David W. Plummer, the visionary behind the original Task Manager, is embarking on an ambitious journey to reimagine this essential tool for a broader audience. With a focus on macOS as the launchpad for his new creation, Task Manager OG (TMOG), Plummer aims to provide a robust system console tailored for users of graphical user interface-based operating systems.
Innovative Features and Design
TMOG promises to deliver a sophisticated experience that emphasizes code efficiency, comprehensive data presentation, and the performance advantages inherent to native applications. Plummer’s goal is to elevate the user experience beyond what is currently offered by macOS’s basic Activity Monitor.
During his tenure at Microsoft, Plummer developed the original Windows Task Manager in his spare time, a project that gained traction when Windows NT lead developer Dave Cutler recognized its potential and integrated it into the operating system. TMOG seeks to replicate this success, offering a powerful yet user-friendly interface that allows users to quickly assess how their operating system utilizes CPU, GPU, and other hardware resources.
- Detailed insights into processor frequency and thermal values
- Resource allocation metrics
- In-depth analysis of each logical CPU core’s activity
- Process branching visualization

Plummer’s passion for speed and code efficiency is evident in his recent project, TinyRetroPad, a minimalist clone of Windows Notepad. This commitment to performance drives his decision to utilize native APIs for TMOG, with the macOS version developed using Swift and AppKit, while the forthcoming Windows version will be a pure Win32 application optimized for the x86-64 architecture.
Availability and Future Plans
The beta version of TMOG is already accessible to macOS users, with a Windows beta anticipated shortly. Plummer has announced that the tool will be available for free, although there are plans for a potential “Pro” version that may include additional features for a fee.
TMOG exemplifies the growing demand for high-quality, power-user software that allows for detailed monitoring of a computer’s operating system. For many Windows users, Task Manager remains an indispensable tool for gaining insight into system performance.
Despite his contributions to the software landscape, Plummer’s career has not been without controversy. After leaving Microsoft in 2003, he founded SoftwareOnline, which faced legal challenges from the Washington State Attorney General over allegations of scamware products. The lawsuit concluded with Plummer’s company agreeing to pay 0,000 in civil penalties and ,000 in legal fees.
