 ### Fixed
 
+- Fixed `fd` auto-download on macOS x86_64 by pinning the last release that ships an Intel macOS binary ([#4559](https://github.com/earendil-works/pi/issues/4559)).
 - Fixed skill diagnostics to stop warning when a skill name differs from its parent directory ([#4534](https://github.com/earendil-works/pi/issues/4534)).
 - Fixed prompt template argument parsing to split unquoted multiline input on newlines ([#4553](https://github.com/earendil-works/pi/issues/4553)).
 - Fixed `--resume` session listing to cap in-flight session metadata loads and avoid OOM on large session histories ([#4583](https://github.com/earendil-works/pi/issues/4583)).
