Notifications aren’t showing

Specter posts a small notification when a sync completes or needs your attention, but whether those appear is controlled by macOS, not by Specter. If you are not seeing them, the permission is almost certainly switched off.

Open System Settings → Notifications, scroll to find Specter (or GhostSyncBar) in the list of apps, and make sure notifications are allowed. From there you can also choose the alert style — banners or alerts — and whether they show on the lock screen. macOS only asks for this permission once, usually on first launch, so if you dismissed that prompt the toggle will simply be off until you turn it on here.

One thing worth checking alongside it: Do Not Disturb or a Focus mode will silence notifications from every app, including Specter, even when the per-app permission is on. If you have a Focus active, that may be the real cause. Once notifications are allowed and no Focus is suppressing them, Specter’s sync messages will come through normally.
