TMOG monitors system performance on Windows, macOS and Linux

Dave Plummer, a former Microsoft developer who created the original Windows Task Manager in the mid-1990s, has released a cross-platform system monitor called TMOG. The free software runs on Windows 11, macOS, and Linux, tracking hardware performance and resource-heavy programs. Three decades after designing the magic tool used by millions of PC users to stop frozen software, lagging web pages, spinning fans, or draining batteries, the veteran developer is back with a much more ambitious application. Microsoft had previously entrusted its former employee with the source code of his original Task Manager, but he did not reuse a single line of it, choosing instead to write the new utility out of a love for clean code and a desire to help.

Task Manager OG Monitors CPU and RAM Across Three Operating Systems

The software, whose name stands for Task Manager Original, uses two American slang letters that designate “the original.” Upon opening, TMOG presents an overview screen displaying real-time activity and state metrics for the central processing unit, random-access memory, graphics processing unit, local drives, and network usage.

The interface lists active programs by resource consumption while displaying processor temperature and power draw in watts when hardware sensors permit. According to the creator’s design standards, the utility avoids estimating missing metrics, leaving blank spaces on performance curves rather than displaying generated values. The application is written specifically for each system in specific languages, keeping it lightweight and performant while sending no data externally except to check for update availability, though its source code remains closed.

Free Edition and Paid Pro Version Offer Different Diagnostic Tools

The standard version of TMOG is available for free download directly from the developer’s website and handles core system monitoring tasks, startup applications, and user accounts. A paid Pro tier costs approximately forty dollars without a subscription and introduces advanced electrical consumption metrics alongside a flight recorder function. This black-box feature logs background activity so users can review system performance anomalies that occurred while they were away from the computer.

Platform compatibility varies by operating system, as Windows 10 is unsupported. On macOS computers, the software requires manual installation from the official website because App Store regulations prohibit third-party applications from terminating other running programs.
