Dave Plummer, who authored the original Windows Task Manager over three decades ago, has launched a new software application called Task Manager OG. This utility allows users across Windows 11, Arm, macOS, and Linux to monitor system performance and track active processes.
Why it matters
The software serves as a modern reimplementation of a foundational desktop tool, designed to help users identify specific processes that degrade system performance. It brings a familiar diagnostic interface to non-Windows environments for the first time.
The application is built using native code tailored for each platform: C++/Win32 for Windows, Swift and AppKit for macOS, and C++/QT6 for Linux. It supports performance monitoring and process tracking via its Summary and System info views.

The details
Task Manager OG operates by querying native OS process APIs (application programming interfaces — sets of protocols for building software) to monitor CPU and memory load. By leveraging C++ and Swift, the developer avoids the performance overhead typically associated with cross-platform frameworks, ensuring the utility provides low-latency visibility into resource-intensive tasks.

The Tech Race
This release follows the long-standing precedent of the original Windows Task Manager, which has served as the default system monitor for decades. It marks a departure from that platform-locked legacy by offering a native-code equivalent for Linux and macOS environments.
Users can access the tool immediately on Windows 11, Windows 11 on Arm, macOS, and Linux systems. While the base version is free, the Pro edition is available for $39.95 for those requiring advanced administrative functionality.
The takeaway
Task Manager OG demonstrates how legacy system utilities can be modernized through native platform code to support contemporary hardware architectures. Users should monitor the developer's release notes for future updates to the free versus Pro tier feature parity.
