Uni Detector
Uni Detector is a free macOS utility that scans your Applications folder and displays detailed information about each app's binary architecture. It identifies whether installed applications are compiled for Apple Silicon (arm64), Intel (32-bit or 64-bit), PowerPC, or as Universal Binaries supporting multiple architectures. It also reports other metadata including bundle ID, creation date, launch count, minimum macOS version, scriptability, category and version. Users can check all apps at once or inspect individual applications, and view statistical summaries of architecture and category distribution across their installed software. It is particularly useful for users planning transitions between Mac architectures or evaluating compatibility before hardware upgrades.
AI Recommendation
1 suggestionUni Detector version 1.3 and later is a native Apple Silicon Universal Binary, so it already runs natively on M-series Macs. If you are using an older build, update to the latest version through the Mac App Store — simply open the App Store app, search for Uni Detector, and click Update. The native build has been available since macOS 11 (Big Sur) and runs significantly faster and more efficiently than an Intel-only copy would under Rosetta. Because Uni Detector is itself a tool for inspecting binary architectures, having it run natively ensures the most accurate detection and fastest performance when scanning your applications folder.
