Third-Party Accessibility Overlay Platform for macOS
C5/10May 19, 2026
WhatA developer platform and SDK that lets third-party apps provide system-level accessibility enhancements on macOS, working around Apple's increasingly locked-down OS surface area.
SignalDevelopers are frustrated that Apple locks down macOS so tightly that third parties cannot patch accessibility shortcomings or build competing accessibility tools, and believe the ecosystem would be years ahead if developers could still extend the OS surface like they used to.
