CheckApps 1.0

Check apps compatibility for macOS 27

CheckApps helps you find out which of your installed applications are ready for Apple Silicon. As Apple continues its transition away from Intel, many older apps built only for x86_64 will no longer run on macOS 27. CheckApps scans your Applications folder, including nested subfolders and the built-in system apps, and identifies the architecture of every app it finds, so you know exactly what's compatible and what needs an update.

The scan reads each app's Mach-O executable directly, detecting Intel-only, Apple Silicon native, and Universal binaries with precision. Results are presented at a glance with a clear compatibility overview, a visual breakdown of how much of your library is ready, and a searchable list of every app with its version and architecture. Selecting any app reveals a detailed view showing its bundle identifier, version, file size, location, and a plain-language compatibility verdict.

CheckApps does the hard work of inspecting binaries so you don't have to guess. Whether you're preparing for a macOS upgrade, auditing a Mac before handing it off, or simply curious about what's running under the hood, it gives you a complete picture of your software library in seconds. Everything is processed locally on your Mac, no data leaves your device.
