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:
⸻
- Create your own temporary directory
mkdir -p $HOME/tmp
- Tell Git to use this directory
export TMPDIR=$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.
- Check directory permissions
chmod 700 $HOME/tmp
- Run /review from this terminal
It’s important that the environment variables are set before running /review, for example:
/tmp/codex-review-thread # or however your command is invoked
- (Optional) Add to .zshrc or .bashrc
So you don’t have to do it every time:
export TMPDIR=$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.
