Advanced Techniques to Make Your Mac Run Faster

If you’re comfortable with more technical solutions, these advanced methods can significantly enhance the performance of your Mac, including models like MacBook Pro and MacBook Air.

Method 1: Resetting SMC and PRAM/NVRAM

Resetting the System Management Controller (SMC) and Parameter RAM (PRAM)/Non-Volatile RAM (NVRAM) can resolve various performance issues. Note: For Macs with M1 chips and newer models, SMC and PRAM/NVRAM resets are not applicable as these processes are managed differently in Apple Silicon.

  1. Resetting SMC on MacBook with Non-Removable Battery:
    1. Shut down your MacBook.
    2. Press and hold Shift + Control + Option on the left side of the keyboard, then press the power button at the same time. Hold these keys for 10 seconds.reset SMC
    3. Release all keys, then press the power button to turn on your Mac.
  2. Resetting PRAM/NVRAM:
    1. Shut down your Mac.
    2. Turn on your Mac and immediately press and hold Option + Command + P + R.reset PRAM/NVRAM
    3. Hold these keys for about 20 seconds. On Macs with a startup sound, release after the second startup sound; on Macs with an Apple T2 Security Chip, release after the Apple logo appears and disappears for the second time.

Method 2: Use Disk Utility for Repairs

Disk Utility can help fix disk permissions and other disk-related issues.

  1. Restart your Mac and immediately hold down Command + R to boot into Recovery Mode.
  2. From the macOS Utilities menu, select ‘Disk Utility’.
  3. Select your startup disk and click ‘First Aid’. Follow the on-screen instructions to complete the repair process.

Method 3: Reinstall macOS

Reinstalling macOS can be a solution for serious performance issues. Ensure you back up your data first.

  1. Backup your Mac using Time Machine or another method.
  2. Restart your Mac and immediately press Command + R to enter Recovery Mode.
  3. In the macOS Utilities menu, select ‘Reinstall macOS’ and click ‘Continue’. Choose your startup disk and click ‘Install’. Your Mac will download and install a fresh copy of macOS.

These advanced techniques are more complex and should be undertaken with caution. They can be highly effective for users looking to optimize their Mac’s performance beyond basic troubleshooting.

Maintaining Your MacBook for Optimal Performance

Regular maintenance is key to ensuring your MacBook, whether it’s a newer model or an older one, continues to run smoothly and efficiently. Here are some easy-to-follow tips that can help prevent future slowdowns and maintain optimal performance for your MacBook.

  • Regular Software Updates: Always keep your macOS and all applications up to date. Updates often include performance improvements and bug fixes. Check for updates by going to Apple Menu > System Preferences > Software Update.
  • Monitor Your Storage: Keep an eye on your storage space. A full hard drive can slow down your MacBook. Aim to keep at least 10% of your total disk space free.
  • Optimize Startup Items: Too many applications launching at startup can delay your MacBook’s boot time. Go to System Preferences > Users & Groups > Login Items to manage these.
  • Regularly Clean Your Mac: Physically cleaning your Mac can prevent dust buildup, which can affect its thermal performance. Use a soft, lint-free cloth for cleaning.
  • Run Disk Utility: Use Disk Utility‘s First Aid feature regularly to check for and fix any disk errors. This can be accessed via Applications > Utilities > Disk Utility.
  • Keep Desktop Clutter-Free: A cluttered desktop can slow down your Mac. Try to minimize the number of files and shortcuts on the desktop.
  • Check for Malware: Regularly scan your Mac for malware. Even though Macs are less prone to viruses, they are not immune.
  • Manage Browser Extensions: Too many browser extensions can slow down your internet experience. Keep your extensions to a minimum and uninstall those you don’t use.

By incorporating these practices into your routine, you can significantly enhance and maintain the performance of your MacBook. Regular attention to these areas will help ensure your MacBook remains fast and responsive.


In conclusion, maintaining the speed and efficiency of your MacBook is an ongoing process that combines understanding its performance, implementing fixes, and adopting regular maintenance practices. By following the steps outlined in this guide, from basic troubleshooting to advanced techniques, you can significantly improve and sustain your MacBook’s performance.
