TestCard
TestCard is a Mac utility that displays a standard television test pattern (test card) on your display. It is used by video professionals, broadcasters, technicians and hobbyists for display calibration, video equipment testing, and verifying colour accuracy and signal integrity. The app generates a full-screen test pattern with standard elements such as colour bars, grey scale, resolution grids, and alignment markers.
AI Recommendation
1 suggestionWe could not find public information confirming whether TestCard has a native Apple Silicon build. The bundle ID and minimal search results suggest this may be a niche utility with limited online documentation. If you rely on TestCard for professional display testing, contact the developer directly to ask whether a native Apple Silicon version exists or is planned. This is important to confirm soon, since Apple will remove Rosetta 2 in macOS 28 (September 2028), at which point an Intel-only build will no longer launch. In the meantime, the app will continue to run under Rosetta 2 on your current Mac. As alternatives, DaVinci Resolve (free, natively supports Apple Silicon and includes colour grading and display calibration tools), or generic colour calibration apps like ColorLogic or Eizo's ColorNavigator may partially cover your needs, though they are not perfect replacements for a dedicated test card generator.
