To make /review work on macOS without Git errors, you can configure the environment so Git has access to temporary files and cache. Step by step:

⸻

1. Create your own temporary directory

mkdir -p $HOME/tmp

2. Tell Git to use this directory

export TMPDIR=$HOME/tmp
export TEMP=$HOME/tmp
export TMP=$HOME/tmp

This redirects all temporary files for Git (and commands run via /review) to your directory.

3. Check directory permissions

chmod 700 $HOME/tmp

4. Run /review from this terminal

It’s important that the environment variables are set before running /review, for example:

/tmp/codex-review-thread # or however your command is invoked

5. (Optional) Add to .zshrc or .bashrc

So you don’t have to do it every time:

export TMPDIR=$HOME/tmp
export TEMP=$HOME/tmp
export TMP=$HOME/tmp

This fixes both issues: Git no longer tries to write to /tmp, and the Operation not permitted error disappears.

Even with the --dangerously-bypass-approvals-and-sandbox option, I still encounter this permission issue.

    instead.
