    I want to prepare my laptop for selling.

    How can I reformat the drive in a secure way, and also re-install Sierra on my laptop? (I don't have the install CD).

    My computer does have a CD drive (2010 MBP).

    What I've settled on is (after deauthorizing any respective accounts):
    • Enable FileVault if not already enabled, and allow it to encrypt all contents on the computer's drive(s) (I believe this step is more important than ever before)
    • Then, boot into the Recovery HD (or, create an install/recovery USB flash drive, boot into USB Recovery drive), open Disk Utility, (unlock the drive(s) if necessary), erase the partition(s) with any OS(s)/User Files
    • Then, close the Disk Utility, and select the option to reinstall OS X
