ArgyllCMS vs ColorSync Utility

ArgyllCMS is a free, open-source ICC-compatible color management system for creating profiles and calibrating devices. Its command-line tools support scanners, cameras, film recorders, displays, and RGB, CMY and CMYK printers. It can create device-link profiles with options such as video calibration standards and 3D LUTs, and work with spectral samples, selectable illuminants and observer types, and paper fluorescent-whitener compensation. Color conversion tools handle 8-bit raster data and fully accurate 16-bit conversion. Documentation lists direct support for measurement instruments from JETI, Klein, X-Rite and Calibrite, DataColor and other manufacturers; some chart results can be converted into Argyll CGATS format. ArgyllCMS runs on Windows, macOS and Linux, but does not include a graphical interface. DisplayCAL, The Little Argyll GUI and CoCa are listed as front ends that use it. The package is licensed under AGPLv3; commercial licensing is available for code copyrighted by Graeme Gill through ArgyllPRO. On Linux, native display calibration and profiling under Wayland are not currently supported; the maker recommends X11 for color-managed displays.

ColorSync Utility is Apple software for managing ICC color profiles on macOS. It is free and includes a free plan, with no listed paid tier or subscription. The documented function is profile management, so it addresses handling ICC profiles rather than calibration procedures. The available platform is macOS only. The listed capabilities do not include display calibration, printer profiling, camera profiling, or HDR calibration. That makes its scope specific: Mac users can use it for ICC profile work, but the provided facts do not describe tools for calibrating a display, printer, camera, or HDR setup. Anyone choosing ColorSync Utility should match that profile-management focus to the task.
