Install Codex CLI

If you already use Codex on the Mac, this page is closer to a verification checklist than an installation guide. CodexPocketMac depends on the Mac-side Codex environment, so the codex command must be visible.

Commands to check

Run these in Terminal:

which codex
codex app-server --help

The expected results are:

• which codex prints a path
• codex app-server --help does not fail

Even when codex was installed with Homebrew, which codex may print a symlink under bin, such as /opt/homebrew/bin/codex or /usr/local/bin/codex. To confirm where it came from, inspect that path too:

CODEX_PATH="$(which codex)"
ls -l "$CODEX_PATH"

If the ls -l target, or the which codex result itself, points into /opt/homebrew/Caskroom/... or /usr/local/Caskroom/..., it is installed as a Homebrew cask.

If it does not work

• if which codex is empty, revisit the Codex CLI installation or PATH
• if it works in Terminal but the Mac app does not detect it, restart the Mac app
• you can also inspect the Codex CLI row in Details

What this enables

• starting Bridge
• fetching the Thread list for each Project
• using Composer and Fork from the iPhone

If Codex CLI is missing, the iPhone may reach the connection stage, but it will not get as far as doing real work.
