macOS Sonoma 14 brings useful updates, but it also introduces a range of problems that can interrupt daily use. Many people report issues like failed installs, Wi-Fi drops, apps crashing, or faster battery drain. Most of these problems can be fixed with simple steps such as restarting in Safe Mode, checking storage, updating apps, or adjusting system settings.
Troubleshooting doesn’t always require advanced knowledge. For example, if Wi-Fi stops working, removing and re-adding the network often restores the connection. If apps crash, updating them or reinstalling usually solves the problem. Even performance slowdowns often come from background processes or low storage, both of which can be managed without outside help.
By knowing the most common Sonoma 14 issues and the fixes that work, anyone can keep their Mac stable and reliable. This guide focuses on the practical steps that solve problems quickly, without unnecessary complexity.

Common macOS 14 Problems and How to Fix Them
| Problem | Resolution |
|---|---|
| Mac runs slow after update | Restart your Mac to clear memory, disable unnecessary startup items in System Settings > General > Login Items, and check Activity Monitor for resource-heavy apps. |
| Wi-Fi not connecting properly | Forget the network in System Settings > Wi-Fi, reconnect with your password, or reset network settings with sudo ifconfig en0 down && sudo ifconfig en0 up. Restart your router if issues persist. |
| Bluetooth issues (can’t pair or random disconnects) | Turn Bluetooth off/on in Control Center, delete the com.apple.Bluetooth.plist file from Library > Preferences, then restart and try pairing again. |
| Apps crashing frequently | Update the app via the App Store, reinstall if needed, and ensure macOS is up to date. Check System Settings > Privacy & Security > Full Disk Access if the app requires it. |
| Battery drains faster than expected | Open System Settings > Battery > Battery Usage to see which apps consume the most power. Enable Low Power Mode, dim brightness, and quit background-heavy apps. |
| External display not working | Verify the cable/adapter, use Apple-certified accessories, and go to System Settings > Displays > Detect Displays. If using multiple monitors, arrange them correctly in Display Settings. |
| Mac won’t wake from sleep | Check System Settings > Lock Screen > Turn display off when inactive and adjust wake settings. Try resetting SMC/NVRAM (Intel Macs) or restarting (Apple Silicon Macs). |
| Storage “System Data” too large | Open About This Mac > Storage Settings, clear caches/logs, empty the trash, and move large files to iCloud or external storage. Run Disk Utility > First Aid if needed. |
| iCloud not syncing files | Sign out and back into iCloud in System Settings > Apple ID, ensure iCloud Drive is enabled, and confirm enough iCloud storage space. Toggle Optimize Mac Storage if files aren’t downloading. |
| macOS update won’t install | Make sure you have at least 20GB free space. Restart in Safe Mode, then retry the update from System Settings > General > Software Update. If stuck, create a bootable installer via USB. |
