MacBook Maintenance Guide: Daily Care, Disk Cleanup, Temperature Control, and Battery Replacement

Preface

Whether for study or work, a computer is an essential tool for IT professionals, and its longevity depends not only on its specifications but also on proper maintenance.

My Computer

The author describes the first and second computers, highlighting the second MacBook Pro 13" purchased with personal earnings and used for six years.

MacBook Pro 13" features a sleek aluminum body, high‑performance processors (M1 or Intel), strong GPU, Retina display with True Tone, full‑size backlit keyboard, multiple USB‑C/Thunderbolt 3 ports, long battery life, and efficient cooling, making it suitable for professionals.

The purchase was motivated by the belief that programmers need a Mac, despite the cost.

Daily Maintenance Measures

Update the operating system and applications regularly.

Clean disk space using built‑in tools or third‑party software.

Disable unnecessary startup items.

Clean the keyboard and screen with a soft microfiber cloth, avoiding chemical cleaners.

Control temperature by ensuring good ventilation.

Use the original charger and manage battery cycles, avoiding over‑charging.

Back up important data to external drives or cloud storage.

Install reliable antivirus software and perform regular scans.

These steps help keep the MacBook in good condition and extend its lifespan.

Maintenance Tips

Keyboard & Screen Cleaning

Keyboard cleaning:

Turn off the MacBook and disconnect power.

Use a canned air blower to remove dust, keeping the airflow vertical.

For stubborn stains, use a small vacuum or soft brush.

Avoid liquids or spray cleaners on the keyboard.

Screen cleaning:

Wipe the screen with a soft, lint‑free cloth; use a dedicated screen‑cleaning cloth if possible.

Avoid organic solvents, alcohol, or ammonia‑based cleaners.

For tough stains, lightly dampen the cloth with water.

Additional advice: keep hands clean, use a protective cover when closed, and regularly check for debris.

Disk Space Cleanup

Remove junk files using the built‑in “Optimize Storage” feature or tools like CleanMyMac.

Regularly clean the Downloads folder.

Identify and delete or move large files (movies, music, old apps) using Finder or tools such as GrandPerspective or DaisyDisk.

Delete unnecessary email voicemails.

Manage iCloud storage and remove unneeded files.

Uninstall unused applications.

Clear browser caches.

Delete unnecessary email attachments.

Temperature Control

Clean the ventilation ports and fans regularly.

Avoid prolonged high‑load tasks; take breaks to allow cooling.

Use a cooling stand to improve airflow.

Limit background processes and close unnecessary apps and tabs.

Adjust power management settings to lower CPU performance if needed.

If the MacBook overheats consistently, seek professional repair.

Battery Replacement

The battery eventually failed, prompting a costly official replacement quote (~2000 CNY). The author purchased a third‑party battery for ~300 CNY and replaced it following the manual, extending the laptop’s life by another three years.
