Hi Paul, If you wish to securely wipe your drive then you are best to start the machine up from a USB or DVD installation disk then run disk utilities from that USB or dvd media then secure wipe the machines internal drive And once that is done install the OS to a basic installation and I would stop at the point where you get asked for the country
This being the point the new user would start the machines setup from. The reason behind the secure boot from external media is because you can't secure wipe a drive you are running from. Good luck. -----Original Message----- From: macvisionaries@googlegroups.com [mailto:macvisionaries@googlegroups.com] On Behalf Of Paul Hopewell Sent: Thursday, 1 March 2018 12:03 AM To: macvisionaries <macvisionaries@googlegroups.com> Subject: Preparing a Mac for disposal Hi Andrew and Nickus, Many thanks for your help. I hope to sell or give away the old Mac but if no one wants it I will have it recycled. I am a bit paranoid about security and so want to be sure that all my private data is really gone before moving the Mac on. So can I use the disk utility part of the recovery manager to securely erase my hard disk and then use the Install Mac OS part of the recovery manager to re-install El Capitan? Or if I just use the Install Mac OS part of the recovery manager does that also reformat my hard disk so that I do not need to use the disk utility?
