If Go to Page shows the wrong page of a PDF in Preview on Mac
In some PDFs, the pages are labelled with numbers that don’t match the actual positions of the pages in the document. For example, in some documents, the first five pages are labelled with Roman numerals i-v, and the remaining pages are labeled with Arabic numerals starting with 1, so the page labeled “1” is actually the sixth page in the document. In this case, the logical page number is “1” and the page’s position is sixth.
If the Go to Page command in Preview doesn’t display the page you expected, it might be because the document is set up to use logical page numbers.
In the Preview app on your Mac, choose Preview > Settings, then click PDF.
Select “Use logical page numbers”.
