Use before changing or debugging clud's terminal/PTY path on macOS (POSIX PTY, raw mode, libc termios/openpty type differences from Linux, escape sequences, terminal restore). Covers what differs from Linux, how to catch macOS-only compile errors early, and when a macOS platform implementation change needs ci-full; shared business logic calling platform code stays on routine CI.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Terminal / PTY on macOS
Shared facts (data flow, the three invariants, test tiers, act rules, CI
labels) are in
[docs/architecture/terminal-pty.md](../../../docs/architecture/terminal-pty.md).
The pump, escape gate, stream scanners, signal handling and terminal
restore are the **same POSIX code as Linux**. Read
[terminal-pty-linux](../terminal-pty-linux/SKILL.md) for those. This page
lists only what differs on macOS.
## What is different on macOS
- **No local execution.** There is no local macOS machine, and `act` cannot
run macOS jobs. Any runtime behaviour can only be observed on GitHub's
hosted macOS runners.
- **libc signatures and types differ from Linux.** Both of these were
verified while #1707 carried a `libc::openpty` call; the current tree has
none.
- `libc::openpty` takes `*mut termios` and `*mut winsize` on macOS, but
`*const` on Linux. Passing `std::ptr::null_mut()` compiles on both.
- `libc::tcflag_t` is `u64` on macOS and `u32` on Linux. An `as` cast that
is a no-op on one platform trips `clippy::unnecessary_cast` on the
other. Prefer `From` / `try_from` or slice copies.

How to install
mdr add zackees/clud/terminal-pty-macos@sha256:8acc34ee363a2e08The line at the top of this page pins the label git:20261003.6479ce9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
