Protected Screen is a system security application. It allows you to password your computer by launching an application.
When I tested the app, while the Mac was locked, the space where my dock used to be was flickering. This is not really a problem, since when the computer is locked, I am probably not going to be around to notice this. I was able to lock and unlock my Mac by entering the password.
In short, this is a nice app if you want to momentarily lock your Mac. You can also do this with a password-protected screensaver. But I like that you can lock your Mac by launching an app file, which comes in handy when you use scripts.
Pros
- It works well
- A few options
- Good for scripting
Cons
- You won't be able to bypass the screen without entering the password or shutting your computer down
