I am using Sierra (10.12.4) on a MacBook Pro (mid 2014). I have enabled File Vault.
I have some small yet sensitive spreadsheets(<100k) that I have encrypted using the resident Disc Utility App. After creating an encrypted "Blank Image," I "move" the files into the mounted folder and then close the .dmg file. Is this a robust security measure? Does the unencrypted plain text still reside on the SSD? Could a recovery program access them? Is this a valid method of secure deleting files I no longer need? Thanks in advance for your help. PS - I have enjoyed the recent scripting episodes in your weekly newsletter. I'd like to see more. ----- David Russell
