Download PFAssistive Framework 3.7.1 and PFEventTaps Framework 1.5.3. Each download includes a version suitable for embedding in an application package and a version suitable for installation in the standard shared frameworks folder. Both frameworks support Mac OS X 10.7 (Lion) or later. Visit Requirements for details.

Download our Assistive Application Programming Guide for macOS, an almost 50-page PDF document explaining how to use both of the PFiddlesoft Frameworks to write assistive applications, with code examples. Also download the PFAssistive Framework Reference and the PFEventTaps Framework Reference for detailed documentation of all of the frameworks' classes, protocols, properties and methods.

Download the SimpleScreenReader 1.4.0 source code for sample code showing how to use the PFAssistive Framework.

Download the PFAssistive Testbench 1.0.1 source code for additional sample code showing how to use the PFAssistive Framework. PFAssistive Testbench also shows how to grant access to the computer in OS X Mavericks 10.9 or later in order to take full advantage of the new Mavericks Accessibility security features in your own assistive applications. PFAssistive Testbench does the same things as our free Accessibility Testbench utility except that it uses our PFAssistive Framework instead of directly calling an Accessibility API function.

Download the Event Taps Testbench 1.3.7 source code for our free Event Taps Testbench developer utility for sample code showing how to use the PFEventTaps Framework.
