PNS 4 is compatible with Snow Leopard (10.6) and higher.
If you like Point N See I believe you will love PNS 4 which is Point N See on steroids. PNS 4 has four Display Windows. Each Display Window is updated ten times per second with a Magnification of 1.0 to 6.0 in 0.1 increments.
PNS 4 is $10 shareware. You can try PNS 4 in Demo Mode for ten launches, after which you must donate and register to continue using.
Version 2.0.0 provides improved detail for Retina Displays.
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. You can click the Shrink label to show just the top portion and you can click the Crosshairs checkbox to add crosshairs to the Display Windows.
There are two Modes: Normal and Fixed. In Normal Mode, the Display Windows show the desktop around your mouse. In Fixed Mode, the Display Window stares at a fixed place on the desktop. The letter in the Display Window's title bar is that Window's Hot Key. The Hot Keys are "a", "c", "d", and "f". To make the first Display Window (with the "a" Hot Key) stare at a point on the desktop, move the mouse to that place and press the Command-Option-a keys. To revert the first Display Window to the Normal Mode, press the Command-Control-a keys. This allows you to magnify and stare at four places on your desktop while you work on something else.
Above is an example of how you might use PNS 4 to monitor four places on the display. The Control Panel on the left has been set to the desired Magnification for each Display Window. The four red dots mean that all four Display Windows have been set to Fixed Mode. The four Display Windows were resized (dragging a side or corner), and dragged to the bottom of the desktop. In this case, the Display Windows are set to stare at the S&P, the most recent email, battery status, and the Nasdaq.
The menu bar has a Display Window menu item to let you set PNS 4 to display 1, 2, 3 or 4 Display Windows.
