# Test block-clone functionality on macOS (APFS).
#
# APFS is the default filesystem on modern Macs and natively supports
# clonefile(), so no special setup is needed — just run the tests.
#
# Usage:
#   ./scripts/test_scripts/block-clone-test-mac.sh [path-to-zencore-test]
#
# If no path is given, defaults to build/macosx/<arch>/debug/zencore-test
# relative to the repository root.
