What Is macOS Sequoia?

macOS Sequoia introduced several productivity and window-management features, including iPhone Mirroring — which lets users control their iPhone directly from their Mac — window tiling improvements, and an updated Passwords app extracted from the Keychain system. On the Safari and AI side, Sequoia added writing tools and summaries through Apple Intelligence on supported Apple Silicon Macs. The release also updated system frameworks, including refinements to ScreenCaptureKit, the API that all screen recording applications use to capture display content.

Screen recording behavior in macOS Sequoia follows the same permission model introduced in Catalina: apps must request screen capture access in System Settings > Privacy & Security > Screen Recording, and macOS displays a status bar indicator while any capture is active. Sequoia added more granular privacy controls over which windows and content can be recorded by specific apps, continuing Apple's trend of tightening screen access permissions introduced in Sonoma. Developers distributing screen recorders for Sequoia must ensure their apps are built against current ScreenCaptureKit APIs to avoid deprecation issues.

Limelight requires macOS 14 (Sonoma) or later, which means it runs on macOS Sequoia (15.x) as well. The app is a native macOS binary that uses ScreenCaptureKit for capture and runs fully offline — no content is uploaded during recording. Features like automatic click zoom, cursor spotlight, on-screen keystrokes, freehand annotations, and 9:16 vertical export function the same on Sequoia as on Sonoma. Users upgrading from Sonoma to Sequoia do not need to reconfigure Limelight, though they should verify screen recording permission remains granted in the updated Privacy & Security settings after the OS upgrade.
