The original code had NO activation policy override. macOS was showing
the Helper window in Ableton's Space by default. Adding Accessory policy
caused macOS to treat it differently and put it in a separate Space.
Going back to the original main.cpp that was working before the close-button fix.
fix: set NSApplicationActivationPolicyAccessory at launch to prevent separate app appearance
The helper was appearing as a separate app in Dock/Cmd+Tab because
the activation policy was never being set. The showAsFloatingPanel()
only handled window level, not the application-level policy.
Now sets policy=1 (Accessory) as the FIRST thing in initialise(),
before any windows are created. This means:
- No Dock icon
- No Cmd+Tab entry
- No focus steal when helper launches
- GUI window floats over Ableton as a panel
Fix: Helper/main.cpp use flat includes (Source/Shared in include dirs)
