitor offers. It provides deep, real-time insight into every running process on your Mac, showing details like full command-line paths, version numbers, environment variables, and digital signatures. Designed for developers and power users, ProcessSpy turns vague process names into clear, actionable information.
Who it's for
- Developers who need to distinguish between multiple instances of the same application (like Java apps running different JDK versions) by seeing full command-line arguments, paths, and version details.
- System administrators and power users who want to track historical performance data, monitor resource spikes over time, and export findings to CSV for deeper analysis.
- Troubleshooters and security-conscious users who need to inspect an app's digital signature, entitlements, bundle ID, and startup entry type to verify legitimacy and understand system impact.
Key features
Advanced Tree View with Aggregate Totals
ProcessSpy's tree view automatically groups child processes and links related XPC services by their responsible PID. It rolls up aggregate totals for CPU, Memory, and Threads, so you can instantly see the true system footprint of an app and all its helpers — without losing the ability to search or filter in real time.
Inspector Pane for Deep Process Details
The Inspector Pane reveals exactly how an application interacts with your system. Check if an app runs natively, verify its digital signature, track precise memory usage, and monitor disk read/write speeds. It's an essential tool for developers and power users who need to stop guessing what's happening under the hood.
Historical Performance Logging
ProcessSpy logs CPU, Memory, and Thread data over time, mapping out aggregate values and active states on visual timelines. You can pinpoint exactly when a resource spike occurred, view peak and average usage, and export everything to CSV for reporting or further analysis.
