    Lock after signing is not effective on Acrobat XI - Mac

    francisaugusto

      Hi,

       

      I insert a digital signature (digital ID) on my document, and choose to lock it after signing. However, I can remove the signature by opening the document on Preview on Mac, thus rendering the lock function of Acrobat ineffective.

       

      Am I doing anything wrong here?

       

      All the best,

       

      Francis
