Meta AI Mac app screen sharing fails silently on macOS 13.6

Meta AI's Mac app fails to share individual windows on macOS 13.6.1 (Ventura), returning a NULL from CGWindowListCreateImage and aborting with 'No shareable content found', according to a user report on the Meta AI forum. The issue affects Electron-based editors like VS Code and Cursor, with a suspected ScreenCaptureKit version mismatch between Ventura (1.0) and Sonoma (2.0). A workaround using 'Share Entire Screen' works but exposes private content, and the user seeks confirmation from Sonoma users to test the version-gate theory.

Meta AI Mac app screen sharing fails silently on macOS 13.6 Here's what I've ruled out so far: Environment - MacBook Pro M2, macOS 13.6.1 Ventura - SIP enabled, no third-party kernel extensions - Screen Recording permission granted to com.meta.aimac in System Settings → Privacy & Security - Accessibility permission also granted tried both with/without What the logs actually show log stream --predicate 'subsystem == "com.meta.aimac"' --level debug yields this when I click Share Window: 2024-12-19 14:22:11.342 MetaAI 12487 : ScreenCapture Requesting capture permission for window 0x7f8b... 2024-12-19 14:22:11.344 MetaAI 12487 : ScreenCapture CGWindowListCreateImage returned NULL for window 0x7f8b 2024-12-19 14:22:11.345 MetaAI 12487 : ScreenCapture Falling back to full-screen capture 2024-12-19 14:22:11.347 MetaAI 14:22:11.347 MetaAI 12487 : ScreenCapture SCShareableContent.current.excludingDesktopWindows: false 2024-12-19 14:22:11.348 MetaAI 12487 : ScreenCapture No shareable content found, aborting The CGWindowListCreateImage returning NULL is the smoking gun. That window ID 0x7f8b belongs to my VS Code instance — confirmed via CGWindowListCopyWindowInfo kCGWindowListOptionOnScreenOnly, kCGNullWindowID . The app sees the window but can't snapshot it. Things I've tried that didn't work 1. Restarting the Mac twice 2. Revoking/re-granting Screen Recording permission via tccutil reset ScreenCapture com.meta.aimac 3. Running Meta AI from Terminal with --enable-logging=verbose — no additional output 4. Disabling "Displays have separate Spaces" in Mission Control some ScreenCaptureKit apps choke on this 5. Testing with a non-Electron window Terminal.app — same NULL return Workaround that kind of works If I choose "Share Entire Screen" instead of a specific window, the overlay appears and the model can read my screen. But that defeats the privacy model — I don't want the LLM seeing my password manager or private Slack DMs. The per-window path is explicitly advertised in their launch blog post, so this feels like a regression, not a missing feature. Suspected root cause The SCShareableContent.current.excludingDesktopWindows: false line suggests they're filtering out desktop-level windows, but VS Code on Ventura registers as a regular app window layer 0, not the desktop layer . Something in their window-filtering logic is misclassifying Electron/Chromium windows on macOS 13. The fallback to full-screen capture then fails because excludingDesktopWindows: false excludes everything. Ask Has anyone gotten per-window sharing working on Ventura 13.x ? Specifically with Electron-based editors VS Code, Cursor /en/tags/cursor/ , Zed ? I'm wondering if this is a ScreenCaptureKit version mismatch — the app bundles its own ScreenCaptureKit.framework stub, but Ventura's system version is 1.0 while Sonoma ships 2.0. If they compiled against the Sonoma SDK but didn't weak-link properly, the SCShareableContent query could return empty on older macOS. If you're on Sonoma 14.x and it works, that would confirm the version-gate theory. Also happy to test a TestFlight build if the Meta team monitors this forum. Next Llama 3. → /en/threads/6858/
