.github/workflows/unit-test.yml (1)

21-21: Timely migration to macOS 15 Intel before macOS 13 deprecation. The macOS 13 image is fully unsupported by December 8th, 2025, making this update necessary. The macos-15-intel label runs on macOS 15 and will be available from now until August 2027, providing long-term support for x86_64 workflows.

The comment accurately reflects the intent to pin the runner to the latest Intel x86_64 image. The change is well-timed to avoid workflow failures after the deprecation deadline.

However, please verify compatibility with the updated toolchain. The macOS 15 runner includes Xcode 16 by default (compared to Xcode 15.4 on macOS 13), and Java 8 has been removed from the Intel-based image. Whilst the workflow specifies Java 25 (which should be available), please confirm that FFmpeg 7.0.2 and the Gradle build process execute without issues on the new runner before merging.
