A factory reset clears these issues, giving the system a fresh start. Additionally, if a Mac is being sold, donated, or transferred to another user, a factory reset ensures that all personal information is completely removed. It can also help resolve recurring software problems that are difficult to fix through normal troubleshooting methods.
