RB App Checker Lite helps users and developers to check code signatures and receipts for applications from any source. It will show certificates, requirements and entitlements, 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 Lite will also work for Xcode archives, iOS .ipa app bundles, frameworks, command-line executables, and most other bundles containing executable code.
The results will be shown as a text report, with pop-up buttons explaining details.
It does not use the codesign tool or any developer-exclusive software.
The Direct Download version (only) will show the Gatekeeper assessment via spctl.
