  • Make sure there is no personal digital content in the form of Apps/Song/Movies or documents.
  • For Mac, make sure that there is no Firmware Password that is set.

  • Delete all personal data. Make sure you have a backup of the same.
  • Remove any applications you may have installed.
  • Sign out of all accounts: Gmail, Hotmail, Facebook, iCloud, Apple ID…
  • Delete any user accounts you may have created. Leave a single admin account.
  • If you have used any Encryption service then make sure you turn off encryption before selling the device. This is more of a precaution to prevent issues that may arise in the future.

  • De-register from iMessage.
  • Remove any custom settings, passwords (Firmware Password) that may compromise your security or prevent the user from fully using the device.
  • As a good measure completely erase the hard drive of your device.
  • Document items such as OS Version, Serial Number for your own reference.

Enterprises may take additional steps

  • To ensure data security, Enterprises may perform Secure Erase or drive replacement to prevent recovery of corporate information, when assigning devices to employees or selling them out in the market.
  • Enterprises should also protect against Activation lock. When collecting iOS Devices, assigned to an employee who is leaving the organisation, always check to make sure that the device is not locked to the employees Apple ID.

These are some of the things that you can do to make the transaction easy on both the sides.
