Tonality CK
Tonality CK (formerly Tonality Pro) is a professional-grade black-and-white and monochrome photo editing application for macOS. It specializes in converting color images to black and white and enhancing monochrome photographs with over 150 professional one-click presets. The app offers stackable layers, custom textures, a native 16-bit RAW processor, authentic film effects, lens blur, and advanced tools for enhancing structure and detail. It has been recognized by Apple as Editor's Choice and is designed for photographers seeking specialized monochrome editing capabilities beyond general-purpose photo editors.
AI Recommendation
1 suggestionTonality CK has not received a meaningful update since late 2016 — the latest publicly documented release is version 1.4.2 from October 2016, nearly a decade ago. There is no evidence of a native Apple Silicon build, and the developer (MacPhun Software, now part of Skylum) appears to have ceased active development of this title in favor of their other photography products. The Intel-only Tonality CK will continue to work under Rosetta 2 today, but Apple is removing Rosetta 2 in macOS 28 (late 2027), at which point this app will stop launching entirely. If you rely on Tonality CK for black-and-white editing, you should begin exploring alternatives now. Skylum's current product line (Luminar, Aurora HDR) runs natively on Apple Silicon, though they do not include Tonality's specialized monochrome workflows. For a dedicated black-and-white editor with active support, consider Silver Efex Pro (a Lightroom/Photoshop plugin from DXO Labs, which ships as a native build), or use the monochrome capabilities built into modern versions of Lightroom, Capture One, or Photoshop — all of which have native Apple Silicon support and are actively maintained.
