Electron Version

29.3.1

What operating system are you using?

macOS

Operating System Version

macOS Sonoma 14.4.1 (23E224)

What arch are you using?

arm64 (including Apple Silicon)

Last Known Working Electron version

29.0.1

Expected Behavior

When using desktopCapturer.getSources({ types: ["screen"] }) on macOS Sonoma, the returned promise should immediately resolve/reject when no permissions are given.

Actual Behavior

desktopCapturer.getSources({ types: ["screen"] }) correctly prompts a system permission dialog and adds the Electron app to the permissions list if not already present. However, the promise returned by the function call does not terminate unless the user enables the permission switch in the settings page. This causes the app to deadlock if the user decides not to grant the permission, as the promise never resolves (nor rejects).

Additional Information

Running the test case from the gist on electron v29.0.1, the promise will immediately resolve and output the log from the finally branch.
On v29.1.0 and above, the promise will never resolve, unless the user checks the permission switch in the system settings.
Looking at the release notes of 29.1.0, it seems that this MR is related:
use ScreenCaptureKit exclusively on macOS 14.4 and higher
