Mechanical hard drives are still very good at providing a very large amount of storage at a low cost per-gigabyte. Since Apple started introducing computers with Solid State Drives, some people have been asking how to securely erase data on them like they used to be able to do on hard drives.
Well this is the fact, you can't securely erase them. The Department of Defense approved method for traditional hard drive secure erase is a 7x overpass of random data. Apple advises using Filevault to encrypt a boot drive, however that's not really secure because Filevault stores it's keys in memory and software tricks have been used to get the keys, thus the encrypted deleted data after being recovered off the SSD can be decrypted and read.
Also one has to give up the password for repairs to be done on the machine. In fact a nifty device from a company called Cellbrite that can read the storage off iPods, iPads and iPhones, even deleted data, even with password protection.
Does this also extend to portable Macs? Likely will be in the near future yes. Ideally it's best NOT to place any data into these newer machines that you rather not share with anyone else, it's the sad fact. However traditional hard drives are being phased out for the more shock resistant, non-bit rot suffering and faster SSD's instead of the traditional vulnerable spinning platters.
So because of this securely erasing SSD's would wear them out prematurely, and if under AppleCare or warranty would be a replacement cost to Apple that they rather not have to pay for, so Disk Utility will not secure erase these solid state drives.
Also if a laptop, TimeMachine local backup files also on the boot drive itself are being saved in hidden files. So even if you go and delete a file and manage to scrub the SSD by overwriting with random data, those hidden files still contain your unwanted data.
Therefore if you secure erase needs don't warrant total drive or machine destruction into a fine powder you may want to try my untested method below, however it's complex and time consuming, don't use often as it will prematurely wear out your SSD.
