How to revert links in a PDF of a screenshot
I apologize if this is not the right forum for help, but I was wondering if anyone could help me solve this problem, or at the very least understand what has happened.
I had a student who was visiting unauthorized websites and looking up videos to circumvent our schools content blocker, so I took a screenshot of his web history and google activity on youtube. I went thought print screen, and then saved the file as a pdf instead of printing it. Now, I've noticed that it is not a true static screenshot. The links in the screenshot work and now the links to the sites he was visiting link to "sign in to google" instead. I had no idea that pdfs of a print screen would do this. The student has since deleted his browsing history and now this pdf is useless in terms of evidence. If I try to revert to an older version it says that one does not exist. Is there any way to recover the pdf as it was originally saved?
I am using Mac 10.14.1 if that makes any difference
