Question

PDF protection fails to allow selected rights

On MacOS Acrobat Pro 2024.005.20400, I can no longer delete and insert pages on duly password-protected PDFs (we want to protect the pages' content but leaving everything else possible). It says "operation not allowed" and then crashes. Last time I managed this operation was last december. Some newer version of Acrobat Pro since then must have introduced this bug.

You can easily reproduce this bug like I just did with any PDF file (protect, save, close, open, try to add a page or delete one -> pop up + crash).

Please help, since some of my company's critical documentation processes depend on it.

@Eric2391330 if the PDF is password protected,  then you need to enter the password to allow you to do the changes. there is a reason it's secured. Entering the password that is incorrect means you can't do the required changes as wanted. If you have a recent Time Machine backup or system restore point from before the issue started, you could try restoring your macOS to that earlier state. This might revert Acrobat Pro to a version where the bug wasn't present.

Thanks for your reply. But we are using password protection parameters that specifically allow inserting and deleting pages. After further investigations, some PDFs produce the error message and the crash, but most of our PDFs do not. All those PDFs are generated by InDesign, and then protected in Acrobat. They come from multiple MacBooks. We will let you know if we ever find anything the bad-behavioured PDFs have in common. For now we will be considering good or bad luck as our only explanation to this malfunction...
