UI Browser 3.0.0


SUMMARY: PFiddlesoft releases UI Browser 3.0.0, an update to the "ultimate assistant" for Apple's AppleScript GUI Scripting and Accessibility technologies in macOS Sierra 10.12 or later.

QUECHEE, VERMONT -- November 30, 2020 -- PFiddlesoft today announced the release of version 3.0.0 of its popular product, UI Browser, the "ultimate assistant" for GUI Scripting with AppleScript, and a developer utility for exploring Apple's Accessibility API.

UI Browser helps you to explore, manipulate, and monitor the user interface of most macOS applications running on your computer. With the push of a button, it also generates AppleScript statements to control any application using GUI Scripting, even applications that are not otherwise scriptable. No other utility provides all of the information you need in order to write scripts using GUI Scripting.

UI Browser 3 is a Universal app. It runs natively on an Apple silicon Mac under macOS Big Sur 11 as a 30-day free trial and with a Paddle registration key. It must run using Rosetta translation on an Apple silicon Mac with an existing UI Browser 2 eSellerate key.

Version 3.0.0 requires macOS Sierra 10.12 or later. In addition, it includes these new features:

You may purchase a registration key for UI Browser 3 for $55. It is a free upgrade for owners of an existing UI Browser 2 Paddle or eSellerate key. However, owners of a UI Browser 2 eSellerate key purchased on or before June 30, 2019 must purchase a Paddle key to run UI Browser on an Apple silicon Mac as a native process instead of using Rosetta translation. UI Browser 1.4.1 is no longer supported and no free upgrade path is available.

UI Browser is based on the PFiddlesoft Frameworks, including the PFAssistive and PFEventTaps Frameworks. The frameworks are written using Objective-C, and they support 64-bit architectures using reference counted memory management and ARC. Developers can license the PFiddlesoft Frameworks for distribution or use with their own products that use Apple's Accessibility and Quartz Event Taps technologies. The frameworks may be licensed free of charge for personal use or for distribution or use with a free software product. A modest license fee is required to distribute or use the frameworks with a product for which payment is requested or required. Source code is available for a separate fee. Different terms apply to large or established commercial software developers. For more information, go to
