I've had two MacBooks since they first debuted in 2006, and I've learned that my devices last long because I care for them well. Cleaning my Mac regularly is essential to improve performance, free up storage space, and extend its lifespan. To do this, I use a dedicated app called Avast Cleanup, which identifies apps I don't use, finds duplicate files, auto-updates software, and provides antivirus protection. Additionally, I clear disk space by deleting unnecessary files, cache on my browser, and manage storage and apps on my Mac. If you're not comfortable using an app, you can also clean your Mac manually using Terminal commands to stop processes, clean RAM and disk cache, and find and delete large files. Finally, it's essential to keep the outside of your Mac clean by using soft microfiber cloths and avoiding harsh chemicals. By following these steps, you can keep your Mac running smoothly for years to come.
