UI Browser is the ultimate assistant for Apple’s Accessibility and AppleScript GUI Scripting technologies. It helps you to explore, monitor, and control the user interface of most applications running on macOS.
Sooner or later you are going to face the problem of automating an application that either isn’t scriptable or that fails to expose some important feature to scripting. When that happens, AppleScript GUI Scripting is your only alternative and UIBrowser will be the best money you’ve ever spent.
The new 2.8 release brings support for macOS Mojave and Script Debugger 7.
