Computers, like mobile phones, update quickly. With the continuous improvement of people’s living standards, it has gradually “transformed” from the original luxury goods into consumables today.

But, you know what? Maintenance on a MacBook usually extends its life.

About seven years ago, I bought my first MacBook, which I still use for various office tasks. The first MacBook Pro Retina was released in mid-2012, and it took me a summer’s worth of stocking up (I was a teenager, unemployed) to finally buy one!

Getting my first MacBook is amazing, baby. Of course, if you don’t always maintain your computer, it’s easy to slow down and get old. So I’m always looking for ways to improve the performance of my MacBook, and I’ve learned some interesting tricks over time that I’d like to share to make your devices that fast years from now.

1. Clear the system cache

Over time, the MacBook stores information in the system cache, such as system logs or large file caches, for faster startup, but in the long run the cache becomes useless and just takes up space on the hard disk. To free up memory, access the folder containing the above files and delete them:

· To go to the ~/Library/Caches folder, use the combination keys Command + Shift + G and then copy and paste the path for quick access.

Command +Shift + G go to the folder to enter.

· Delete files you think are unnecessary.

Cached files, such as Adobe Settings, uninstalled applications.

2. Disable unnecessary startup processes

Most of the time, when apps are installed, they are automatically set to run when the MacBook is started, even if it’s not necessary to run in the background. They consume batteries, shorten battery life and degrade device performance.

To disable these processes, access the Users and Groups Settings in system preferences:

Select an application and delete it with the “-” key.

3. Purge the memory

Opening a large number of applications or Web pages in the same session without restarting the MacBook can also accumulate cached files into memory and degrade performance. To free up space and make more memory available to the system, you can use a simple command at the terminal. Once opened, type Sudo Purge to delete all unused files from memory. It asks the administrator who ran the command for the password and enters it when prompted.

4. Reset NVRAM and PRAM

When you start adding many Settings, such as default speaker volume, display resolution, or more important information (such as kernel error logs), you may encounter some problems with these Settings. This information is stored in NVRAM (permanent random Access Memory) and PRAM (Parametric Random Access Memory) and is important for resetting and restoring normal computer performance.

Here’s what you can do, according to Apple’s support page:

Press this key combination to reset NVRAM and PRAM.

· Close the Mac.

· Press and hold down the four keys: Option, Command, P, and R immediately after starting up.

· Release the button after about 20 seconds, during which the Mac may restart.

5. Reset the SMC

After a while, the MacBook began to slow down for no apparent reason, and apparently with no problem. In reality, however, what happens is that some process in system administration deteriorates the performance of the machine or causes it to run abnormally. This may mean that the System Management Controller (SMC) is not working properly and resetting it can fix these problems. The process is a little different, and we should deal with two different cases:

Do not remove the battery:

· Close the Mac.

· Immediately after starting up, hold down the four keys: Shift, Control and Option, while pressing the power button.

· Hold the above button for 10 seconds and release it. If your MacBook Pro has Touch ID, Touch ID is also a power button.

· Press the power button to restart the MacBook.

Battery removable:

· Close the Mac.

· Remove the battery.

· Hold down the power button for 5 seconds.

· Reinstall the battery.

· Press the power button to restart the MacBook.

Cleaning your MacBook will help prolong battery life and keep performance at its peak all the time.

Of course, there are a number of other optimizations that can be performed on the end result, but only one at a time.

Take good care of your computer and trust that it will return the favor.
