Q: what happened to securely empty trash in Finder?

It while it can be performed from the terminal I advise against it as it can potentially destroy every bit of data on your HD and render your OS a blank slate.
If you need security look into encrypting with file vault 2

Do you know what is the issue with SSDs? Why doesn't srm do what one would expect it to do with those? And since it is not doing what one would expect it to do, do you know what it is doing?

Dec 17, 2015 7:13 AMby JimmyCMPIT,the methodology with SSD design and functionality makes apples implementation of secure delete ineffective. since Apple is focusing on a line of computers with solid state drives Apple may have felt it was no longer a valid feature for OS 10.11
Apple may feel they have addressed any potential security issues with FileVault making a replacement for secure delete unnecessary.
