Supported PDF functionality – Mac OS 10.4
I’m always being asked — how does the implementation of PDF on my Mac compare to what Adobe offers in Acrobat and Adobe Reader. So, I went to PDF guru, Leonard Rosenthol , and he prepared a chart, which I then jazzed up using InDesign to create layers and added interactive buttons in Acrobat to allow you to select different views of the document to see what Apple can Read/Write, Read Only, or have Partially Implemented on the Mac platform (OS 10.4/Tiger). And I’ve outlined what is not supported at all

As background information – the PDF Specification – version 1.x through 1.7 – has been published by Adobe and made freely available on our website. Vendors choose to implement features/functionality as it makes sense for their use.
And of course… if there is an error in this chart, please let me know.

Hey Lori – this is a terrificly useful resource – thanks!
Excellent resource.
Though … my stupid Firefox automatically opens PDFs in Mac’s Preview (though the Finder opens them in Acro).
So right after it downloaded, it opened in Preview and I’m like … hmmm … these buttons aren’t working … LOL.
Hey Lori, any plans on updating this for Leopard?
Thanks Lori for the pfd_reference… Usefully
