# 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.
