Apple retained srm in El Capitan, probably to placate users who chose to retain their illusions regarding secure data deletion for a little while longer. To ensure your data remains secure throughout that period of time, use FileVault: macOS Sierra: Encrypt the contents of your Mac with FileVault.ĭon't be misled into believing some third party product is capable of securely erasing unencrypted data either. Data doesn't suddenly become sensitive just before a user decides to erase it it's sensitive the moment it is created and ought to be treated that way for as long as it exists. The only way to ensure data security from its creation through its destruction and all states between those two is to encrypt it. There are other reasons in addition to those, none of which are unique to the Mac. The introduction of solid state (flash) memory rendered the feature completely pointless.

There are many reasons Apple removed that feature, not the least of which it was never capable of ensuring secure data destruction with complete effectiveness, even with magnetic media. 'Secure Empty Trash' is gone, for good reason.
