Dock icon stays visible even when “Hide Dock icon when last window closes” is enabled

Bug report:

OS version:

macOS 26.5, build 25F71

BoltAI app version:

BoltAI 2.13.3, build 72

Setapp user:

No. I’m using the standalone app installed at /Applications/BoltAI 2.app.

AI provider & model:

N/A. This is a window/Dock behavior issue and is not related to an AI provider or model.

Steps to reproduce:

1. Open BoltAI 2.

2. Go to Settings > General.

3. Enable “Hide Dock icon when last window closes”.

4. Disable “Show menu bar” because I do not want the menu bar icon either.

5. Close all BoltAI windows, including the Settings window. Do not quit the app.

6. BoltAI continues running in the background, but its Dock icon remains visible.

7. I also tried turning “Show menu bar” back on, toggling “Hide Dock icon when last window closes” off and on again, then restarting BoltAI. The Dock icon still remains visible.

Expected behavior:

After the last BoltAI window is closed, BoltAI should continue running in the background and the Dock icon should disappear.

Actual behavior:

BoltAI keeps running in the background, no BoltAI windows are open, but the Dock icon still stays visible.

Additional diagnostics:

The preference appears to be saved correctly: app.hideDockWhenNoWindows = true

System Events reports no open BoltAI windows, but NSRunningApplication still reports BoltAI’s activationPolicy as regular, so macOS keeps showing it in the Dock.

Error message:

No error message.
