Testchart Editor
Testchart Editor is a specialized tool used for creating and editing test charts for display calibration and color profiling workflows. It is part of the DisplayCAL ecosystem, a comprehensive suite for monitor profiling and color management on macOS and other platforms. The app is primarily used by photographers, designers, and color-critical professionals who need precise display calibration and ICC color profile creation. It works in conjunction with DisplayCAL's measurement and profiling capabilities to generate custom test patterns and validate display behavior across different color spaces and brightness levels.

1 suggestionTestchart Editor is part of the DisplayCAL project, an open-source color management suite. Based on available information, DisplayCAL has been transitioning toward Apple Silicon support, but the status of the Testchart Editor component specifically remains unclear from public sources. The project appears to be actively maintained on GitHub. Your best course of action is to check the official DisplayCAL GitHub repository (https://github.com/eoyilmaz/displaycal) for the latest version and Apple Silicon compatibility status. If a native Apple Silicon build is not yet available, the developers are likely working on it given the project's active maintenance. In the interim, the Intel version should continue to run under Rosetta 2 on Apple Silicon Macs. For color profiling on Apple Silicon, you may also consider ArgyllCMS as an alternative command-line tool if DisplayCAL support becomes unavailable, though it has a steeper learning curve.
