Unsupported systems use browser capture and do not request cursor-helper Accessibility access. Tests cover OS support, helper resolution, and cursor-access conditions. ChangesmacOS capture compatibility
Estimated code review effort: 3 (Moderate) | ~15 minutes Merge Risk: ⚪ Minimal · up to On macOS 12, recording now uses the existing browser-capture path without an unnecessary Accessibility prompt, while newer macOS versions retain native capture; no actionable merge-blocking risk remains after normal checks and review.

- Around line 2092-2094: Move the isNativeMacCaptureOsSupported check in the
start-native-mac-recording handler so it runs before resolving or looking up the
native helper, returning the existing unsupported-os response on macOS 12. Add a
handler-level test covering macOS 12 that verifies helper lookup is not invoked.
In `@electron/recording/nativeMacCaptureSupport.ts`:
- Around line 7-8: Update isNativeMacCaptureOsSupported to validate that the
complete macOS version string consists only of numeric dot-separated components
before parsing it. Reject malformed values such as “13.invalid” and “13beta”,
while preserving support for valid versions with a major number of at least 13.

unsupported-platform, missing-helper, and an available result that includes the
resolved helperPath. Verify each result’s status and relevant fields, and
confirm the helper lookup is skipped for unsupported platforms while invoked for

Summary
Root cause
The app supports macOS 12, but
is-native-mac-capture-availabletreated an executable helper as available on every macOS release. The helper itself is compiled for macOS 13 and exits on Monterey. The countdown independently requested Accessibility for its cursor helper before capture selection, so Monterey users were repeatedly sent through a permission flow that could never make the native recorder compatible.This keeps the documented application support range intact: Monterey uses the browser recorder, while Ventura and later retain native ScreenCaptureKit recording and editable-cursor capture.

Screenshots / video
No visual change. On macOS 12 the Record action now proceeds to the existing countdown/browser-capture path instead of repeatedly asking for Accessibility and then launching an incompatible helper.
