Downloading PNS 4 1.1.1 for Mac from our website was free. The program lies within System Tools, more precisely Automation. This Mac app was originally produced by Custom Solutions.
From the developer:
PNS 4 allows you to magnify and stare at four areas of the screen. When you launch PNS 4, you see the Control Panel on the left and four Display Windows to the right. The Control Panel has a Magnification slider for each Display Window. You can click the Hide button to hide the Display Windows; when the Display Windows are hidden, the button's caption changes to Show.
