Testchart Editor
Testchart Editor is a specialized tool for creating and editing test charts used in colour calibration workflows, particularly in association with display profiling and printer characterization. It is part of the DisplayCAL ecosystem, a suite for building and applying ICC colour profiles on macOS and other platforms. The tool is primarily used by photographers, colour scientists, print technicians, and anyone working with precise colour reproduction workflows who needs to generate custom test targets or modify existing chart data for calibration purposes.

1 suggestionVery little public information is available about Testchart Editor's native Apple Silicon status. Based on the bundle ID (net.displaycal.DisplayCAL-testchart-editor), it appears to be a component or utility within the DisplayCAL colour management suite. To find out whether a native Apple Silicon build exists or is planned, contact the DisplayCAL project directly — check the project's website or repository (likely hosted on GitHub or SourceForge) and ask the maintainer explicitly about native Apple Silicon support before macOS 28 arrives in September 2028. If the project is no longer actively maintained and no native build is available, you will need to identify an alternative colour profiling workflow before Rosetta 2 is removed, as the Intel build will stop launching on that release. Other established colour management tools with confirmed native Apple Silicon support include ColorLogic ZistonePrint, i1Profiler, and BasICColor, though these are typically premium commercial products.
