2. Reset your MacBook Air

Once in a while, your MacBook Air needs a reset. We’re not talking about a full system wipe. Instead we are refreshing particular hardware components that control your Macbook Air. These are always good options and they should help all your computer’s parts work in sync with each other and speed up performance.

Basic reset by restarting

If you are one of those Mac users that never shuts down your Mac, it’s time you restarted your MacBook Air. A simple restart can sometimes do wonders for your MacBook Air. You can restart by clicking on the Apple Icon and then by clicking on Restart from the drop down menu.

NVRAM reset

NVRAM (nonvolatile random-access memory) is a small memory compartment where your Mac stores and quickly accesses certain settings. NVRAM stores settings such as volume, resolution, startup selections, time, and recent recovery information. NVRAM storage varies by Mac and your compatible devices. To reset NVRAM,

  1. Shut down your Mac
  2. Turn it on and hold down Option + Command + P + R
  3. Hold the four keys for about 20 seconds
  4. You can release the keys after the second startup sound (or after startup is complete if you do not have startup sounds)

Then, when your Mac finishes starting up, you can navigate to System Preferences to re-adjust settings that have been reset.


3. Free up your disk space

Because of their compact size, MacBook Airs have modest-sized hard drives. Monitor your available storage regularly. Consider copying large files (movies, music, and photography) to an external hard drive for your Mac.
To check your free disk space, open Apple icon > About this Mac > Storage

If your MacBook Air is giving you fits, you may need to reinstall your operating system. To do so, turn off your MacBook Air. Once your computer is completely off you can turn it back on. Hold down Command + R on your keyboard immediately after pressing your Mac power button. Continue holding these buttons until you see the Apple logo. You’ll soon see the MacOS Utilities box.

  1. Choose Reinstall macOS from the utilities window
  2. Click Continue
  3. Select a startup disk + click Install 
  4. Your Mac restarts after installation is complete
