UI Browser End of Life: UI Browser will reach its end of life and be retired on October 17, 2022. The current release of UI Browser, version 3.0.2, will not be updated. On the end-of-life retirement date, the PFiddlesoft website will be closed. Thereafter, it will no longer be possible to download or purchase UI Browser, and product support will no longer be available. UI Browser has been a labor of love for me, its sole developer for almost twenty years. Now that I am 79 years old, it is time to bring this good work to a conclusion. Bill Cheeseman, April 17, 2022.

Important Bug Notice: UI Browser does not support sending script statements to Late Night Software's Script Debugger 8. A workaround is to copy and paste the statements, instead.

UI Browser 3 is a Universal app. It runs on an Intel-based Mac, and it runs as a native process on an Apple silicon Mac during the trial period and with a Paddle registration key. It requires Rosetta translation to run on an Apple silicon Mac with an eSellerate registration key.

UI Browser 3 is a free upgrade from UI Browser 2 with this qualification: On an Apple silicon Mac, you must run UI Browser 3 under Rosetta translation in order to continue using a UI Browser 2 eSellerate key issued on or before June 30, 2019. To run UI Browser 3 natively on an Apple silicon Mac, you must use a UI Browser 2 Paddle key issued after June 30, 2019, or purchase a new Paddle key.

If you are developing a macOS application, use UI Browser to help design its Accessibility features and test their conformance to Apple's Accessibility requirements.

If you are writing AppleScript scripts to manage an existing macOS application, use UI Browser to help script the user interface using GUI Scripting even if the target application does not support AppleScript. UI Browser understands the arrangement of an application's UI elements and knows their AppleScript names and index numbers. It enables you to navigate the Accessibility hierarchy and generate useful GUI Scripting statements with a single click.

UI Browser is easy to master. Open its Target menu to choose an application, and select any of the User Interface elements in its main window. Even easier, press a hot key while holding the mouse over any of an application's UI elements on the screen, or switch to UI Browser's built-in Screen Reader and select the UI element under the mouse. UI Browser can even follow focus while you use the target application and highlight the selected element on the screen.

Open UI Browser's drawers to get and set the selected element's attributes, perform actions on the selected element, and observe notifications when the selected element changes. Another drawer lets you send keystrokes to the focused element of the target application. Use the AppleScript menu to generate GUI Scripting statements that perform the same tasks even when UI Browser is not running.

UI Browser takes full advantage of the Accessibility and GUI Scripting features built into macOS. You can write and distribute scripts that run under macOS Monterey 12 and all the way back to Mac OS X 10.3 (Panther).

UI Browser uses Apple's Hardened Runtime for increased security, and it has been notarized by Apple to assure users that it is from a trusted developer and was scanned for malicious code by Apple to ensure its security. UI Browser and the scripts that it generates may require user authorization to perform some tasks.
