## Summary Stacked on #26708. Adds the macOS implementation of the shared system-proxy contract. This allows Codex-owned auth clients to use the route macOS selects for each auth URL through SystemConfiguration and CFNetwork, including PAC and WPAD results. The `respect_system_proxy` feature is disabled by default, so existing client behavior remains unchanged unless explicitly enabled. ## Implementation - Adds the macOS-only `system-configuration` dependency to `codex-client`. - Dispatches system-proxy resolution to `outbound_proxy/macos.rs` on macOS. - Reads system proxy settings from `SCDynamicStore` and resolves the target URL with `CFNetworkCopyProxiesForURL`. - Executes PAC URLs and inline PAC JavaScript through a bounded run loop with a five-second timeout. - Handles `DIRECT`, HTTP proxies, and CFNetwork HTTPS entries using HTTP CONNECT; unsupported SOCKS entries map to `UnsupportedProxyScheme`. - Builds concrete proxy URLs from host and port entries, including IPv6 host bracketing. - Maps results into the shared `SystemProxyDecision::{Direct, Proxy, Unavailable}` contract. - Hashes URL-specific cache keys so PAC decisions remain distinct without retaining raw request URLs or query strings. ## End-user behavior - Disabled/default: existing client behavior is unchanged. - Enabled with `[features.respect_system_proxy]`: - macOS auth clients honor system proxy configuration, PAC, and WPAD; - valid OS/PAC `DIRECT` decisions use a direct connection; - unavailable system resolution falls back to explicit environment proxy variables, then `DIRECT`, through the shared contract from #26707. - Unsupported proxy schemes are not silently translated into another route. - Custom CA handling remains separate from proxy selection. - Known limitation: only the first supported system/PAC candidate is used. Subsequent proxy or `DIRECT` candidates are not attempted after a connection failure. This matches the current Windows behavior and leaves room for future ordered-fallback support. ## Tests - `just test -p codex-client` — 34 tests passed. - `just clippy -p codex-client` - `just fmt` - `just bazel-lock-check`

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
