I recently sold a MBP with a T2 security chip hoping that my data is completely erased, beyond recovery. My understanding is that the “Erase all content and settings” feature securely erases the encryption key stored somewhere (I forgot the name).
If I didn’t use this “Erase all content and settings” feature, and just went into disk utility and erased/reformatted the partition from there, can I be sure that the encryption key was securely erased? Because as “careless” as I am I just did that and didn’t read Apple’s specific T2 chip instructions.
