1. Mac Freezes When Opening System Settings? You’re Not Alone 🧊
If your Mac freezes when opening System Settings (formerly System Preferences), it’s not just a bug. Many users—especially since Ventura and Sonoma—report long delays, spinning wheels, or complete freezes when trying to access macOS settings.
It’s frustrating… but you can fix it quickly with the right strategy.
2. Why System Settings Cause Freezes on macOS
Unlike the old Preferences app, the new System Settings is built on SwiftUI and loads many components dynamically. It accesses:
- All active system services (Wi-Fi, Bluetooth, iCloud, etc.)
- Background apps requesting permissions
- Login items and startup processes
- Hardware states (battery, display, keyboard, etc.)
If your Mac is already busy in the background, opening System Settings adds a layer that can freeze the system temporarily.
3. Use AppHalt to Prevent the Freeze 🛠️
With AppHalt, you can pause all heavy apps that might interfere with your Mac’s responsiveness. If your Mac freezes when opening System Settings, it’s often due to apps running background services (Dropbox, antivirus, Slack, Teams…).
Pausing them with AppHalt frees up memory and CPU—making System Settings open instantly.
4. Additional Fixes You Can Try
- Restart your Mac (then open System Settings first)
- Clear caches with apps like Onyx or CleanMyMac
- Turn off login items you don’t need
- Keep macOS and all apps fully updated
