    Since upgrading to El Capitan, the possibility to secure empty trash has disappeared. Does anyone else have this problem?

    Tech details:
    System: 10.11
    iMac (27-inch late 2013)

    Yes, the option is gone. If you have an SSD then this is not really a problem, but on an HDD you will want to consider turning on encryption if this concerns you.

    I have the same issue. Why has the option for emptying the trash securely been removed?

    I agree. I can't believe it was removed deliberately... Thanks to KALLT for the reply.

    Thanks. Have you any idea why they did it?

    Someone quoted a study the other day, I can’t find it right now. The gist of it was that the function performed very poorly and was just not what you would consider a ‘secure’ erase, i.e. it was possible to restore a lot of data still. This raised a security concern and Apple’s formal solution was removing it altogether. Apple also says that it is counterproductive on SSDs due to their technical nature, as (1) the OS doesn’t control what the SSD’s micro-controller does when it is instructed to ‘overwrite’ the data and (2) that an SSD never actually overwrites but deletes data once a page is marked as stale. All in all, if you need this function for security reasons, you’re better advised to use disk encryption and a firmware password.

    Many thanks for this comprehensive answer. I really appreciate that you took the time to answer. The decision seems a lot less arbitrary now :)
