Performance Issues and Slowdown
Many users notice their Mac running slower after installing macOS Sonoma 14.7.6. This is common after major updates as the system reindexes files.
To fix performance problems:
- Wait 24-48 hours for initial indexing to complete
- Restart your Mac to clear temporary files
- Check Activity Monitor to identify resource-heavy apps
If your Mac still feels sluggish, try restarting in Safe Mode to see if the problem persists. If performance improves in Safe Mode, a third-party app may be causing issues.
Battery drain is another common complaint. Check Battery settings to see which apps use the most power. Turn off background app refresh for non-essential apps and reduce screen brightness to extend battery life.
For serious performance issues, resetting the SMC (System Management Controller) often helps. The process varies between Mac models, so check Apple’s support site for specific instructions.
App Compatibility and Crashes
Some apps may crash or behave strangely after updating to macOS Sonoma 14.7.6. The first step is to check for app updates, as developers often release compatibility fixes shortly after macOS updates.
For crashing apps, try these solutions:

- On Intel Macs: Restart and hold the Shift key during startup
- On Apple Silicon: Shut down, press and hold the power button, select your startup disk, then hold Shift while clicking “Continue in Safe Mode”
If your Mac works normally in Safe Mode, the problem likely comes from a third-party app or login item. Check for incompatible apps and update or remove them.
macOS Recovery provides tools to fix more serious issues:
- Restart your Mac while holding Command + R
- Use Disk Utility to repair your startup disk
- Try First Aid on your disk to fix file system errors
Recovery mode is especially useful when macOS Sonoma won’t boot normally.
Reinstalling macOS Sonoma and Backing Up Data
Before reinstalling, back up your important data using Time Machine or an external drive. This protects your files if something goes wrong.
- Connect an external drive
- Open Time Machine preferences
- Select your drive and start the backup
For a clean install of macOS Sonoma:
- Boot into Recovery Mode (Command + R during startup)
- Select “Reinstall macOS”
- Choose your startup disk
- Follow the onscreen instructions
A clean install can fix persistent issues like app crashes and slow performance. After reinstalling, restore your apps and files from your backup.
If updates get stuck, try installing from Safe Mode as this bypasses software conflicts that might block the installation process.
Tip: Write down your Apple ID and important passwords before reinstalling, as you’ll need them during setup.
