On two Macs running 10.6, Preview will not open a password protected PDF that was sent to me. The same PDF opens on two other Macs running 10.7. Why is this?

    Or the PDF format version or encryption protocol is higher than the one supported by Preview in SL. What are they?

    use adobe reader, it's free

    I don't like adobe reader.  When  encrypted .pdf is opened I am unable to to put it in the finder file I want.  Adobe can't follow the finder tree so I have to save to the desk top and then open the doc in preview to file.  Time consuming and a pain.

     

    Please mac people, find away to prevent adobe from forcing us to use reader instead of preview.

    Adobe is doing nothing of the kind. Not intentionally, anyway. They add new features to each release of Acrobat (after all, PDF is their invention). It's then Apple's job to try and figure out how to handle the new features so Preview can open PDF files created with them. Apple is always playing catch-up with Preview with no help from Adobe to figure out how the format was changed/updated.

     

    It's no different with Office. MS has no need or reason to tell the people who update the free open source Office-like software (Neo Office, Open Office, etc.) what they're going to add to Excel, Word, or PowerPoint. It's up to them to figure out what MS did to change the format to add the new features, and then how to read and write them to be compatible. They too are always playing the game of catch-up.
