Factory resetting your Macbook and other devices is an important task to complete prior to selling or giving them away. This is because all of your devices hold important personal data that can be accessed by someone with the proper knowhow. And while you can simply just wipe out your harddrive and delete all of your files, there are lesser known areas where Macbooks retain information.
While there are a few other things you will want to check before sending your Macbook off, performing a factory reset can take care of clearing out most of the data and information you wouldn’t want falling into the wrong hands. By the end of this article you should have a good understanding of what needs to be done to ensure the safety of your personal data.
Here are a few things that you will want to do prior to performing a system reset. These tasks will help secure your Apple ID account and any other accounts that may be tied to your Macbook.
- Go into iTunes and deauthorize your Mac.
- On the menu bar at the top of the screen go to Account, then Authorizations, and then select Deauthorize This Computer.
- You will want to sign out of any accounts currently signed in such as iMessage, Facetime, and iCloud.
- Navigate to your Macbook’s System Preferences and then go to Internal Accounts. From there you will see a list of different accounts that have access to your computer. You will want to sign out from these just to make sure that the accounts remain secure and accessible only by you.
- Reset your NVRAM. The NVRAM is where your computer stores data regardless of whether the computer is on or off. In order to reset your NVRAM, simply restart your Macbook and during startup hold the keys :Option, Command, P, and R for 20 seconds.
