Mach Wallpaper 3.0.5

This utility gives you access to several animated wallpapers and widgets for your desktop. The application sits on your Menu Bar from where you can change the way it operates, has simple-to-configure settings, and offers you support for multi-monitors.

You can easily change the current desktop image by going to Wallpaper Preferences and selecting the animated picture you need. The program also lets you put a digital or analog clock on your screen. This feature comes in handy if you need a larger clock to be displayed on your desktop (the clock's window can be resized to any resolution you like).

This utility can also display weather information based on your location. The details are accurate as I compared them with the info from a reliable weather forecast website.

My only concern is the fact that it uses an important amount of CPU resources (more than 10%) while playing the animated wallpapers on your desktop.

As for the rest, the app works great, offers you quality wallpapers and widgets, and comes with a reasonable price. In my opinion, you should first try the program on your Mac and then decide if it's worth buying its full version.
