Every Mac includes a utility called System Preferences, to change hundreds of settings within OS X. System Preferences has many features, but there are many useful features hidden within OS X that are not included in System Preferences. Yosemite Preferences unlocks those features in a beautiful, easy-to-use widget.
Yosemite Preferences was designed to take advantage of the new transparency and vibrancy effects in OS X Yosemite, giving it a unique look and feel that blends in with the color of your wallpaper.
Yosemite Preferences 1.0 includes 20 powerful hidden preferences that enhance your Mac, with more to come in future updates. If you would like to see a feature added to Yosemite Preferences, feel free to submit your request for consideration.
