PFiddlesoft has released version 1.5.2 of its PFEventTaps Framework, which helps developers write assistive Mac applications for persons with disabilities using Apple’s Accessibility and Quartz Event Taps APIs on OS X.

The PFEventTaps Framework was updated to work around an Apple bug in the CoreGraphics framework that can cause a crash when running under OS X v10.10 Yosemite or older. The PFAssistive Framework was created in 2003 as the engine driving PFiddlesoft’s UI Browser application for developers and for users of Apple’s AppleScript GUI Scripting technology.

The frameworks are written using Objective-C. They support the Intel 64-bit architecture using reference counted memory management or ARC, and they support client applications written in Objective-C or Swift. Developers can license the PFiddlesoft Frameworks for distribution or for 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 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 pfiddlesoft.com/frameworks/.
