Password Protection bypassed by Mac Preview

We've created a password protected PDF and it works well, however, we recently learned that Mac Preview is able to open the PDF and ignore the password protection.

I don't have a MAC and I've searched high and low for this on Google to no avail... Need expert help.

Thanks!

This was a problem back in 2002 (http://www.planetpdf.com/mainpage.asp?webpageid=1976), but has since been fixed. Now you can even apply security settings in Preview. When you open a protected PDF document in Preview, you get a password dialog.

I read that article too, but the problem here is that we are in 2008 and this is a brand new MAC.  The pdf is created on a windows machine using Adobe Acrobat Professional, then distributed accordingly.  

Preview simply ignores the security implementations.

As it turns out... Adobe warns all users that not all 3rd party software comply with best practices...

"All Adobe products enforce the restrictions set by the Permissions Password.  However, not all third-party products fully support and respect these settings.  Recipients using such third-party products might be able to bypass some of the restrictions you have set."

That's a really ugly stain on Mac's inability to upkeep best practices.

My guess is "whatever Mac ships with today", since its a brand new laptop he is using.  Perhaps Leopard, but I'm not 100% sure... this is my Client's, client.

Which version of Acrobat was used to create the protected file? I assume you verified on a Windows machine that the protection in the file is actually working.
