TL;DR fix

The full fix is in The Fix section below. Verified on macOS Sequoia 15.x.

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

The "System Settings" app launches, but the sidebar and content area are empty, or the app hangs immediately.

Open Terminal and run:

killall -9 com.apple.systempreferences.service

Run this command to clear the user-level preferences cache:

rm -rf ~/Library/Caches/com.apple.systempreferences

Sometimes a specific pane is the problem. Try launching a specific settings pane via Terminal to bypass the main menu:

open x-apple.systempreferences:com.apple.preference.network

If this works, the issue is likely with the "General" or "Appearance" cache.

If the issue persists, try creating a New User Account in Terminal. If it works there, your main user profile has a deeper corruption.
