Similar problem with AmEx statements. I like to delete the extraneous pages from the PDF, the “backsides” of two-sided paper copies. But system will not let me delete pages from the document.
Error message: Document permissions do not allow this action. Enter the document owner password to permit it. Password ____
I found that if I generate a PDF from that file then it allows me to do it – making a copy, or “Duplicate” in the Finder, does not work. Only Print > “Save As” another PDF.
So the workflow is
-Download statement.pdf from AmEx.com … (Hazel moves to proper directory)
-Open statement (with PDFPen Pro; Preview also works)
-Print > PDF > Save as PDF statement_copy.pdf
-Delete extraneous pages
-Delete original statement.pdf
-Rename statement_copy.pdf to statement.pdf
One of the great high points of my life would be to automate or improve this tedious process, and I assume it would be doable with Keyboard Maestro or Automator or whatnot (that reminds me of Lydia’s quote from Better Call Saul!). The times I have started to try it though, I got distracted with life or with something else.
