1. Basic Troubleshooting for macOS Problems
Before diving into advanced methods, start with some quick and easy steps. Most macOS issues are caused by simple factors like outdated caches, too many apps running at once, or insufficient storage space.
Restart Your Mac
A simple restart can do wonders for your Mac. It clears temporary files, stops background processes, and refreshes the system, often fixing minor glitches and slowdowns.
Force Quit Unresponsive Apps
If an app freezes or becomes unresponsive, force-quit it to free up system resources. You can open the Force Quit Applications window by pressing Command + Option + Escape.
Alternatively, try QuitAll, a handy app available on Setapp that allows you to quit all active apps with a single click.
Check Available Storage
A full hard drive can cause your Mac to slow down, so check your storage usage and make sure there’s enough free space. Go to Apple Menu > System Settings > General > Storage to check your available space. If needed, use tools like CleanMyMac to clear junk files and free up space.
2. Update macOS and Apps Regularly
Software updates are crucial for fixing bugs and improving performance. Regularly check for updates to ensure your system is running smoothly.
Update macOS:
- Go to System Settings > General > Software Update.
- Install the latest macOS version available.
Update Apps:
Don’t forget to update your apps. Setapp apps automatically update, but you should manually update other apps to avoid compatibility issues and bugs.
3. Use Safe Mode to Isolate Problems
Safe mode is a useful troubleshooting tool that can help you determine whether your macOS problems are caused by third-party apps or system extensions.
How to Boot in Safe Mode:
- Apple Silicon Macs: Shut down your Mac, then press and hold the power button until you see the startup options screen. Press Shift and then click Continue in Safe Mode.
- Intel Macs: Shut down your Mac, then immediately press and hold the Shift key while turning it back on.
If your Mac works fine in safe mode, the issue is likely due to a third-party app. In that case, try uninstalling recently added apps.
4. Create a New User Account
Corrupted user data can cause various problems. To test this, create a new user account and see if the problem persists.
Steps to Create a New User Account:
- Go to System Settings > Users & Groups.
- Add a new user and log in to that account.
- Check if the issue persists. If the new account works fine, the problem might be in your old account’s data or preferences.
5. Use Recovery Mode for Deeper Issues
If basic fixes don’t resolve the issue, use macOS Recovery Mode. This tool can help repair disk errors, reinstall macOS, or restore from a Time Machine backup.
How to Enter Recovery Mode:
- Apple Silicon Macs: Shut down your Mac, then press and hold the power button until the startup options appear. Select Options > Continue.
- Intel Macs: Restart your Mac and hold Command + R immediately after it starts to enter recovery mode.
Run Disk Utility First Aid:
Once in recovery mode, open Disk Utility and run First Aid to check and repair your disk.
Reinstall macOS:
If necessary, you can reinstall macOS without deleting your files. Choose Reinstall macOS from the recovery menu, and follow the on-screen instructions.
6. Scan for Malware
Although macOS is relatively secure, malware can still sneak in. If you notice unexpected performance issues or apps crashing, scanning for malware is a good idea.
How to Scan for Malware:
Use CleanMyMac, which comes with a built-in malware scanner. It will check your system for any malicious software and help you remove it.
7. Reset NVRAM or PRAM
NVRAM (Non-Volatile Random-Access Memory) stores certain system settings. If there are issues with sound, display, or Wi-Fi, resetting the NVRAM can often help.
Steps to Reset NVRAM/PRAM:
- Shut down your Mac.
- Turn it on and immediately press and hold Option + Command + P + R for about 20 seconds.
- Release the keys and let your Mac restart.

The System Management Controller (SMC) controls power functions, like battery and thermal management. Resetting it can resolve power-related issues like overheating or charging problems.
Steps to Reset SMC:
- Shut down your Mac.
- Press and hold Shift + Control + Option (on the left side of your keyboard) and the power button for 10 seconds.
- Release all the keys and turn your Mac back on.
9. Reinstall macOS Using a Clean Install
If you’re still facing issues after trying the above methods, a clean install of macOS may be necessary. This will erase everything on your Mac and give it a fresh start.
Important: Backup all important data before performing a clean install using a tool like Get Backup Pro.

If the issue is hardware-related (e.g., a faulty hard drive or RAM), you can use Apple Diagnostics to check for issues.
How to Run Apple Diagnostics:
- Apple Silicon Macs: Shut down your Mac, then press and hold the power button until the startup options appear. Press Command + D to run diagnostics.
- Intel Macs: Restart your Mac and immediately hold the D key to start the diagnostics.
