I am trying to be a loyal Mac user and rely on Preview for management of my secure PDF files.

(I have used Adobe Acrobat Professional -AAP- for several years; I am trying to avoid installing it on my clean SL installation.)

1.) How do I use Preview to open a PDF file created, encrypted, and password protected in AAP? (I get an error: The file “Secure.pdf” could not be opened. It may be damaged or use a file format that Preview doesn’t recognize."

2.) Can someone give me simple step by step instructions to add Automator functions to Preview to allow me to encrypt and password protect individual files on a file by file basis?

All of this is very simple in AAP. Seems unnecessarily difficult in SL...

    Not answered. NO replies so it seems what I need to do is not simple. It means Preview is "not ready for primetime" as a professional PDF manager. Reinstalled Acrobat Professional. Marking as answered to remove from active list.

    I have observed the same thing. I created a similar post about a week earlier than yours and nobody had an answer either.

    Well, Dr. Midnight,

    There IS an answer. The "Password Protect PDF" file is a function in Automator that comes up as a Service in Preview.

    For me the problem is that Automator is not very intuitive and I am too old and too lazy to learn a new programming language just to replace/repair functionality that I had with Acrobat Professional in Leopard that got broken in Snow Leopard.

    Ok, - in truth - not broken, but moved and changed and made less easy to use. Preview becomes the default PDF handler in Snow Leopard. I though - ok - if Preview will do what Acrobat Professional used to do for me, I'll be a good little loyal Apple user and move from Acrobat Professional to Preview (and stop paying for Acrobat upgrades).

    Then I figured out it is a PITA to learn Automator and I learned that no one on this forum seems to know (or be willing to share) simple steps to enable one Automator Service.

    So I reinstalled Acrobat since I already own two licenses and since it does what I want simply and intuitively.

    By the way, thanks for checking in. Nice to know I am not all alone out here ....

    To password protect a file (I am using OS10.5 and Preview 4.2)
    File>Print>PDF (bottom left hand corner)>save as PDF>security options
    And add your password.
    Automator only seems necessary if you want to do the same process to a whole pile of files.
