The Notifications tray button opens Notification Center when clicked. ApexDock doesn't render its own notifications UI — that's macOS's job.
Toggling visibility
Settings → Bar → Tray Icons → Notifications.
How it works
Clicking the bell asks macOS to open Notification Center the same way clicking the system clock does.
This requires Automation (System Events) permission. Grant in Settings → Permissions → Automation, or accept the prompt the first time you click the bell.
Notes
- There's a slight delay between click and reveal (a small fraction of a second). That's the round-trip to macOS, not ApexDock.
- If Control Center isn't running (rare), nothing visible happens. Relaunching it from
/System/Library/CoreServices/ControlCenter.appfixes it.
