+1 Verified on macOS 15 / Apple Silicon: - Source tarball signature and checksums. - Binary wheel (cp311, macosx arm64): sha512 and GPG signature verified; full pyarrow test suite passes (7514 passed; the Flight TLS and parquet - Binary wheel (cp311, macosx arm64): sha512 and GPG signature verified; full pyarrow test suite passes (7514 passed; the Flight TLS and tests that need ARROW_TEST_DATA / PARQUET_TEST_DATA also pass once those are provided). - Source build with TEST_PYTHON=1 (Flight/Gandiva disabled): builds fine and the core Python suite passes from source (7404 passed). - GH-50326 specifically: to_pylist() on nested types improves as expected over 25.0.0 (list<string> 3.4x, struct 10x, map 7.8x on 500k-row arrays), results exactly match the per-Scalar conversion across nested/sliced/chunked cases, and Spark's 4.2 switches to the native path with this version — outputs match its fallback implementation exactly.
