UI Browser 2.6.3


SUMMARY: PFiddlesoft releases UI Browser 2.6.3, an update to the "ultimate assistant" for Apple's AppleScript GUI Scripting and Accessibility technologies.

QUECHEE, VERMONT -- July 17, 2017 -- PFiddlesoft today announced the release of version 2.6.3 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.

Version 2.6.3 of UI Browser incorporates PFEventTaps Framework 1.5.4 with minor bug fixes. It also works around an Apple bug in macOS Sierra 10.12 that prevented UI Browser from displaying menu extra bars and menu extras for any target application that installs them; it fixes a longstanding crashing bug when UI Browser is in Follow Focus mode and selecting a new UI element causes another element, such as a pop-up menu, to close; it changes how the target application's name is determined for display when in Follow Focus mode to comply with Apple Technical Q&A QA1544; and it fixes a bug that prevented the use of the arrow keys to navigate UI Browser's main browser view after selecting a new UI element or opening or closing a UI Browser drawer.

It also incorporates the changes made in UI Browser 2.6.0 through 2.6.3, which accommodated security improvements recently made to our in-app and online web stores managed by eSellerate, provided new instructions for purchasing a license when running UI Browser in Mac OS X 10.7 (Lion) or OS X Mountain Lion 10.8, added support for new accessibility features introduced by Apple in OS X Mavericks 10.11 and macOS Sierra 10.12, and added the following additional improvements:

New customers may purchase UI Browser for $55, with quantity discounts available. It is a free upgrade for registered owners of UI Browser 2.0.0 and newer. 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 now 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
