Sharpener Pro 3
Sharpener Pro 3 is an image sharpening plugin for macOS, designed to enhance photo and graphic clarity through output sharpening filters. It was developed for use with image editing applications and digital photography workflows, targeting photographers, designers, and retouchers who need fine control over sharpening for print and screen output. The app is no longer actively maintained by its developer.
AI Recommendation
1 suggestionSharpener Pro 3 has been discontinued by its developer and is no longer supported. Although the roaringapps.com database indicates a universal binary build was available at some point, the discontinuation means no further updates are forthcoming. The app will continue to run under Rosetta 2 today, but when Apple removes Rosetta 2 in macOS 28 (September 2028), Sharpener Pro 3 will stop working entirely. If you currently rely on this tool, begin exploring alternatives now: modern photo editing suites like Adobe Lightroom, Capture One, Affinity Photo, or ON1 Photo RAW all include native sharpening controls that run natively on Apple Silicon. For standalone sharpening workflows, look at focused plugins from active vendors such as Topaz Sharpen AI, which offers machine-learning-based sharpening and runs natively on M-series Macs.
