Troubleshooting macOS Display Flickering After Update
Experiencing screen flickering on your Apple Retina display after a macOS update? This guide provides troubleshooting steps to resolve the issue.
Software Solutions
- Adjust Refresh Rate: Go to System Settings > Displays > Advanced Display Settings. Select a suitable refresh rate (e.g., 60 Hz) to sync your GPU and display.
- Reduce Visual Effects: In System Settings > Accessibility > Display, enable "Reduce Transparency" and "Reduce Motion" to lessen the GPU load.
- Clear Display Preferences: Delete files like "com.apple.windowserver.plist" in /Library/Preferences/ via Finder. Restart your Mac to regenerate clean configurations. For more tips on optimizing your Mac, see Speed Up Your iPhone: Clear Your Cache.
- Check External Connections: Inspect cables and monitors for damage. Disconnect all peripherals, restart, and reconnect individually to identify any faulty hardware. If using an external monitor, consider the design improvements discussed in Magic Mouse Redesign: Addressing User Complaints and Embracing Modern Ergonomics.
- Update/Uninstall Apps: Ensure third-party apps, especially those interacting with display settings, are updated. Uninstall any incompatible apps causing conflicts.
- Update macOS: Check for the latest macOS updates in System Settings > General > Software Update to install bug fixes and GPU patches. Stay informed about the latest updates, such as those mentioned in January 2025 Pixel Update: Android 15 Security Patch.
- Factory Reset (Last Resort): Back up your data and perform a factory reset via System Settings > General > Transfer or Reset > Erase All Content and Settings. Restore from iCloud afterward.
