Impact: Securely deleting files can take a long time, with FileVault in place the protection is erasing data within an already encrypted volume.
Users and admins of computers containing sensitive information should be screened appropriately or additional security controls should be in place to prevent unauthorized access to sensitive information. It is possible for anyone with physical access to the device to get access if FileVault is not used, or to recover deleted data if the FileVault volume is already mounted. To erase free space on the boot volume $ sudo diskutil secureErase freespace 0 / Rationale: Securely removing files mitigates the risk of an admin user on the system recovering sensitive files that the user has deleted. The modern solution for quickly and securely erasing your data is strong encryption, with which mere destruction of the key more or less instantly renders your data irretrievable in practical terms.
There is still an option to erase free space from the command line but Apple has warned that encryption is a better solution From manual entry for diskutil Note: This kind of secure erase is no longer considered safe because modern devices have wear-leveling, block-sparing, and possibly-persistent cache hardware. In previous versions of the Benchmark srm was mentioned as an alternative to the removal of 'Secure Empty Trash.' With the release of macOS 10.12 srm has been removed.
For systems that are not using encryption and continue to use platter-based hard drives there is residual risk that deleted files can still be recovered from the file system. With the wider use of FileVault and other encryption methods and the growing use of Solid State Drives the requirements have changed and the 'Secure Empty Trash' capability has been removed from the GUI. Information In previous versions of macOS Apple included a capability to securely empty the trash that included overwrites of the existing data.
