FINALLY a simple solution!

Lock Pro is just what I was looking for: a way to easily lock apps for just a bit more protection from, say, the curious/prying eyes of flies on walls (read: kids) who IMO shouldn't be privy to things like household finances, private diaries, some SMS text conversations [because that's all we parents have left, ever since a gang of n'er-do-well teachers went and taught the kid to spell/read darnit] and so on. Works like a charm. I do wish it had a few more advanced options (e.g., different passwords for different categories of programs), and I also wish I had a better understanding of how it works so I could then understand how easy it would be for the single password to be cracked by a saavy flatmate -- but beggars are always looking for horses to ride, as the saying sorta goes. :) All in all a solid app -- thanks for filling a gaping void, devs!

Great, but some features not working

Overall, great app that does the job of locking MacOS apps and logging failed access attempts. However, I have been unable to take full advantage of the snapshot feature, which is supposed to use the webcam to take a photo when an incorrect password is entered even though I have enabled webcam access for the app. When an incorrect password is entered, the green indicator light turns on, and the log reads "password entry failed. Photo evidence was taken," but I cannot access the photos that were supposedly taken. The "show photos" button does not respond when clicked, nor does the "view" button under the checked "Capture Photo after Password failure" box. There is also no location or folder where said photos would be stored, at least that I can find.

I bought this app thinking it would lock the apps i dont want anyone to use. It works just as that and is great. One issue I have is the fact that no touch ID is added. It would make everything more simple.
