[MacTUG] Secure Erase of SSDs

[Dani Roloson]

Colleague has a question about preparing Macs for surplus and is wondering what others do on campus.

------------------------------------------------------

What is the best way to securely erase the SSD in an Apple computer that is going to surplus?

The Apple web site:  https://support.apple.com/en-ca/HT208496
How to erase a disk for Mac - Apple Support<https://support.apple.com/en-ca/HT208496>

Use Disk Utility to erase (format) a hard disk, flash drive, or other storage device for Mac.



says to use Disk Utility – it does not specify that a particular version has to be used.  Article is from September 2018.

In general, data on SSDs can be rendered unreadable by encrypting the drive and then removing the encryption key, but how to do this in MacOS?
