Diagnosis: The first step is to identify the cause of the issue. You can either visit an authorized service center or contact Apple Support for remote troubleshooting. The technician will ask you questions about the problem and may run diagnostic tests to pinpoint the issue.

Repair or Replacement: Once the problem is identified, the technician will determine the best course of action. Depending on the nature of the issue, they may repair or replace the faulty components. This could involve fixing hardware components like the display, keyboard, battery, or logic board, or addressing software-related issues such as operating system errors or malware infections.

Data Preservation: If your MacBook needs repair or replacement, it’s crucial to ensure the safety of your data. Most service providers will take precautions to preserve your files during the process. However, it’s always a good practice to back up your data before handing over your MacBook for service.
