Appshots hotkey registers but never fires on macOS 26.5

What version of the Codex App are you using?

Codex App: 26.519.31651 (CFBundleVersion 3017)
Computer Use helper: com.openai.sky.CUAService, version 1.0 build 799
Computer Use client: com.openai.sky.CUAService.cli, version 1.0 build 799

What platform is your computer?

macOS 26.5 (25F71), Apple Silicon / arm64

What issue are you seeing?

The Appshots hotkey appears to register successfully, but pressing the configured hotkey does not trigger Appshots.

This seems different from #23992. In #23992, the log contains Appshot hotkey pressed and the failure happens later during capture. In this case, Appshot hotkey pressed / Dispatching appshot hotkey never appears after pressing the hotkey.

Expected behavior

Pressing the configured Appshots hotkey should trigger Appshots and attach an appshot to the current Codex thread.

Actual behavior

Nothing is attached. The Codex UI only reacts as if modifier keys are being held, e.g. the “New chat” button changes/flickers to “Quick chat”, but Appshots does not start.

Reproduction steps

1. Open Codex App.
2. Open Settings > Appshots.
3. Set Appshots hotkey to DoubleShift.
4. Restart Codex.
5. Press both Shift keys simultaneously.
6. Observe that Appshots does not trigger.
7. Repeat with DoubleCommand.
8. Observe that Appshots still does not trigger.

Codex log evidence

Codex logs show that the hotkey is registered:

Registering appshot hotkey hotkey=DoubleShift
Registered appshot hotkey hotkey=DoubleShift
Registering appshot hotkey hotkey=DoubleCommand
Registered appshot hotkey hotkey=DoubleCommand
Registering appshot hotkey hotkey=DoubleShift
Registered appshot hotkey hotkey=DoubleShift

However, after pressing the configured hotkey, the log never contains:

Appshot hotkey pressed
Dispatching appshot hotkey

Additional diagnostic result

Running the bundled monitor directly:

/Applications/Codex.app/Contents/Resources/native/bare-modifier-monitor --key DoubleShift --immediate

prints:

ready

but pressing both Shift keys does not produce any further output.

Earlier checks with DoubleCommand also did not detect the hotkey.

Permissions and settings already tried

• Updated macOS.
• Restarted Codex after changing settings.
• Tried DoubleCommand.
• Tried DoubleShift.
• Checked Screen Recording / Screen & System Audio Recording permissions.
• Checked Accessibility permissions.
• Tried toggling bare-modifier-monitor related permissions on and off during troubleshooting.
• Tried Input Monitoring during troubleshooting.

The public Codex/Appshots documentation and release notes do not appear to mention bare-modifier-monitor or Input Monitoring as user-facing setup steps, so this may be either a hotkey monitor bug or a documentation/setup gap.

Privacy note

Local usernames, full local file paths, and full logs are intentionally omitted from this public issue. I can provide additional logs through a private/support channel if needed.
