Codex Desktop terminal panel does not render on macOS 26.5.1 (M1 Max, arm64)

Summary

The terminal panel does not render in Codex Desktop on macOS 26.5.1. The main UI loads normally, but the terminal panel never appears when selected.

Environment

• macOS 26.5.1 (25F80)
• Apple M1 Max
• Codex Desktop 26.609.41114
• arm64 build (confirmed via binary inspection)

Steps to reproduce

1. Launch Codex Desktop
2. Open or create a workspace
3. Click the Terminal button/panel control

Expected behavior

A terminal panel opens within the workspace and is available for interactive command execution.

Actual behavior

No terminal panel is displayed. The application remains responsive, but the terminal never renders or initializes.

Troubleshooting performed

• Full uninstall and reinstall of Codex Desktop
• Removed all Application Support, caches, logs, preferences, helper services, and browser integration files
• Confirmed clean state before reinstall
• Verified arm64 binary via:

file "/Volumes/Codex Installer/Codex.app/Contents/MacOS/Codex"

• Reset macOS permissions
• Tested GPU-related launch flags (no improvement)

Additional observations

• Codex CLI works normally
• Codex Web works normally
• Issue is reproducible after complete clean install
• Appears isolated to Desktop UI terminal panel initialization
