No, this isn't a new version. v4.5.1 has been out for over 12 months.

Version: 4.3.9

It fails under Monterey. Launches, but without the familiar windows with the two locks, and it doesn't quit.

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.

2.0

Version: 4.1.0

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.

4.0.2

Version: 4.0.2

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!

Looks like there is no upgrade path for v3.x users :-(

The requirements needs to amended. It appears that as of V3.14, PDFKey Pro is Intel Only.

3.15

Version: 3.15

Requires Java Runtime 6. But I just installed the last Java Runtime 7 from Oracle. Must my Java downgrade to run. Bummer.

3.14

Version: 3.14

Uses Java Runtime, so doesn't work after installing Mountain Lion 10.8 unless you reinstall Java, so I gave it 1/2 star on stability. Due to security issues, I am reluctant to install Java on my Mac. It would be nice if the developer could recompile to run under Mac OS X.

0.5

Version: 3.13

Stay away... this is one of those developers who wrote a program for a very specific function and charges way too much, then the very specific function becomes freely available elsewhere and they continue to milk cash by not changing or adding much over the years and again charging way too much for tiny incremental upgrades. They prey on the unsuspecting.

I really like PDF Key Pro and used it for several years. For example, I receive regular invoices via mail which are encrypted. I know the password to encrypt the PDF but I prefer to save the PDFs as unencrypted documents for easy review and QuickLook compatibility. I also have a bunch of PDFs which I could not print or extract single pages. After squeezing them through PDF Key Pro, I can do all those things. Works great and received several updates. If you need this kind of software, PDF Key is a good joice.

Version: 3.11.0

Well, using Skim instead of Acrobat, you can still copy material from a "copy protected" document (though print protection is ok)... :-( Where is the protection if there is at least one (free!) app in the world that can break it with no effort?

Ok, I guess I do not understand this program. When I lock or encrypt a file I do this to the whole file, not copying and printing only. I have a PDF, that I saved over a year ago and cannot remember the "viewing" password, so this program does me no go. I guess there are some people who set PDFs so they cannot be printed or copied, but I have yet to encounter one.
