Keeping in communication with the service team can help you stay informed about the progress of your repair.
Will I lose data if my MacBook screen is damaged?
In most cases, a damaged MacBook screen will not result in data loss. The data is stored on the hard drive or SSD, which is unaffected by damage to the display. However, if the damage is severe and impacts internal components beyond the screen, such as the logic board, there is a potential risk for data loss.
If you’re concerned about data integrity, consider backing up your files before bringing your MacBook in for repairs. Utilizing Time Machine or other backup solutions can help ensure your data remains safe during the repair process. It’s always better to be cautious, as unexpected failures can occur during repairs.
