NotchBar

A tiny WoW AddOn for macOS “notched” MacBooks that aligns UIParent to WorldFrame to eliminate notch safe-area offsets and prevent UI elements from drifting after reload.

This AddOn does not change the 3D render viewport or macOS safe-area handling. It only adjusts the WoW UI layer anchoring and positions the top-center widget container.

---

Features

• ✅ Forces UIParent to match WorldFrame size to avoid notch safe-area offsets
• ✅ Reapplies alignment automatically if another addon changes it
• ✅ Moves UIWidgetTopCenterContainerFrame to UIParent TOP with a configurable offset (default 0, -30)
• ✅ Account-wide SavedVariables

Installation

1. Close World of Warcraft.
2. Download and unpack
3. drag or copy to '/World of Warcraft/classic_era/Interface' or '/World of Warcraft/anniversary/Interface'
4. Start WoW.
5. In the AddOns menu, enable NotchBar.

Usage

No slash commands. Install and it applies automatically.

How it works

The AddOn:

• Re-anchors UIParent to WorldFrame so UI coordinates match full-screen rendering
• Reapplies the anchor periodically and on key events to avoid other addons reverting it
• Repositions UIWidgetTopCenterContainerFrame to UIParent TOP with 0, -30

---

Limitations

• This AddOn cannot:
  • change the game’s 3D render size or macOS fullscreen safe-area behavior
  • “detect the notch” directly (WoW AddOns don’t have access to macOS safe-area insets)
• Another addon may still fight the anchoring; the periodic reapply should keep it aligned.

Files

NotchBar.toc

Contains metadata and loads NotchBar.lua.

NotchBar.lua

Main implementation:

• Aligns UIParent to WorldFrame
• Repositions UIWidgetTopCenterContainerFrame
• Stores settings in NotchBarDB
• Updates on:
  • PLAYER_LOGIN
  • UI_SCALE_CHANGED
  • DISPLAY_SIZE_CHANGED

Troubleshooting

The bar doesn’t show up

• Make sure the folder is exactly: Interface/AddOns/NotchBar/
• Make sure file names are exactly: NotchBar.toc and NotchBar.lua
• Check the AddOns menu and enable it
• Enable “Load out of date AddOns” if needed

The bar is too tall or too short

• Use manual mode: /notchbar 74 (try values between 60–100)
• Or tweak auto:
  • /notchbar ratio 0.040
  • /notchbar clamp 60 100

I only want it on the internal MacBook display

• Not implemented by default (WoW doesn’t provide a reliable way to identify which display you’re on from the AddOn API). You can toggle manually with /notchbar off.
