A great program. Works as advertised. Opened a locked 10 page document in 30 seconds. Worth the purchase price. It took a few hours for the activation code to be sent to me. I wrote them an email asking about this and received a prompt apology (and the activation code).

I use PDFKey Pro (v4.3.9) under macOS 10.13.4 and I discover a strange bug. When I set one of both protection options for copying or printing to allowed , I see that still both options not protected in the new created PDF! The info panel from the preview app shows that printing and copying is still allowed. I think this was quite wrong, wasn't it? Hoping of a fast update fixing this issue… thanks.

The software has been tested on 10.10.2 so it should normally work. Please try redownloading the software and write us at support@pdfkey.com if you still have problems!

I just upgraded my OS to 10.10 (Yosemite) and prior app to unlock PDFs so I could edit them (underline, highlight) was not working. I purchased PDFKey Pro and it worked for a while but then stopped working. I reinstalled and tried again but finally gave up and re-purchased the prior app (PDF Recover by Universe GMBH) that I had used for 10.6. It now worked fine. Don't know why PDFKey Pro failed to function but for me it was not a heart-warming experience.

Just bought this yesterday. It’s an ok looking app. But it does what it says on the tin and it darned easy to use. What sets it apart is Michele’s support and his responsiveness. He’s worked with me patiently when I mailed him about a set of documents that would not decrypt and has gone over and above what any other developer would do to help me. For this kind of service, I would have gladly paid twice over what he charges! Totally recommended!
