Apr 22, 2016 12:14 AM in response to Ariel Yby Eau Rouge,Apple removed the option to Secure Empty Trash and Erase Free Space in Disk Utility.
Mainly because SSDs don't take kindly to being overwritten many many times.
They still support it in in Mavericks, Yosemite etc, interesting.

Well, they aren't likely to rewrite them.

Apr 22, 2016 12:36 AM in response to dialabrainby Eau Rouge,I don't expect them to rewrite them, but they could update their Mavericks/ Yosemite support pages to include information
on why using secure empty trash and erase free space may not be a good idea.

Apr 22, 2016 12:49 AM in response to Eau Rougeby dialabrain,They could. You could always send them feedback.
Speaking of not a good idea, has Apple ever said that's why secure empty trash was removed or is that just conjecture?

Apr 22, 2016 12:56 AM in response to Eau Rougeby chroot,Secure deletion methods are unreliable on flash storage and solid disk drives. The storage itself and how the operating system handles garbage collection means the storage is much more fluid. It's possible secure removal will overwrite the incorrect areas. It's both unreliable and reduces the life span of your SSD.
$ srm -rfv ~/.Trash
However, unless you have an old HDD with magnetic spinning disks called platters as opposed to an SDD then this isn't needed. If you are really that concerned about secure removal then enable FileVault--then your trash and removed trash is encrypted.

Apr 22, 2016 1:04 AM in response to dialabrainby Eau Rouge,As they decided to no longer include it in El Capitan, they could have added footnotes in the Mavericks/ Yosemite support pages.
The Yosemite page was last updated on the 23 Sept 2015, 7 days before El Capitan was launched, Apple decided
Secure Empty Trash was detrimental to the longevity of SSDs and would not be an option in future OS's, so a simple update to their Support
pages to include these findings would be helpful, after all our Hardware did not change overnight with the introduction to El Capitan.
Anyway I've got to go home for tea now. bye.

Apr 22, 2016 1:30 AM in response to Eau Rougeby dialabrain,FWIW… from About the security content of OS X El Capitan v10.11 - Apple Support
Finder
Available for: Mac OS X v10.6.8 and later
Impact: The "Secure Empty Trash" feature may not securely delete files placed in the Trash
Description: An issue existed in guaranteeing secure deletion of Trash files on some systems, such as those with flash storage. This issue was addressed by removing the "Secure Empty Trash" option.
Apparently their decision had nothing to do with "being detrimental to the longevity of SSDs".
