Codex app on macOS fails automatically during context compaction
Hi OpenAI Codex team,
I’m using the latest Codex app on macOS. I encountered a recurring issue where the app automatically fails when it tries to compact/compress the conversation context.
Issue
When a Codex thread becomes long and the app starts context compaction automatically, the compaction process fails. After that, the thread cannot continue normally, and I need to restart or open a new thread.
Expected behavior
The Codex app should successfully compact the context and continue the thread, or provide a clear recoverable error message.
Actual behavior
Context compaction starts automatically but fails. The thread becomes interrupted/stuck and cannot continue as expected.
Steps to reproduce
- Open the latest Codex app on macOS.
- Start a local coding thread in a project.
- Continue the conversation until the context becomes long enough for automatic context compaction.
- Wait for Codex to compact/compress the context.
- The compaction process fails automatically.
Environment
- App: Codex app for macOS
- Codex bundled version: codex-cli 0.138.0-alpha.7
- macOS version: macOS 26.5.1, build 25F80
- Mac model / chip: Mac mini Macmini9,1, Apple M1, 16 GB memory, arm64
- Plan: [Plus / Pro / Business / Enterprise]
- Project type: Objective-C / Cocoa macOS app
- Approximate time of failure: 2026-06-10, Asia/Shanghai timezone
Additional note
Running /Applications/Codex.app/Contents/Resources/codex --version also printed:WARNING: proceeding, even though we could not create PATH aliases: Operation not permitted (os error 1)
I can provide logs if needed. Please investigate the automatic context compaction failure in the latest macOS Codex app.
