ColorSync Utility vs DisplayCAL

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.

DisplayCAL is a free display calibration and profiling solution built on ArgyllCMS, available for Linux, macOS, and Windows. With a supported measurement instrument, it measures displays and creates calibrations and ICC profiles, including for multi-display setups. Users can verify profiles and display devices, measure screen uniformity, and create video 3D LUTs with optional CIECAM02 gamut mapping. Colorimeter corrections can be imported from vendor software or created from measurements when a spectrometer is available. A test chart editor makes patch charts and accepts pasted data from CGATS, tab-delimited CSV, and spreadsheet applications. Documented pattern generators include madVR and DaVinci Resolve 10.1 or later; Chromecast support is optional. DisplayCAL requires ArgyllCMS 1.0 or newer and a supported measurement instrument. The software is licensed under GNU GPL version 3 or later and comes without warranty.
