Open in Preview, Click on File>Print. Bottom left corner of dialogue box click PDF. Click on Save As PDF... and then on Security Options in new dialogue box. You will the get a dialogue box that will offer you security options.

If you want really good PDF security options, you pretty much are going to want to use Acrobat pro or PDF Pen Pro. I don't know if they can restrict more than what Preview does, but it is probably more native.

If you just want to prevent Preview from making edits to the file, you can always lock the file in the Finder to stop it being over-written.

Preview uses the same security that Acrobat does: it's the PDF standard for security. However, Acrobat will have greater ability to configure and control that security.

It's worth mentioning that there are programs on the internet to strip the security from PDFs, so technically: if someone does want to copy, print or modify the contents, you can't stop them.

After converting a document to a .pdf you will not easily be able ( accidentally ) change it. Changing the text of a PDF requires several button clicks and 'Pro' software to do it.

As others have said, if you are looking to ensure the document CANNOT ever be changed by someone, that is impossible. You can only make it MORE difficult to change it.

I'm new to Mac (finally switched from my Windows PC) and I find this useful. I had no clue that Preview can be used to protect pdf files. On my Windows laptop I was using: this desktop utility to password protect and lock my PDF files but unfortunately it does not work on my Mac. That Windows utility protect PDF with both user (no one can access PDF file without entering password) and permission password (restrict PDF printing, editing, copying, etc.) but it seems preview can only protect PDF file with open password. I guess I have to buy the monthly subscription of PDF Acrobat now!

the OP's OpenOffice should offer the same security options as Acrobat and Preview. When doing the original "Export as PDF..." it is a simply matter of setting a password(s) on the "Security" tab and then checking the desired options.

Preview is an obnoxiously useful app. It's not spectacular at anything, but it's pretty damn good at an awful lot of things.
