Performing a factory reset on any of your tech devices is often recommended as a solution to many issues that may occur. In the case of a MacBook Air, this task can be performed to increase performance and restore your laptop to its former glory.
If you’ve opted to sell your MacBook Air to someone else, a factory reset will ensure that all of your private and personal information is deleted. Ensuring that another user can log in and begin using your former MacBook Air is also important to seller ratings and it relieves the hassle of having to remove your information after the transaction is completed.
By backing up your MacBook Air with Time Machine and performing a factory reset of your MacBook Air, your machine will feel like you just unboxed it for the first time.
