ProcessSpy
ProcessSpy is a native macOS process monitor and system utility built as a serious upgrade to Apple's Activity Monitor.
Our verdict
Who it's for
See every macOS process in detail, from CPU to network
Who should look elsewhere
Requires macOS 14 (Sonoma) or newer, so users on older macOS versions cannot install it.
Pros
- +Hierarchical tree view with rolled-up aggregate metrics makes parent-child process relationships and XPC service links immediately visible.
- +Deep metadata inspection, including entitlements, environment variables, bundle IDs, and code-signing status, exposes process details that Activity Monitor hides entirely.
- +JavaScript-based filter engine supports complex, multi-condition logic for precise process isolation, far beyond simple name or PID search.
- +Lightweight and native (not Electron-based), so the monitor itself does not meaningfully inflate the resource numbers it is measuring.
Cons
- −Requires macOS 14 (Sonoma) or newer, so users on older macOS versions cannot install it.
- −Advanced features, including process history, environment variable inspection, and entitlements, are behind a paid license rather than available in the free tier.
- −No Windows or Linux support; it is macOS-exclusive by design.
