Or erase the volume using a new feature of Monterey, as suggested by Apple.

If the in-built data encryption is insufficient, shred the Mac. You have already decided on the answer you want, and seem uninterested in technical details. I assume this also works for current MacOS I remember I read somewhere that specialists can recover data when it's overwritten a few times, but it apparently gets very difficult after about 8 passes (all from top of my head).The action will terminate automatically when your drive is filled with random data (with the message 'No space left on device') execute this command: cp /dev/random /Volumes/'yourdrive'.I would like to hear if this is working as expected I understand the drive is soldered to the main board so this would destroy the whole machine. Physically evaporating/grinding the drive is one step too far for me. Yes it's already encrypted but that's not good enough.Īpple's 'sudo diskutil secureErase' on SSD's errors with 'makes no sense'.
