ZenBar

ZenBar is a macOS SwiftUI utility to control menu bar behavior in fullscreen for installed apps.

It manages the AppleMenuBarVisibleInFullscreen key in each app's defaults domain so you can quickly choose:

• Stock (remove override)
• Force Hide (set to false)
• Force Show (set to true)

Features

• Scans installed apps from:
  • /Applications
  • /System/Applications
  • ~/Applications
• Fast searchable app list
• Per-app menu bar mode control:
  • Stock
  • Force Hide
  • Force Show
• Batch state discovery using defaults find AppleMenuBarVisibleInFullscreen

How It Works

ZenBar runs the same defaults commands you would run in Terminal.

• Force Hide:
  • defaults write <bundle-id> AppleMenuBarVisibleInFullscreen -bool false
• Force Show:
  • defaults write <bundle-id> AppleMenuBarVisibleInFullscreen -bool true
• Stock:
  • defaults delete <bundle-id> AppleMenuBarVisibleInFullscreen

Requirements

• macOS 15+
• Xcode 16+

Run Locally

1. Clone this repo.
2. Open ZenBar.xcodeproj in Xcode.
3. Select the ZenBar scheme.

Usage

1. Launch ZenBar and let it scan installed apps.
2. Search by app name or bundle identifier.
3. Choose a mode per app:
   • Stock - remove override
   • Force Hide - hide menu bar in fullscreen
   • Force Show - show menu bar in fullscreen
4. Re-enter fullscreen in the target app (or relaunch the target app if needed).
