My MacBook Pro is going to a new owner and I want to be certain the data is adequately erased on the internal SSD (PCIe flash). There are two Stack Exchange questions/answers that appear to present conflicting facts about whether or not using Disk Utility to erase a partition will make it sufficiently difficult enough to prevent data recovery:
Suggests that a simple "Erase" in Disk Utility will do the job:
Suggests that an SSD that has been erased can be reasonably recovered:
So based on this conflicting information, how can I be reasonably sure that the data on the erased SSD is gone and none-recoverable? It it true that when you format a drive on a MacBook Pro (late 2016) that the
TRIM function will erase all remnants of the files or are they still on the drive, ready for someone with a recovery program to access them?
I am tempted to try the
diskutil secureErase but I don't want to accedentiallly erase the wrong disk/partition nor put unnecessary wear on the SSD.
