You have used your Mac for a long time and it becomes slowly, or you want to sell your beloved MacBook to someone else to buy a new one. No buyer would feel interested in buying a computer full of your data. Therefore, it is a good idea to wipe out completely the data in order to refresh your Macintosh like new. In this article, we will show you steps to factory reset you MacBook.
Reset Mac to the Factory Settings
Note: Make sure your Mac is connected to the Internet so that you can download the latest copy of Mac OS X
- Clone the hard drive
First, you need to clear the MacBook before factory resetting it. To erase the hard drive on a MacBook or Mac, you should use a third party app to get the full functionality. You can use apps like Super Duper or Carbon Copy Cloner to clone the hard drive to another one for the data safety. Connect the external hard drive to PC, set the internal drive as source and external as destination if you use Carbon Copy Cloner app. You will have to turn off file vault to reset the Mac.
- Turn FileVault Off
FileVault is a silent protector on your MacBook. Its mission is to encrypt your files on the hard drive. However, you should turn the FileVault off before factory reset. Just go to System Preferences –> Security –> Privacy –> FileVault. Check that the new box displays ‘FileVault is turned off for the disc’. If not, click on the small detachable lock icon at the bottom left and then click ‘Turn off FileVault’.
- Unauthorize iTunes
By default, iTunes authorizes all your iDevices through your Apple ID. In case you sell your MacBook to a new buyer without authorizing the device on your iTunes, it can make the new user face troubles. Therefore, you should unlink the Mac you intend to sell from your Apple account using iTunes. Open iTunes and click on Store –> Unauthorize This Computer. Enter your Apple ID and password and click on Unauthorize
- Log out of the iCloud
Head to System Preferences, and open iCloud, click on ‘Sign Out’. You should also delete your personal data from the Mac’s local storage, click on ‘Delete from Mac’ on each popup you see.
