# Siriously: recovering macOS Writing Tools entry points

> Siriously investigates how macOS 27 changed access to Writing Tools and restores its popover through a Services client. The author used Objective-C runtime introspection and behavioral tracing to identify private WritingToolsUI classes, then passes selected text to the popover and writes accepted results back through Accessibility APIs. The findings concern one macOS build.
