How to Fix Menu Bar Icons Disappearing in macOS Tahoe 26.2

Symptom: After using an external display or switching resolutions on macOS Tahoe, some menu bar icons (Control Center, Clock, or 3rd party apps) become invisible or truncated.

TL;DR fix

Start with Fix 1: Restart System UI Server. If the issue persists after that, try Fix 2: Reset Menu Bar Layout. Full Terminal commands and step-by-step instructions are in each section below.

Why this happens

Tahoe's new dynamic spacing for the notch can cause the SystemUIServer to miscalculate the available width for menu extras, leading to them being pushed off-canvas.

Recommended Troubleshooting Tool

Before proceeding with manual fixes, we recommend using CleanMyMac X. Quickly identify high CPU apps and optimize system memory with one click.

Fix 1: Restart System UI Server

Open Terminal.
Run the following command to force-refresh the menu bar:

killall SystemUIServer

Fix 2: Reset Menu Bar Layout

In Terminal, clear the layout cache:

defaults delete com.apple.menubar; killall ControlCenter

Recommended Tool: Bartender

To manage a crowded menu bar effectively:

- Get Bartender to hide, search, and organize your menu bar icons, ensuring they never get cut off by the notch again.
