RB App Checker Lite

By Rainer Brockerhoff

Open the Mac App Store to buy and download apps.


RB App Checker Lite helps users and developers to check code signatures and receipts for applications from any source. Did you get that application from Apple, from the App Store or from an authorized developer? Easy to tell.

It will show certificates, requirements and entitlements, embedded provisioning profiles, auxiliary executables and frameworks, cross-check all this information for consistency, and check that the application’s resources have not been altered after signing.

Check if your application is properly signed before submitting it to the App Store or publishing it elsewhere, or if the application you downloaded has been tampered with.

For your convenience, RB App Checker Lite also publishes a Service (right-click on any application in the Finder) and has a fast-select menu for all running applications.

RB App Checker will also work for Xcode archives, .ipa bundles, frameworks, command-line executables, pkg files created by Xcode, and most other bundles containing executable code. It does not use the codesign tool or any developer-exclusive software.

What's New in Version 1.1.5

- Now also shows some details for unsigned applications/bundles.
- Better support for more types of signed packages, also for Safari extensions and XAR archives.
- Many small fixes and internal improvements, as traditional.
